A Color Doppler test is a non-invasive test used to estimate the speed of blood in blood vessels by turning high-frequency sound waves into images. It is done as an alternative to more invasive procedures such as angiography, in which dye is injected into blood vessels for them to show up on X-Ray screens clearly.

Color Doppler test is used to diagnose conditions like:

• DVT (Deep Vein Thrombosis),

• Blocked arteries,

• Blood Clots,

• Congenital heart disease,

• Valves functioning poorly,

• Bulging and Narrowing arteries,

• Decreased Blood flow in any part of the body.

If you or someone close is advised for a Color Doppler test, Heritage Hospitals should be your first choice. With our trained staff and state-of-the-art infrastructure, we strive to provide the best results.

A Treadmill test aims to determine the effects exercises have on the heart. Exercise helps doctors to diagnose coronary heart disease and arrhythmias. The test involves a patient walking on a treadmill whose speed and inclination gradually increase. The results thus obtained show how a patient’s heart responds to the stress of different levels of exercise.

This procedure monitors your blood pressure, heart rate, and ECG before, during, and after the test. The patient must wear a front open gown to attach adhesive electrodes to the chest. The place of the electrode connection is cleaned with alcohol. You are then asked to walk on a treadmill with increased speed and inclination at set times. You are monitored, and if there is a problem, the technologists immediately abort the test. Your heart rate, ECG, and Blood pressure are then recorded at the end of the test, and the report is provided.

The Patient is advised to wear comfortable shoes to walk on the treadmill and not to eat or drink anything for at least 2 hours before the test. 

Heritage Hospitals should be your first choice if you or someone close is advised for a Treadmill Test. With our latest diagnostic aids, we strive to provide the best results at a nominal price.

ECG test is a standard and painless procedure to detect heart-related issues. In this procedure, the leads from the ECG machine are connected to the limbs and chest of the patient. Sensors attached to his skin detect the patient’s heart’s signals each time it beats. These signals are recorded and printed by the machine.

Two types of ECG include the Holter Monitor test and Implantable loop recorder. Specific symptoms that indicate the need for an ECG include chest pain, dizziness, palpitations, Rapid pulse, shortness of breath, etc.

 ECG Computerised can be used to detect various heart problems like

• Arrhythmias

• Heart Attack History

• Blocked or narrowed arteries

• How well do specific heart treatments work

Heritage Hospitals should be your first choice if you or someone close is advised for an ECG test. With our trained staff, comprehensive care and the latest diagnostic aids, we strive to provide the best results.

A small monitor about the size of a mobile phone and battery-operated is called a Holter Monitor. It is a wearable and portable device that is a type of ECG and records your heart’s rhythm. You need to wear a Holter monitor for 24 to 48 hours for it to record your heart’s electrical activity. Wearing a Holter monitor is not painful, and one can go about daily activity while having the monitor attached to one’s body. However, a few things which should be avoided while wearing a Holter Monitor are bathing, swimming, showering, having an X-Ray, etc.

Holter Monitor test is recommended if your doctor observes unusual heart rhythm so that he can find reasons of-

• unexplained fainting and dizziness

•  Heart palpitations

• see if your pacemaker is working right

However, Holter Monitor is not recommended if one needs urgent care and that is getting delayed. 

If you or someone close is advised for a Holter Monitor Test, Heritage Hospitals should be your first choice. With our trained staff and the latest diagnostic aids, we strive to provide the best results at a nominal price.

Coronary Angiography Procedure is recommended when your doctor feels you are at risk of a heart attack. It involves taking an X-Ray by injecting contrast dye into your arteries and watching on screen how the blood flows. The resulting images obtained are termed Coronary angiograms.

During Coronary Angiography, a fine tubing is passed through a site over the wrist or groin through the main artery (Aorta) to reach the coronary ostium, from where radiocontrast material (dye) is injected to visualise the coronary arteries and look for blockage. The procedure is usually done under local anaesthesia so the site area is numbed and the patient doesn’t feel pain.

