Overview
The primary purpose of the Hepatitis A Antibody (Anti-HAV) IgG Test is to determine whether a person has developed immunity to the hepatitis A virus. This test is used to assess past infection or verify immunity following hepatitis A vaccination. It helps healthcare providers evaluate immune status, guide vaccination decisions, and manage patients with liver disease or those at occupational risk. Unlike the IgM test which indicates acute or recent infection, a positive IgG result indicates either a resolved previous infection or successful immunization, suggesting the individual is protected against future hepatitis A infection. This test is also used in epidemiological studies to understand population-level immunity to hepatitis A.

Sample Collection
No special preparation or fasting is required for the Hepatitis A Antibody (Anti-HAV) IgG Test. Inform your healthcare provider about any medications, immunosuppressive therapies, or recent vaccinations before the test.
Method: Venipuncture
Laboratory Analysis
A trained phlebotomist will collect a blood sample from a vein in your arm using standard venipuncture technique. The procedure typically takes less than 5 minutes. You may feel a slight prick when the needle is inserted.
Report Delivery
After blood collection, pressure will be applied to the puncture site with a cotton ball or bandage. Mild bruising may occur at the site. You can resume normal activities immediately after sample collection.
Timeline: Results are typically available within 24 hours of sample collection. Reports can be accessed via the online portal, email, or WhatsApp.

Who Should Get This Test

This test is also used in epidemiological studies to understand population-level immunity to hepatitis A.
How to Prepare
- No fasting is required prior to sample collection
- Stay well hydrated before the blood draw
- Wear loose-fitting sleeves to allow easy access to the arm
- Inform the phlebotomist if you have a history of fainting during blood draws
- Apply pressure to the puncture site for 3-5 minutes after collection
- Avoid heavy lifting with the collection arm for a few hours after the test
Doctor's Notes
Reviewed by Dr Kothari Ramesh Shantilal — MBBS, MD (Microbiology) · Reg. No. 27670
"The Anti-HAV IgG test is a valuable marker for determining past infection or immunity following vaccination against Hepatitis A. A positive IgG result indicates either a resolved previous infection or successful immunization, both of which confer long-term protection. This test is particularly useful for individuals in high-risk groups such as healthcare workers, travellers to endemic regions, food handlers, and those with chronic liver disease who need to confirm their immunity status. It should not be confused with the IgM test, which indicates recent or active infection."

Test Parameters & Specifications
Sample Stability
- Incorrectly labelled or unlabelled samples
- Samples collected in wrong tube type (non-SST)
- Haemolysed, lipemic, or icteric samples beyond acceptable limits
- Samples received at room temperature beyond 2 hours of collection
- Insufficient sample volume (less than 1 mL serum)
Understanding Your Results
Non-reactive (< 1.0 S/CO)
Indicates no evidence of past infection or immunity to hepatitis A.
Reactive (≥ 1.0 S/CO)
Indicates immunity to hepatitis A. The individual is protected against future hepatitis A infection.
Equivocal (Borderline)
Cannot definitively determine immune status. Requires follow-up testing.
Consult your doctor if your test results show a non-reactive (negative) result and you are at risk of hepatitis A exposure, if your results are equivocal and require follow-up testing, if you are experiencing symptoms such as jaundice, dark urine, fatigue, nausea, vomiting, or abdominal pain, or if you have chronic liver disease and need to assess your hepatitis A immunity status. Your doctor will guide you on whether hepatitis A vaccination or further testing is needed.
Limitations
- ⚠This test detects IgG antibodies only and cannot distinguish between immunity from natural infection versus vaccination
- ⚠A negative result does not rule out very early hepatitis A infection where IgG has not yet developed; IgM testing is recommended for acute infection diagnosis
- ⚠Results should always be interpreted in conjunction with clinical findings, patient history, and other laboratory tests
- ⚠In immunocompromised patients, antibody levels may be lower than expected
Risks & Considerations
- ●Minor bruising or discomfort at the blood draw site
- ●Slight risk of infection at the puncture site (very rare)
- ●Fainting or lightheadedness during or after blood collection (uncommon)
Interfering Factors
- ●Immunosuppressive therapy or conditions may affect antibody production and lead to false-negative results
- ●Very early infection may not yet have produced detectable IgG levels (IgG typically appears after IgM)
- ●Cross-reactivity with other hepatitis viruses is uncommon but may rarely occur
- ●Haemolytic or lipemic serum samples may interfere with certain assay methods
