State-of-the-Art Lab, Diagnostic & Imaging Services

Apollo Clinic offer comprehensive care and non-invasive diagnostic services for our patients with “Human Touch”. This includes consultation with one of our general physician as well as an ongoing evaluation and management of any specialized problem. Doctors rely on the accuracy of tests and other investigations to make their diagnosis. At Apollo Clinic we use state-of-the-art equipment, follow a set of stringent procedures and have the most qualified doctors and technical staff to ensure that every test result and investigation is accurate. Diagnostic facilities that can be availed at the clinic are:

State-of-the-Art Laboratory

A large number of laboratory tests are widely available to help doctors confirm their clinical findings and reach a diagnosis. Many tests are specialized for a particular group of diseases and a deviation from normal indicate that the organ is diseased. Apollo Clinic, State-of-the-Art

Laboratory equipped to handle investigations in the areas of:


It is the study of the chemical constituents of the human body in health and disease. Most tests are carried out on blood or urine but other body fluids, cells and tissues may also be analyzed. The Clinical Chemistry Laboratory performs a wide range of tests in order to determine the diagnosis of various conditions. Some of the common tests in biochemistry are:

      bullet    Blood Sugar
      bullet    Liver Function Test
      bullet    Lipid Profile
      bullet    Kidney Function Tests


Haematology is the study of blood and blood forming tissues. The techniques of haematology are concerned with the cellular formed elements of blood, their number or concentration, the relative distribution of various types of cells and the structure or biochemical abnormalities that promote disease such as anemia, haematological malignancy and coagulation abnormalities. Various tests in Haematology are.

      bullet     Complete Blood Count including TLC, DLC, etc.
      bullet     ESR


Laboratories are primarily concerned with providing a service to clinicians to aid in the diagnosis and treatment of microbial diseases such as meningitis, respiratory tract and disease of digestive system and wound infections. Specimens commonly examined are blood, urine, fasces and sputum.


It is the examination of any part of body for diagnostic purposes by means of x-rays, the record of the findings being impressed upon a photographic plate or film.

X – rays: X-rays are a form of radiation, like light or radio waves that can be focused into a beam, much like a flashlight beam. Unlike a beam of light, however, X –rays can pass through most objects, including the human body. When X-rays strike a piece of photographic film, they can produce a picture. Dense tissues in the body, such as bones, block (absorb) many of the X-rays and appear white on an X-ray picture. Less dense tissues, such as muscles and organs, block fewer of the X-rays (more of the X-rays pass through) and appear in shades of gray. X-rays that pass through air appear black.

X –ray is one of the fastest and easiest ways for a physician to view the internal organs and structures of the body. X-Ray is an excellent tool for assessing skeletal trauma (eg. Broken bones), for diagnosing the gastro-intestinal system (digestive tract) and for comprehensive imaging of the thoracic cavity including the lungs and heart.


Imaging is the process of production of images of organs or tissues using various procedures. We have state-of-the–art Imaging services available at Apollo clinics which include:

Ultrasound with Colour Doppler:

A Doppler ultrasound test uses reflected sound waves to evaluate blood as it flows through a blood vessel. It helps doctors evaluate blood flow through the major arteries and veins of the arms, legs, and neck. It can show blocked or reduced blood flow in the arteries of the neck that could cause a stroke. It can also reveal blood clots in leg veins that could break loose and block blood flow to the lungs (pulmonary embolism).

Colour Doppler can determine and display the direction and velocity of blood flow in the heart chambers and vessels. This equipment in Apollo clinic is used for Doppler ultrasound, echocardiography as well as for abdominal ultrasonography.

This test is done by a doctor who specializes in performing and understanding imaging tests (radiologist/sonologist) or by an ultrasound technologist.

Specialized Diagnostics

It is believed at Apollo Clinic that the first step to cure is accurate diagnosis of the disorder. Investment in the latest medical and diagnostic equipment along with upgradation of skills of personnel is always ensured.

Electrocardiogram (ECG)

A natural electrical system causes the heart muscle to contract and pump blood through the heart to the lungs and the rest of the body. Electrocardiography (ECG) is a test that records the electrical activity of the heart.

The electrical activity of the heart can be detected through the skin by small metal discs called electrodes. During electrocardiography, the electrodes are attached to the skin on the chest, arms, and legs. The electrodes are also connected to a machine that translates the electrical activity into line tracings on paper. These tracings are often analyzed by the machine and then carefully reviewed by a doctor for abnormalities.

An electrocardiogram may show:

      bullet     Evidence of heart enlargement.
      bullet     Signs of insufficient blood flow to the heart.
      bullet     Signs of a new or previous injury to the heart (heart attack).
      bullet     Heart rhythm problems (arrhythmias)
      bullet     Changes in the electrical activity of the heart caused by a chemical (electrolyte) imbalance in the body.

Electrocardiography (ECG) is usually done by a technician, and the resulting ECG is interpreted by a doctor who specializes in heart problems (Cardiologist) or a general physician.

Stress Echocardiography

Stress Echocardiography or Tread Mill Test helps to evaluate how the heart responds to the demands of physical activity and can detect some early changes, which may not be seen in the resting ECG.

Stress Echocardiography /TMT is done:


To evaluate unexplained but stable chest pain and determine its cause when Coronary Artery diseases is suspected.


To determine the severity of heart disease and the ability of the heart to tolerate exercise in people with known heart disease or those who have had a heart attack or heart surgery. On the basis of this information, a cardiac rehabilitation program, including appropriate exercise as well as a plan for low-risk daily physical activities, can be developed.


To identify abnormal heart rhythms when symptoms such as dizziness, fainting, or palpitations occur during exercise or activity.


To screen for CAD (Coronary Artery Disease) in a person without symptoms, especially if the person has risk factors for CAD.


After angioplasty, to see if arteries have renarrowed, especially if chest pain or other symptoms have returned.


To evaluate the effectiveness of certain medications or other therapy for irregular heartbeats or chest pain.

Chest X-ray

The chest X-ray is the most common type of X-ray test. Routinely taken from the back to the front, it can reveal certain abnormalities, which cannot be detected during physical examination. It provides a picture of organs and structures within the chest, including the heart and lungs, the blood vessels associated with them, and the thin sheet of muscle just below the lungs.

A chest X-ray can help detect problems with these structures and with the bones inside the chest, such as the ribs, clavicle (collarbone) and upper part of the spine.

A Chest X-ray is taken by a radiology technologist (radiographer). The X-ray pictures are usually interpreted by a doctor who specializes in evaluating X-ray (radiologist)

Pulmonary Function Test (PFT) / Lung Function Tests

Lung function tests evaluate how much air the lungs can hold, how quickly can a person move air in and out of the lungs, and how well lungs add oxygen to the blood and remove carbon dioxide from the blood.
