Clinical Chemistry, Immunoassays & ELISA

Clinical chemistry (also known as chemical pathology, clinical biochemistry or medical biochemistry) is concerned with analyzing bodily fluids for diagnostic and therapeutic purposes. The most common specimens tested in clinical chemistry are blood and urine. Many different tests exist in clinical chemistry to evaluate various chemical components including, but not limited to: glucose, electrolytes, enzymes, hormones, lipids (fats), proteins and other metabolic substances.
Immunoassays are a bioanalytical method that measures the presence or concentration of analytes such as hormones and infectious markers through an antibody or an antigen as a biorecognition agent. ELISA stands for Enzyme-Linked Immunosorbent Assay, used to detect and measure antibodies in autoimmune diseases, infective diseases, and allergies. Our department of clinical chemistry and immunoassays is equipped with world-class instruments from Roche, Abbott, Siemens, Biorad, Biomeriux & Sebia, capable of handling large volumes of various diagnostic tests with maximum precision and accuracy. Our department was also the first in the country to install the Roche Cobas 8000 analyzer with its capacity to perform 2200 chemistry and 470 Immunoassays per hour. The department uses fully automated ELISA analyzers like Evolis from Biorad and Chorus Trio from Disse Diagnostics. In addition, our allergy testing is processed on the PHADIA 250, which allows for rapid testing for a wide variety of allergens. We have highly efficient, experienced technical staff to perform the tests with utmost expertise and care along with this cutting-edge technology. We follow stringent processes and six sigma applications to ensure quality for accurate, complete and timely reports.

Hematology & Coagulation Studies

We perform a wide variety of basic and advanced hematology and coagulation testing. Hematology is the study of blood in health and disease. It includes recognizing abnormalities in red blood cells, white blood cells, platelets, blood vessels, bone marrow, lymph nodes and spleen. Coagulation studies deal with diagnosing and monitoring diseases associated with the proteins involved in bleeding and clotting (hemostasis and thrombosis).
Our hematology department is resourced with the HELO system, an efficient, innovative design solution covering all high throughput automated hematology platform needs. The HELO system comprises of:

Yumizen H1500/ H2500 - High throughput analyzer (120 samples per hour) capable of enumerating nRBCS separately along with immature cell fractions of WBCs, measuring platelets optically (optical extinction technology) & performing automated reticulocyte counts.
Yumizen T6000 - Automated conveyor
Yumizen P8000 - Middleware and expert validation station
Yumizen SPS - Automatic slide maker (smear and stain)
Cellavision DM9600 - Digital Cell Morphology System automatically performs blood & body fluid differentials with a maximum capacity of 20 slides/hour, enabling our department to work smarter, faster and perform better.

Our coagulation testing platform consists of the automated ACL Elite Pro system, enabling minimal turnaround time for the Hemostasis testing.
Inflammatory markers like ESR are measured on the Vision Pro automated ESR analyzer that holds Five Patents (USA, Germany, Italy, Turkey, China) & shows the best correlation with the Westergren method. Immunophenotyping is performed on the DxFLEX Flow Cytometer, which is designed for clinical testing. Under the leadership of one of the country’s best hemato-pathologists, Dr. Amar Dasgupta, we offer all types of flow cytometry panels enabling quick and accurate diagnosis in hematological and hemato-oncological diseases.

The department is equipped with fully automated Flow cytometry-based SYSMEX UF500, the Cobas U411, and a team of highly trained, experienced and dedicated technical staff that makes sure that accurate and complete reports are delivered on time.

Histopathology & Cytopathology

Histopathology deals with the gross and microscopic study of diseased tissue, along with any ancillary tests which may be needed for diagnosis or prognostication. Cytopathology is a sister science to histopathology and deals with the microscopic study of free cells or tissue fragments.
Our histopathology and cytopathology departments use the latest diagnostic techniques like immunohistochemistry, immunofluorescence, along with good old fashioned expert microscopy to provide accurate diagnosis and prognostic information from submitted tissue and body fluid samples. The department has gained a reputation for preparing excellent paraffin-embedded hematoxylin and eosin-stained sections and special stained sections. The lab processes more than 45,000 paraffin-embedded tissue blocks per year and more than 5 lakh slides!
A wide range of specimens is handled in the laboratory, including bone marrow biopsies, surgical oncology resections and biopsies, dermatology biopsies, outside blocks sent in consultation, renal biopsies and many more.