Coronary Angiography is an OPD procedure, and the patient can return home on the same day in a few hours.

Heritage Hospitals should be your first choice if you or someone close is advised for a Coronary Angiography. With our trained staff and the latest diagnostic aids, we strive to provide the best results.

Pulmonary Function Tests are often done to check the functionality of the lungs. These tests are non-invasive and measure lung capacity, lung volume, rates of flow, and exchange of gases. Pulmonary Function Tests can be done with two different methods. They are  Spirometry and Plethysmography. These two methods may also be combined to gather information as per the need of your Pulmonologists. 

In the Spirometry Pulmonary Function test, we use a device with a mouthpiece hooked to an electronic device. 

In the Plethysmography Pulmonary Function test, the person stands on a square-looking air-tight box to complete the tests.

The data collected through PFTs include 

• Tidal Volume

• Minute Volume

• Residual Volume

• Tidal capacity

• Total lung capacity

There are various reasons why your Pulmonologists advise you for a Pulmonary Function Test. Some of these reasons are Allergies, Respiratory infections, Asbestosis, etc. Your healthcare provider may also suggest a PFT test for your routine check-up. 

Heritage Hospitals should be your best choice if you or someone close has been advised for a PFT test. Our excellent results and advanced care help doctors to design better treatment plans.

Bronchoscopy test allows the doctor to look at your lungs and air passage to identify lung diseases and infections caused by bacteria, viruses, etc. In the Bronchoscopy test, a flexible bronchoscope is passed through your nose/mouth, throat and lungs d to perform the test. However, in specific scenarios, a rigid bronchoscope is used if a large object is stuck in your air passage or has profuse bleeding in your lungs. 

Some common reasons your Pulmonologists suggest a Bronchoscopy test include:

• Infection, 

• Persistent cough

• Something unusual was seen during a chest X-Ray. 

There are no specific risks in Bronchoscopy tests; however, some complications include Fever, Collapsed lungs, or bleeding. 

Bronchoscopy test is a minimally invasive procedure that needs Anaesthesia to be performed. You are monitored after the process and aren’t allowed to eat until the numbness in your throat disappears. After the Bronchoscopy test, your doctor might put you on a strict diet. It may also happen that tissues for biopsy are taken during the Bronchoscopy test; those results might take longer because of specimen separation.

Heritage Hospitals should be your best choice if you or someone close has been advised for a Bronchoscopy test. With our advanced care and latest critical facilities, we aim to provide better results.
 

An allergy test is an outpatient skin pricking test to identify various allergens' sensitivity. It shows how one’s lungs respond to specific allergens. An allergy test is a simple, safe, non-invasive and quick result-giving test that helps you manage your heart conditions and avoid triggers. 

In an Allergy test, your skin is pricked, and a small amount of allergen is put under the surface to see the body's response to that allergen. There is no specific age group on which this test is carried out. It can be performed for all age groups and is carried out on the inner forearm. 

The three most common types of Skin allergy care tests include:

• Skin prick testing

• Intradermal skin testing

• Patch testing.

During the test, certain things in your body include more acid production in the stomach, stimulation of nerve endings, widening of blood vessels, etc. Skin prick tests may cause mild discomfort to the patient. If he is allergic to the substance, he may have symptoms like mild fever, runny nose, rashes, etc. 

Heritage Hospitals should be your best choice if you or someone close has been advised to get Allergy tests done. With our specialists who have years of experience and our latest critical care facilities, we strive to provide the best outcomes.

Polysomnography is a sleep test conducted to diagnose sleep disorders. In Polysomnography, pulmonologists record:

• Brain waves

• The oxygen level in your blood

• Heart rate

• Breathing

• Eye and leg movements during sleep

Sleep studies are done at sleep centres or a sleep disorder unit within a hospital. The most appropriate time for this test is at night; however, it is also done during the day for those with night shifts at work. If you are already diagnosed with a sleeping disorder, polysomnography helps determine the patient's treatment plan. A sleep study can also be done at home using different devices. Home sleep apnea test records your breathing and airflow. Some styles also record information on blood vessels.

