HBsAg
HBsAg (Hepatitis B surface antigen) – A “positive” or “reactive” HBsAg test result means that the person is infected with hepatitis B. This test can detect the actual presence of the hepatitis B virus (called the ?surface antigen?) in your blood. If a person tests ?positive,? then further testing is needed to determine if this is a new ?acute? infection or a ?chronic? hepatitis B infection. A positive HBsAg test result means that you are infected and can spread the hepatitis B virus to others through your blood.
anti-HBs or HBsAb (Hepatitis B surface antibody) – A “positive” or “reactive” anti-HBs (or HBsAb) test result indicates that a person is protected against the hepatitis B virus. This protection can be the result of receiving the hepatitis B vaccine or successfully recovering from a past hepatitis B infection. This test is not routinely included in blood bank screenings. A positive anti-HBs (or HBsAb) test result means you are ?immune? and protected against the hepatitis B virus and cannot be infected. You are not infected and cannot spread hepatitis B to others.
anti-HBc or HBcAb (Hepatitis B core antibody) – A “positive” or “reactive” anti-HBc (or HBcAb) test result indicates a past or current hepatitis B infection. The core antibody does not provide any protection against the hepatitis B virus (unlike the surface antibody described above). This test can only be fully understood by knowing the results of the first two tests (HBsAg and anti-HBs). A positive anti-HBc (or HBcAb) test result requires talking to your health care provider for a complete explanation of your hepatitis B status.₹358.00Add to cart -
HDL / LDL Ratio
DL cholesterol (HDL-C) is often known as ?good cholesterol? because it is associated with better cardiovascular health. In contrast, low-density lipoprotein (LDL) cholesterol is called ?bad cholesterol? because it is associated with cardiovascular disease.
HDL cholesterol is almost always measured along with total cholesterol, and these two measurements are core parts of the lipid panel test. A lipid panel is a common test measuring HDL cholesterol, total cholesterol, LDL cholesterol, and fat molecules called triglycerides.
The purpose of HDL cholesterol testing is to assess your cardiovascular health, including your risk for heart disease. HDL cholesterol is considered to be a good type of cholesterol that is associated with a lower risk of coronary heart disease events.
Measuring HDL cholesterol and total cholesterol together in the same blood sample allows the doctor to easily calculate the ratio of HDL cholesterol to non-HDL cholesterol. This is important for assessing your cardiovascular health and allows the doctor to understand the relative amounts of good and bad cholesterols.
Testing of HDL cholesterol can play a role in screening, monitoring, and diagnosing problems that affect your heart, blood vessels, and blood circulation.

Testing of HDL cholesterol can play a role in screening, monitoring, and diagnosing problems that affect your heart, blood vessels, and blood circulation.
Screening
Screening is looking for health problems before any symptoms have occurred. The goal of cardiovascular screening is to better address problems by finding them at an earlier stage.₹175.00Add to cart -
Hemoglobin
A hemoglobin test measures the amount of hemoglobin in your blood. Hemoglobin is a protein in your red blood cells that carries oxygen to your body’s organs and tissues and transports carbon dioxide from your organs and tissues back to your lungs.
If a hemoglobin test reveals that your hemoglobin level is lower than normal, it means you have a low red blood cell count (anemia). Anemia can have many different causes, including vitamin deficiencies, bleeding and chronic diseases.
If a hemoglobin test shows a higher than normal level, there are several potential causes ? the blood disorder polycythemia vera, living at a high altitude, smoking and dehydration.