Our microbiology labs help diagnose and treat infectious diseases by rapidly and accurately identifying the organisms responsible.
We boast of a well-equipped microbiology lab with the latest cutting-edge technology. In addition, we have ensured that we apply automation in microbiology testing methods to ensure that human error is minimized and test reporting is expedited.
We use state-of-the-art technology with US FDA-approved instruments like BacT/ALERT, Vitek 2 Compact, MGIT Bactec, GeneXpert. Separate areas are marked out for processing bacteria, TB & fungus samples. In addition, we use updated CLSI guidelines used to interpret the sensitivity of reports. Our TB Lab is NTEP accredited for 1st line drug testing, and we offer a comprehensive range of TB tests.

We also provide testing options to assist hospitals and other health care institutions – such as OT sterility testing, MRSA screening etc. (hospital infection control). Our potable water testing for coliform bacteria is also widely used to test water sources used for consumption or daily use.
We are a national leader in fungal testing, being the only private laboratory in India to perform fungal drug sensitivity for dermatophytes (fungal infections of the skin, hair and nails). This being in addition to performing fungal culture on a wide variety of samples.


Serology is the study and diagnostic identification of antibodies in the serum. Such antibodies are typically formed in response to an infection, against other foreign proteins, or to one’s proteins.
The department of serology and immunology caters to the testing of vast volumes of samples for seasonal infectious disorders and supports this workload through its complete spectrum of serological markers. Tests for sexually transmitted diseases, dengue, chikungunya, malaria, leptospirosis and typhoid, and full automation in blood grouping, direct & indirect Coombs tests are some of the critical areas in our range of serological testing. We have a fully automated state of the art analyzer based on Column Agglutination Technology - Ortho Autovue from Johnson & Johnson for automated blood grouping.

Digital X-Ray

At Suburban Diagnostics, we offer digital X-ray facilities that are environment friendly and accredited by the Atomic Energy Regulatory Board (AERB). Digital X-rays are safer as compared to traditional X-rays as they reduce the amount of radiation that the patient is exposed to and also makes it simpler and easier to transfer, share and enhance images. They can be used for all routine X-rays as well as in specialized imaging studies like IVP (Intravenous Pyelogram).

X-rays done at Suburban Diagnostics:

  • Abdomen
  • Chest
  • Adenoids
  • Extremities
  • Joints
  • Kidney
  • PNS
  • Spine AP/Lateral


Suburban Diagnostics offers a complete range of ultrasonographic procedures like:


All sonography procedures at Suburban Diagnostics are strictly in compliance with PCPNDT laws and we strongly discourage and oppose the practice of sex determination of the foetus.

Obstetric Sonography

This procedure is generally used to understand and examine the following in pregnancy:

  • Routine obstetrics (growth scan, early pregnancy, assessment of cervical length, placental position)
  • Nuchal scan/NT scan/early anomaly scan
  • Second-trimester anomaly scan/targetted scan/malformation scan
  • Fetal echocardiography
  • Obstetric doppler
  • Biophysical profile

Early pregnancy

USG is done in early pregnancy to confirm the pregnancy as well as its position (intrauterine or extra-uterine). A gestational sac can be reliably seen on transvaginal ultrasound by 5 weeks’ gestational age (approximately 3 weeks after ovulation).

First Trimester

In the first trimester, a standard ultrasound examination typically includes:

  • Gestational sac size, location, and number
  • Identification of the embryo and/or yolk sac
  • Measurement of fetal length (known as the crown-rump length)
  • Fetal number, including the number of amniotic sacs and chorionic sacs for multiple gestations

Second and Third Trimester

In the second and third trimester, a standard ultrasound examination typically includes:

  • Evaluation of the maternal uterus, tubes, ovaries, and surrounding structures when appropriate
  • Ultrasonography of the cervix
  • Fetal number, including the number of amniotic sacs and chorionic sacs for multiple gestations
  • Fetal cardiac activity
  • Fetal position relative to the uterus and cervix
  • Amniotic fluid volume
  • Location and appearance of the placenta, including the site of umbilical cord insertion when possible
  • Gestational age assessment
  • Fetal weight estimation
  • Fetal anatomical survey

Obstetric sonography has become useful in the assessment of the cervix in women at risk for premature birth. A short cervix preterm is undesirable. At 24 weeks’ gestation a cervix length of less than 25 mm defines a risk group for preterm birth, further, the shorter the cervix the greater the risk. It also has been helpful to use ultrasonography in women with preterm contractions, as those whose cervix length exceeds 30 mm are unlikely to deliver within the next week.