Polysomnography/PSP test is done to identify when and why your sleep gets disrupted. One typically goes through multiple sleep cycles, and sleep disorders disrupt these cycles and sleep. 

Our Pulmonologists recommend a PSP test when you are diagnosed with 

• Sleep apnea

• Narcolepsy

• Unusual behaviour during sleep

Polysomnography is a non-invasive, painless test; skin irritation is the only side effect caused due to the test sensors attached to your skin. 

Heritage Hospitals should be your best choice if you or someone close has been advised for a Polysomnography test. With our excellent results, advanced care and critical care facilities, we strive to provide better results.

A treatment called an upper GI endoscopy, often known as an EGD (esophagogastroduodenoscopy), is used to identify and treat issues with the upper GI (gastrointestinal) tract.

Your oesophagus, stomach, and the first segment of your small intestine comprise the upper GI tract (the duodenum).

An endoscope is a long, flexible tube used for this surgery. On one end of the tube, there is a little light and a camera. You pass the tube through your mouth and throat. After that, it moves gradually through your stomach and oesophagus before entering your duodenum. On a monitor, video images from the tube are displayed.

The endoscope may also accommodate small instruments. One can use these tools to:

• Eliminate anything lodged in the upper GI tract, such as food.

• injecting liquid or air

• Reduce haemorrhage

• Perform operations like laser therapy, endoscopic surgery, or open (dilate) a small region.

• Take tissue samples for Biopsy.

Heritage Hospitals should be your first choice if you or someone close is advised for a Gastro Endoscopy in Varanasi. With our trained staff and the latest diagnostic aids, we strive to provide the best results.
 

A colonoscopy is a procedure to see into the large intestine, which contains the colon, rectum, and anus. It is a form of endoscopy that uses a flexible tube with a lit camera introduced into your body as the instrument. Endoscopes come in a variety of varieties for use in various body sections. The colonoscope enters your colon through your rectum and anus during a colonoscopy. It transfers images of your big intestine's inside to a screen along the way.

A colonoscopy can be therapeutic, diagnostic, or preventive; it is frequently all three. If you have a statistically increased chance of developing colorectal cancer, your healthcare practitioner can suggest getting a colonoscopy for routine cancer screening. The greatest approach to prevent colorectal cancer is through screening because it can strike anyone at any time without prior notice or symptoms. Your gastroenterologist may remove worrisome tissues during screening for testing and prevention.

The followings are the illnesses or disorders that a colonoscopy may assist in diagnosing:

• Crohn's disease or ulcerative colitis are examples of chronic colitis.

• Ischemic colitis with intestinal ischemia.

• Diverticulitis and Divericulosis.

• Both perforations and ulcers.

• Blockages in the large bowel.

• Colon cancer and colorectal polyps.

In a kidney biopsy, a small portion of kidney tissue is removed so that it may be studied under a microscope for indications of injury or illness.

To identify a potential kidney issue, your doctor might advise a kidney biopsy, also known as a renal biopsy. It can also be used to assess the severity of a kidney problem or to track the effectiveness of kidney disease treatment. You might also require a kidney biopsy if you have had a failed kidney transplant.

Most frequently, a doctor will do a kidney biopsy by puncturing the skin with a tiny needle. This is called a percutaneous kidney biopsy. The doctor can more easily remove kidney tissue using an imaging gadget.

A kidney biopsy might be performed to:

• Help create treatment recommendations depending on the kidney's state and diagnose an issue that can't otherwise be found with the kidney.

• Determine the rate of progression of kidney disease.

• Identify the extent of renal disease or another disease's damage.

• Analyse the effectiveness of renal disease treatment.

• Check on the condition of a transplanted kidney or determine why one isn't functioning correctly.

Heritage Hospitals should be your first choice if you or someone close is advised for a Kidney Biopsy in Varanasi. With our trained staff and the latest diagnostic aids, we strive to provide the best results.

A thorough analysis of your heart's electrical activity is called an electrophysiology study (EP study). Electrocardiogram (EKG) tracings and electrical measurements inside your heart are produced using cardiac catheters and computers.

