Anti Hepatitis A (IgG)

The Anti-Hepatitis A IgG (Anti-HAV IgG) Test is a blood test used to detect IgG antibodies against the Hepatitis A Virus (HAV).

This test helps healthcare professionals determine whether a person has developed immunity to Hepatitis A through a previous infection or vaccination. Hepatitis A is a viral infection that primarily affects the liver and is commonly transmitted through contaminated food or water.

What Does This Test Check?

• Detects IgG antibodies against the Hepatitis A Virus (HAV).

• Helps determine immunity to Hepatitis A following previous infection or vaccination.

• Supports the assessment of past exposure to Hepatitis A.

• May help evaluate immune status in individuals at increased risk of Hepatitis A exposure.

• Assists healthcare professionals in assessing the need for Hepatitis A vaccination when clinically appropriate.

Sample Requirements

• Sample Type: Clotted Blood or Serum

• Required Quantity: 2–3 ml

• Department: Serology / Immunology (subject to laboratory confirmation).

Patient Preparation

• Fasting is generally not required for the Anti-Hepatitis A IgG Test.

• Inform your healthcare provider if you have previously received the Hepatitis A vaccine.

• Inform your doctor about any history of Hepatitis A infection or liver disease.

• Follow any specific sample collection instructions provided by the laboratory.

Important Information

The Anti-Hepatitis A IgG Test detects antibodies associated with immunity to Hepatitis A but is not used to diagnose an active or recent Hepatitis A infection.

A positive or reactive Anti-HAV IgG result generally indicates immunity due to previous Hepatitis A infection or vaccination.

A negative or non-reactive result indicates that Hepatitis A IgG antibodies were not detected and may suggest that the individual is not immune to Hepatitis A.

For suspected recent or acute Hepatitis A infection, the Anti-HAV IgM Test is generally used.

Results should be interpreted by a healthcare professional alongside vaccination history, symptoms, medical history, and other relevant investigations.

Reporting Time: To be confirmed by the laboratory.