Non-Obstetric / Gynec Sonography

We perform ultrasound imaging which uses sound waves to produce pictures of :

  • USG pelvis
  • Follicular monitoring / ovulation studies
  • AFC count
  • Pelvis Doppler

Routine sonography

Routine sonography is suggested for the various organs as following:

  • Whole abdomen / abdomen and pelvis
  • Detailed ultrasound assessment of all abdominal organs including liver, gall bladder, pancreas, spleen, kidneys, bladder, prostate and intestines
  • Upper abdomen
  • Detailed ultrasound assessment of all abdominal organs including liver, gall bladder, pancreas, spleen, kidneys, bladder
  • Kidney, ureter and bladder (KUB)
  • Detailed ultrasound assessment with specific focus on organs of urinary system including kidneys, bladder, prostate (in males) and uterus/ovaries (in females) with assessment of prevoid capacity of bladder and postvoid residue
  • Transrectal Ultrasonography (TRUS)
  • Also known as Transrectal Ultrasonography of the prostate, this is a detailed evaluation of prostate through a transrectal approach. In this procedure an ultrasonography probe is introduced per rectally for better understanding of the prostate sonomorphology and to rule out any suspicious lesions in the prostate
  • Inguinal regions
  • High resolution USG is done to rule out hernias or any other pathology in the inguinal regions
  • Scrotum
  • Detailed ultrasound assessment of the testis
  • Neck / Thyroid
  • Detailed ultrasound assessment of the thyroid gland, submandibular, parotid glands as well as to confirm/rule out the presence of any enlarged cervical lymph nodes
  • Sonomammography / USG Breast
  • USG Penis
  • Small parts / Soft tissue Sonography

  • Shoulder
  • Elbow
  • Wrist
  • Hip
  • Knee
  • Ankle
  • Foot
  • Tendo-achilles

Musculoskeletal USG is safe, noninvasive, and does not use ionizing radiation. This procedure requires little to no special preparation.


Mammography is a specialized medical technique that uses a low dose X-ray system to look inside the breasts. A Mammogram aids in early detection and diagnosis of breast diseases. One of the most recent advancements in Mammography is Digital Mammography, also known as Full-Field Digital Mammography (FFDM), uses same systems as a Digital Camera and their efficiency enables better pictures with an even lower radiation dose. These images are transferable by computer and are apt for long-term storage. Patient’s experience during a Digital Mammogram is similar to having a conventional film mammogram.

How should patients prepare for the mammogram?

Before scheduling a mammogram, the American Cancer Society (ACS) and other specialty organizations recommend that patients discuss any new findings or problems in breasts with their doctor. In addition, the patient should inform their physician of any prior surgeries, hormone use, and family or personal history of breast cancer. It is recommended that patients do not schedule their mammogram for the week before their menstrual period as breasts are usually tender during this time. The best time for a mammogram is one week following the period. The doctor should always inform the technologist if there is any possibility of their patient being pregnant.

How should patients prepare for the mammogram
Radiology Tests

The ACS also recommends that:

  • The patient should not wear deodorant, talcum powder or lotion under their arms or on the breasts on the day of the exam. These can appear on the mammogram as calcium spots.
  • The patients should describe any breast symptoms or problems to the technologist performing the exam.
  • Patients should obtain their prior mammograms and make them available to the radiologist if they were done at a different location. This is needed for comparison with your current exam and can often be obtained on a CD.

Bone Mineral Density (BMD)

Osteoporosis is a silent disease that can’t be detected until it reaches an advanced symptomatic stage or causes accidental fractures. Hence, regularly monitoring patients for their bone density is the only way a clinician can diagnose osteopenia (low bone mass) or osteoporosis at an early stage. After this, he can exercise remedial measures. A bone mineral density test is an easy, reliable test that measures the density or thickness of bones, using Dual X-ray Absorptiometry (DEXA) of the hip and spine, as preferred areas of measurement.

BMD test results are estimated on the basis of:


  • It’s the patient’s bone mineral density as compared to the peak bone mass in a normal young adult.
  • A score of 0 means BMD = normal of a healthy young adult.
  • The diagnosis of osteoporosis or low bone mass is based on the T-score.


  • It’s the patient’s bone mineral density as compared to the peak bone mass in an age-sex matched adult.
  • Z-SCORE is useful for determining whether an underlying disease or condition is causing bone loss.
BMD Tests
Instructions to Patients for BMD

Instructions to Patients for BMD:

  • Patients should avoid calcium supplements and multivitamins 24-48 hours prior to the test.
  • Clothes with metal buttons or buckles should be avoided.
  • Any jewellery or metal which may interfere with the test will have to be removed.