Your cardiologist may safely replicate your aberrant heart rhythm during the test, after which you'll receive various drugs to determine which one best regulates the rhythm.

Your doctor uses the EP study to:

• Learn the cause of your dysrhythmia or arrhythmia, which is an irregular heartbeat.

• Identify the location in your heart where the aberrant heart rhythm starts.

• Choose the best treatment for your irregular heart rhythm.

When other tests, such as a regular EKG, Holter monitor, event recorder, stress test, echo, or angiography, cannot offer enough data to fully analyse your aberrant cardiac rhythm, your doctor may advise an EP study.

The operation is conducted in a clinical setting with strict controls in an electrophysiology lab. Cardiologists and electrophysiology-trained nurses carry out the operation.

In general, an EP study is a highly safe technique. There are hazards, though, just like with any invasive operation. To reduce these dangers, certain safety measures are implemented. Any worries about the procedure's hazards and advantages should be brought up with your doctor.

Heritage Hospitals should be your first choice if you or someone close is advised for an EP Test in Varanasi. With our trained staff and the latest diagnostic aids, we strive to provide the best results.

An electroencephalogram (EEG) test uses tiny metal discs (electrodes) connected to the scalp to assess electrical activity in the brain. Electrical impulses are the primary means of communication among brain cells, which are always active—even while you're asleep. Wavy lines can be seen during this activity on an EEG recording.

One of the primary diagnostic procedures for epilepsy is an EEG. Other brain abnormalities can also be identified using an EEG.

When diagnosing brain illnesses, particularly epilepsy or another seizure disorder, an EEG can identify variations in brain activity. An EEG could be useful for identifying or treating:

• Brain cancer

• Head injury-related brain damage

• Various conditions can lead to brain dysfunction. (encephalopathy)

• Sleep problems

• Inflamed brain tissue (herpes encephalitis)

• Stroke

• Alzheimer's disease

A chronic coma patient's brain death may also be verified using an EEG. For a patient in a coma that has been medically induced, a continuous EEG is utilised to determine the appropriate level of anaesthesia.

Heritage Hospitals should be your first choice if you or someone close is advised for an EEG test in Varanasi. With our trained staff and the latest diagnostic aids, we strive to provide the best results.

An electromyography (EMG) diagnostic test is used to evaluate the condition of the muscles and the nerve cells that govern them. (motor neurons). The results of an EMG can identify difficulties with nerve-to-muscle signal transmission, muscle dysfunction, or both.

Electrical signals sent by motor neurons trigger muscle contractions. An EMG converts these impulses into graphs, noises, or numerical values that are subsequently evaluated by an expert using tiny apparatuses called electrodes.

A needle electrode is placed into a muscle during a needle EMG to record the electrical activity of that muscle.

The nerve conduction study, a component of an EMG, measures the speed and strength of impulses moving between two or more sites using electrode stickers attached to the skin (surface electrodes).

Your doctor might recommend an EMG if you exhibit any indications or symptoms pointing to a nerve or muscle tissue. Such signs might consist of the following:

• Tingling 

• Numbness

• Muscle tremor

• Cramping or aching muscles

• Some forms of limb discomfort

A low-risk procedure, EMG rarely has problems. Where a needle electrode is implanted, there is a slight possibility of bleeding, infection, and nerve damage.

There is a slight chance that air could seep into the space between the lungs and chest wall during a needle electrode examination of the muscles along the chest wall, leading to lung collapse. (pneumothorax).

The BERA hearing test is an electrophysiological test method that aids in locating and analysing the electrical potential produced at various levels of the auditory system, starting from the cochlea to the cortex. BERA is the most accurate and sensitive method for detecting lesions in the brainstem's VIII nerve and auditory pathway, especially in adults. 

Although numerous pure tones and impedance audiometric tests are specifically created to distinguish between cochlear and retrocochlear hearing loss, BERA is the most sensitive method. It is also the most affordable way to diagnose retro cochlear lesions and is non-invasive, simple to record, and unaffected by age, drowsiness, or anaesthesia.