Why it’s done
You may have a hemoglobin test for several reasons:To check your overall health. Your doctor may test your hemoglobin as part of a complete blood count during a routine medical examination to monitor your general health and to screen for a variety of disorders, such as anemia.
To diagnose a medical condition. Your doctor may suggest a hemoglobin test if you’re experiencing weakness, fatigue, shortness of breath or dizziness. These signs and symptoms may point to anemia or polycythemia vera. A hemoglobin test may help diagnose these or other medical conditions.
To monitor a medical condition. If you’ve been diagnosed with anemia or polycythemia vera, your doctor may use a hemoglobin test to monitor your condition and guide treatment.₹114.00Add to cart -

HIV Combo
here are three types of HIV tests: antibody tests, antigen/antibody tests, and nucleic acid tests (NAT). Antibodies are produced by your immune system when you?re exposed to viruses like HIV. Antigens are foreign substances that cause your immune system to activate. If you have HIV, an antigen called p24 is produced even before antibodies develop.
HIV tests are typically performed on blood or oral fluid. They may also be performed on urine.
Antibody Test

An antibody test looks for antibodies to HIV in your blood or oral fluid.Most rapid tests and the only HIV self-test approved by the U.S. Food and Drug Administration (FDA) are antibody tests.
In general, antibody tests that use blood from a vein can detect HIV sooner than tests done with blood from a finger stick or with oral fluid. How long will it take to get my HIV test results?
It depends on the type of HIV test and where you get tested.HIV self-tests provide results within 20 minutes.
With a rapid antibody test, usually done with blood from a finger stick or with oral fluid, results are ready in 30 minutes or less.
The rapid antigen/antibody test, done with blood from a finger stick, takes 30 minutes or less.
It may take several days to receive your test results with a NAT or antigen/antibody lab test.
Antigen/Antibody Test

An antigen/antibody test looks for both HIV antibodies and antigens.Antigen/antibody tests are recommended for testing done in labs and are common in the United States. This lab test involves drawing blood from a vein.
There is also a rapid antigen/antibody test available that is done with blood from a finger stick.
Nucleic Acid Test (NAT)

A NAT looks for the actual virus in the blood.With a NAT, the health care provider will draw blood from your vein and send the sample to a lab for testing.
This test can tell if a person has HIV or how much virus is present in the blood (HIV viral load test).
A NAT can detect HIV sooner than other types of tests.
This test should be considered for people who have had a recent exposure or a possible exposure and have early symptoms of HIV and who have tested negative with an antibody or antigen/antibody test.

HLA B27
HLA-B27 is a blood test to look for a protein that is found on the surface of white blood cells. The protein is called human leukocyte antigen B27 (HLA-B27).
Human leukocyte antigens (HLAs) are proteins that help the body’s immune system tell the difference between its own cells and foreign, harmful substances. They are made from instructions by inherited genes.

Homocysteine
A homocysteine test measures the amount of homocysteine in your blood. Homocysteine is a type of amino acid, a chemical your body uses to make proteins. Normally,?vitamin B12, vitamin B6, and?folic acid?break down homocysteine and change it into other substances your body needs. There should be very little homocysteine left in the bloodstream. If you have high levels of homocysteine in your blood, it may be a sign of a?vitamin?deficiency,?heart disease, or a rare?inherited disorder. A homocysteine test may be used to:
Find out if you have deficiency in vitamin B12, B6, or folic acid.
Help diagnose homocystinuria, a rare, inherited disorder that prevents the body from breaking down certain proteins. It can cause serious health problems and usually starts in early childhood. Most U.S. states require all infants to get a homocysteine blood test as part of routine newborn screening.

HSCRP
The level of C-reactive protein (CRP) increases when there’s inflammation in your body. A simple blood test can be done to check your C-reactive protein level.
A high-sensitivity C-reactive protein (hs-CRP) test is more sensitive than a standard CRP test. That means the high-sensitivity test can detect slight increases within the normal range of standard CRP levels. The hs-CRP test can be used to determine your risk of developing coronary artery disease, a condition in which the arteries of your heart are narrowed. Coronary artery disease can lead to a heart attack.
Why it’s done
Your doctor might order a CRP test to:Check for inflammation due to an infection
Help diagnose a chronic inflammatory disease, such as rheumatoid arthritis or lupus
Determine your risk of heart disease
Evaluate your risk of a second heart attack₹427.00Add to cart -