Colour Doppler Ultrasound Test

Suburban Diagnostics offers a range of Colour Doppler test procedures, like:

  • Abdominal
  • Carotid
  • Gravid Uterus
  • Renal
  • Single Limb Doppler (Arterial and Venous)
  • Dual Limb Doppler (Arterial and Venous)

Instructions to Patients for the Colour Doppler Test:

  • Generally, no prior preparation is required.
  • Patients should carry their prescription and any previous report they may have on the day of the test.
  • Any other instructions necessary for the test can be given when the appointment is booked.
Instructions to Patients for the Colour Doppler Test

Orthopantomography (OPG)

At Suburban Diagnostics, we have a state-of-the-art, specially-assembled OPG machine that rotates around the jawbones, giving us a comprehensive idea about the structure of the jawbones.

No special preparation is required for the test.

ECG (Electrocardiogram)

At Suburban Diagnostics, ECGs are conducted by trained technicians. These are then reviewed by a specialist physician/cardiologist to check for any signs of a potential problem.

An electrocardiogram is a painless, non-invasive way to diagnose many many of the common heart problems:

  • Irregularities in heart rhythm (Arrhythmia)
  • Heart defects
  • Problems with the heart’s valves
  • Blocked or narrowed arteries in the heart (Coronary Artery disease)
  • A heart attack emergency
  • A previous heart attack

How to Prepare?

No special preparations are necessary. However, avoid exercising right before an electrocardiogram. Physical activity, such as climbing stairs, etc. may increase your heart rate. An electrocardiogram is a safe procedure. There may be minor discomfort when the electrodes are taped to your chest. Although this happens rarely, a reaction to the electrodes may cause redness or swelling of the skin. There isn’t any risk during an electrocardiogram. The electrodes placed on your body only record the electrical activity of your heart. They don’t emit electricity.

Stress Tests

Stress test is also known as an Exercise test or Treadmill test.

Understanding the purpose of the individual exercise test allows the physician/cardiologist to determine the appropriate methodology and to select test endpoints that maximize test safety and obtain needed diagnostic and prognostic information.

It is used widely for the following:

  • Detection of Coronary Artery disease (CAD)
  • Evaluation of the functional severity of CAD
  • Prediction of cardiovascular events
  • Evaluation of exercise-related symptoms
  • Evaluation of physical capacity and effort tolerance
  • A heart attack, in emergency situations
  • Assessment of Chronotropic and Inotropic competence and Arrhythmias
  • Assessment of the response to medical interventions
Cardiology Test 1

Preparations for testing include the following:

  • The purpose of the test should be clear in advance to maximize diagnostic value and ensure safety.
  • The subject or patient should not eat a heavy meal in the 3 hours leading up to the test. Routine medications may be taken with small amounts of water. Subjects should dress in comfortable clothing and wear comfortable walking shoes or sneakers.
  • When exercise testing is performed for the diagnosis of ischemia, routine medication may be withheld because some drugs (especially beta-blockers) attenuate the HR and blood pressure responses to exercise.

How is the test performed?

  • A Stress Test is done under the supervision of a trained physician or a cardiologist. After initial screening, history, and examination, consent is taken and an appropriate protocol for the test is selected. The technician then Prepares the subject’s skin and attaches electrodes on his/her chest. These electrodes are attached to an ECG monitor.
  • A resting supine standard 12-lead ECG should be obtained before exercise, followed by standing and hyperventilation.
  • ECG and heart rate are recorded throughout the test. Blood pressure is also recorded at regular intervals.
  • After this, exercise is started on a treadmill with an initial warm-up period (at low workload), followed by progressive graded exercise with increasing loads and an adequate time interval in each level, and a post–maximum effort recovery period which is recorded.
Cardiology Test 2

2D Echo

2D Echocardiogram/Transthoracic Echocardiogram (Cardiac Ultrasonography).

At Suburban Diagnostics, this test is conducted only by trained physicians/cardiologists.

No special preparations are necessary for a standard transthoracic echocardiogram.

An echocardiogram uses sound waves to produce images of your heart.

Images from an echocardiogram 

The images from an echocardiogram help in identifying:

  • Heart murmurs
  • Ischaemic heart disease
  • Congenital heart disease
  • Native valve stenosis
  • Acute aortic dissection