The most affordable way to diagnose retro cochlear abnormalities is non-invasive, easily recordable, unaffected by age, drowsiness, or anaesthesia.

Additionally, pure tone audiometric examinations on children are frequently impractical, but BERA offers a quick and effective technique to check for deafness in newborns. As one of the most crucial objective techniques for assessing the peripheral auditory system in neonates, infants, sedated and comatose patients, as well as other non-linguistic individuals, this hearing test is the most precise and sensitive test for brain stem pathology.

When it comes to several things, healthy hearing is crucial. However, normal hearing comprises the auditory nerve, which can quickly send sound impulses from the ear to the brain. Under the right guidance of our specialists, this BERA test at our Asha Speech and Hearing clinics can reveal if nerves transmit sound impulses to the brain and whether the pace of sound delivery is within normal bounds.

The kind of defect (conductive or sensorimotor), severity (hearing threshold), and location of the child's hearing loss (inner ear or other regions) can all be identified by the specialists using the results of this hearing test.

Heritage Hospitals should be your first choice if you or someone close is advised for a BERA test in Varanasi. With our trained staff and the latest diagnostic aids, we strive to provide the best results.

The electrical signal that your visual cortex, a part of your brain, produces in response to visual stimulus is measured by a Visual Evoked Potential (VEP) test. It is also known as a visual evoked response test. (VER).

A VEP test precisely evaluates the performance of your visual pathway, which comprises your:

• Eyes.

• Eye nerves.

• Ocular chiasm (the place in your brain where some of the optic nerve fibres coming from one eye cross optic nerve fibres from the other eye).

• Optic nerve (the pathway between the optic chiasm and your brain).

• Optical radiance (the part of your visual pathway that transmits visual input coming from your retina, optic nerve and optic tract).

• Brain cortex.

Any issue that impacts your brain's visual cortex or pathways may appear abnormal on the VEP test.

Tests for visually evoked potentials can be used to identify or help diagnose the following conditions:

• Multiple Sclerosis

• Glioma

• Brain Trauma

• Hydrocephalus

• Toxic Optic Neuropathy

• Other types of Optic Neuropathy

• Infection-related problems with the visual system, such as meningeal TB.

Heritage Hospitals should be your first choice if you or someone close is advised for a VEP test in Varanasi. With our trained staff and the latest diagnostic aids, we strive to provide the best results.

Nerve dysfunction and injury are evaluated using a Nerve Conduction Velocity (NCV) test. The test, sometimes called a nerve conduction study, gauges the speed at which electrical signals pass through your peripheral nerves.

Where the nerve root emerges from the spinal cord is where your peripheral nerves begin. You can move your muscles and use your senses thanks to these nerves. Electrical signals are sent more swiftly and forcefully by healthy nerves than by damaged nerves.

Your doctor can distinguish between damage to the myelin sheath, the nerve's protective coating, and damage to the nerve fibre with the aid of the NCV test. Additionally, it can assist your doctor in determining if a condition is caused by a nerve injury that has impacted the muscles or a disorder of the nerves.

For a proper diagnosis and choosing your treatment plan, it's crucial to make these distinctions.

Numerous muscle and neuromuscular conditions, including the following, can be identified using an NCV test:

• The syndrome of Guillain-Barré

• Palmar-plantar syndrome

• Cuneiform tunnel syndrome

• The illness Charcot-Marie-Tooth (CMT)

• A disease of the herniated disc

• Neuropathy and chronic inflammatory polyneuropathy

• Issues with the sciatic nerve

• Damage to peripheral nerves

• Musculoskeletal injuries

Your doctor might advise an NCV test if they think you have a pinched nerve.

Along with an NCV test, an electromyography (EMG) test is frequently conducted. The electrical signals passing through your muscles are captured during an EMG exam. This aids in determining the existence, location, and severity of any illness that may harm the muscles and nerves.

Heritage Hospitals should be your first choice if you or someone close is advised for an NCV test in Varanasi. With our trained staff and the latest diagnostic aids, we strive to provide the best results.

