Quick answer
The Hepatitis A Total Antibody Test costs ₹2,000 at Live Line Health Care. Measures all antibodies to hepatitis A, mainly to show whether you are already immune from past infection or vaccination, or still need the vaccine. No fasting is needed. It uses a blood sample and the report is usually ready within 24–48 hours.
Also known as: Anti-HAV Total, HAV Total Antibody, Hepatitis A IgG, Hepatitis A Immunity Test, HAV Antibody Total, Hepatitis A Antibody
What is the Hepatitis A Total Antibody Test?
The Hepatitis A Total Antibody test measures all antibodies your body has made against the hepatitis A virus, IgG and IgM together. IgG antibodies form after infection or vaccination and usually last for life, so this test mainly answers one practical question: are you already protected against hepatitis A? A reactive result means you have antibodies, most often from an infection you may never have noticed as a child, or from the hepatitis A vaccine.
This is not the right test for a person who has jaundice today. Because IgG persists for decades, a reactive total antibody cannot separate an illness this week from one thirty years ago. For a current illness, doctors use the Hepatitis A IgM test, which picks up only the early antibody. The total antibody test is more useful before vaccination, since people who are already immune do not need the vaccine. It is also useful for adults with chronic liver disease, for whom hepatitis A can be more serious, and for some travellers and workers. Childhood exposure has long been common in India, so many adults test reactive.
What it measures: Combined IgG and IgM antibodies to the hepatitis A virus, a marker of immunity or past infection.
Parameters included (1)
- Anti-HAV Total Antibody (IgG and IgM)
Why is this test done?
- Deciding whether hepatitis A vaccination is needed
- Checking immunity in people with chronic liver disease, including hepatitis B or C or fatty liver
- Before working as a food handler, health worker or child-care worker, when required
- Checking immunity after the hepatitis A vaccine in special situations, on a doctor’s advice
- Confirming past exposure as part of a wider liver assessment
When should you get tested?
- Usually done without any symptoms, as a check of immunity
- A planned vaccination where the doctor wants to know if it is needed
- Chronic liver disease, where protection from hepatitis A matters more
- A close contact of someone with hepatitis A, when a doctor wants to know if you are protected
How to prepare for the Hepatitis A Total Antibody Test
- 1Fasting is not needed for this antibody test.
- 2Note how many hepatitis A vaccine doses you have had and when.
- 3If you currently have jaundice, ask your doctor whether the IgM test is more suitable for you.
- 4Mention any recent blood transfusion or immunoglobulin injection, as these can carry antibodies from donors for a while.
Hepatitis A Total Antibody Test normal range
| Parameter | Typical reference range |
|---|---|
| Reactive | Antibodies present: immunity from past infection or vaccination |
| Non-reactive | No antibodies detected: not immune, and vaccination may be advised |
There is no single expected result here. A reactive test is a good outcome when checking immunity. It cannot show when an infection happened. Ranges are typical adult values and vary between labs, age and sex. Always use the range printed on your report and discuss results with your doctor.
Understanding your results
- A reactive result generally means lifelong protection, so the vaccine is usually not needed.
- A non-reactive result means you have not been infected or vaccinated. Discuss vaccination with your doctor, especially if you have liver disease.
- If you are unwell with jaundice, a reactive total antibody alone does not prove hepatitis A is the cause. An IgM test is needed.
- Being immune to hepatitis A gives no protection against hepatitis B, C or E, which are different viruses.
Hepatitis A Total Antibody Test – FAQs
What is the price of the Hepatitis A Total Antibody Test?
The Hepatitis A Total Antibody Test costs ₹2,000 at Live Line Health Care, at all 45 centres and for home sample collection.
What does hepatitis A total antibody reactive mean?
It means your body has antibodies to hepatitis A, either from an earlier infection or from vaccination. In most cases this means you are immune and cannot catch hepatitis A again. It does not, by itself, show a current illness.
Should I take this test if I have jaundice?
Usually not as the main test. A total antibody result is often reactive in adults from childhood exposure, so it cannot show whether hepatitis A is causing jaundice now. Doctors use the hepatitis A IgM test to check for a current infection.
Do I need the hepatitis A vaccine if my total antibody is reactive?
Generally no. A reactive result shows you already have protection, either from past infection or from vaccination. Your doctor will confirm this, particularly if you have recently had blood products or have other health conditions.
Why test for hepatitis A immunity before vaccination?
Many adults in India were infected as children and are already immune. Testing first can save an unneeded vaccine. Doctors may skip the test and vaccinate directly in some situations, so follow their advice on which approach suits you.
Who benefits most from knowing their hepatitis A immunity?
People with chronic liver disease, because hepatitis A can be more severe for them. Others include food handlers, health and child-care workers, and travellers. A non-reactive result helps your doctor decide whether to recommend vaccination.
Where can I get the Hepatitis A Total Antibody Test done?