When you have symptoms of muscle exhaustion, an RNST test is administered. It frequently identifies neuromuscular junction illnesses, including Lambert-Eaton Myasthenic Syndrome (LEMS) and Myasthenia Gravis (MG).

An electrode for recording will be put on the tested muscle to capture the nerve response to repeated electrical shocks. Between each round of electrical stimulation, you can be asked to exercise the muscle being evaluated for a few seconds to several minutes. Depending on your symptoms, several muscles and nerves may be checked.

The RNS (Repetitive Nerve Stimulation) Test is used to diagnose and assess symptoms, including-

• Insufficiency & Fatigability

• Ptosis (Drooping of eyelids)

• Diplopia (Double vision)

• Dysphagia (Difficulty in swallowing)

• Dysarthria (Slurred speech)

Heritage Hospitals should be your first choice if you or someone close is advised for an RNST test in Varanasi. With our trained staff and the latest diagnostic aids, we strive to provide the best results.

An image of your retina is created using the imaging technique known as optical coherence tomography, or OCT. By detecting the amount of a faint red light that bounces off your retina and optic nerve, the non-invasive technique creates an image. You can determine the thickness of your retina and optic nerve using optical coherence tomography.

During cardiac catheterisation, heart and vascular medicine medical professionals use optical coherence tomography to create images of your blood vessels. OCT imaging is also being used increasingly frequently by medical professionals in the domains of dentistry, gastroenterology, pulmonology, dermatology, and oncology.

The term "traditional angiography," also known as "arteriography," describes employing X-rays to look within blood arteries. Usually, your doctor will inject a radiopaque dye that is visible on X-rays. Eye care specialists also use a specific form of angiography to look at the blood vessels in your retina. When exposed to blue light, the dye employed glows.

Optical coherence tomography angiography is another tool that eye care specialists might use to examine your eye's blood vessels. The test is entirely noninvasive and does not require the injection of a dye, in contrast to conventional angiography.

Medical professionals use OCT to identify and treat several eye disorders, including:

• Glaucoma

• Age-related muscular degeneration

• Macular Pucker

• Diabetes-related Retinopathy

• Macular Hole

• Cystoid Macular Edema

Heritage Hospitals should be your first choice if you or someone close is advised for an OCT Scan in Varanasi. With our trained staff and the latest diagnostic aids, we strive to provide the best results.

An eye care professional may administer a visual field test, also called a Perimetry test, to you to help them identify or track various eye disorders. It is a quick and painless procedure.

An objective field test looks at two things:

• How far (while gazing straight ahead) up, down, left, and right can your eye see without moving?

• The term "visual field" refers to the total area you can see and describes how sensitive your vision is in various areas of the visual field.

Normally, a large portion of the area in front of you is visible to your eyes. Without shifting your gaze, you can see some of what is above, below, and to either side in addition to what is directly in front of you. The term "peripheral vision" refers to the entirety of the visible space that is not directly in front of you. This encircles the region immediately in front of you and is visible. (central vision).

You presumably turn your eyes toward the objects you want to see more clearly because vision is normally best in the centre of the visual field. The less you can see an object, the further it is from your vision centre. When something moves far enough to the side, it vanishes from your field of vision.

A routine eye examination includes a visual field test when you visit an optometrist or ophthalmologist. Your eye doctor can use visual field testing to look for early indications of conditions like glaucoma that gradually impair vision. Some glaucoma patients report no vision issues, although the visual field test reveals a loss of peripheral vision.

Your doctor can learn more about the area of your nervous system that controls your vision by having you take a visual field exam. Your nervous system's visual portion consists of the following:

• Your retina, which functions as a sort of interpreter in your eye, converts light energy into an electrical signal.

• Your optic nerve sends messages to your brain to be converted into images.

• Your brain is where signals are transformed into the pictures you view.

Your visual field may alter if any component of this system has problems. The test findings show well-known patterns that aid medical professionals in identifying particular kinds of illness or injury.
