Overview of the Hepatitis A Immunity (IgG/IgM) Test
The Hepatitis A Immunity (IgG/IgM) blood test assesses antibodies to Hepatitis A Virus, providing information about previous exposure or immunity.
The test contains 1 grouped biomarker: Hepatitis A Immunity (IgG/IgM).
Hepatitis A is a viral infection of the liver transmitted predominantly through the faecal-oral route.
Unlike Hepatitis B and C, Hepatitis A does not normally cause chronic infection.
After infection or successful vaccination, IgG antibodies can provide long-term immunity.
A total or grouped Hepatitis A antibody test may detect IgG and IgM-class antibodies together.
This makes it useful for determining whether antibodies to HAV are present, but the grouped result should not automatically be interpreted as proof of a recent infection.
For acute Hepatitis A, a specific Hepatitis A IgM test is more appropriate.
A positive immunity or total-antibody result can reflect previous infection, current infection or vaccination depending on the precise antibody pattern and clinical context.
Where acute illness is not suspected and IgM is negative, detectable IgG is compatible with immunity from previous infection or vaccination.
A negative result indicates that detectable Hepatitis A antibodies are absent and the person may be susceptible to infection if not appropriately vaccinated.
Testing can be useful before travel, when vaccination history is uncertain or where evidence of previous immunity is required.
What Does the Hepatitis A Immunity (IgG/IgM) Test Check?
The test assesses a grouped Hepatitis A antibody response that can provide information about previous exposure and immunity. This test measures 1 grouped biomarker.
Hepatitis A Immunity (IgG/IgM)
Assesses antibodies to Hepatitis A Virus to provide information about previous infection, vaccination-related immunity or, depending on the antibody pattern, possible recent exposure.
Who May Benefit From the Hepatitis A Immunity (IgG/IgM) Test?
Immunity testing may be useful when vaccination or previous infection history is unclear.
People unsure whether they are immune to Hepatitis A - Laboratory testing can identify whether HAV antibodies are present.
People with an uncertain vaccination history - Testing can provide evidence of previous immune exposure.
People preparing for travel to higher-risk areas - Immunity status may be relevant when considering vaccination.
People previously diagnosed with Hepatitis A - IgG antibodies generally persist after recovery.
People who believe they have previously been vaccinated - Antibody testing can provide additional information where documentation is unavailable.
People with occupational or clinical reasons to document Hepatitis A immunity - Laboratory evidence may occasionally be requested.
People with a previous equivocal Hepatitis A antibody result - Repeat testing can clarify whether antibodies are detectable.
How to Prepare
Do not delay clinically indicated vaccination solely to obtain immunity testing unless a healthcare professional has advised testing first.
Acute hepatitis symptoms require a different diagnostic approach from routine immunity assessment.
Symptoms and Reasons to Consider the Hepatitis A Immunity (IgG/IgM) Test
Immunity testing is usually performed without symptoms. Symptoms suggesting acute Hepatitis A should instead prompt specific IgM assessment and clinical review.
No symptoms but uncertain immunity - This is the most common reason to consider an immunity test.
Upcoming travel with unclear vaccination history - Knowing whether antibodies are present can support vaccination planning.
Previous Hepatitis A infection with incomplete records - Antibodies may remain detectable after recovery.
Previous vaccination without documentation - Testing may demonstrate an antibody response.
Jaundice or acute hepatitis symptoms - A specific Hepatitis A IgM test is more appropriate if recent infection is suspected.
A grouped or total Hepatitis A antibody result should not be used alone to diagnose acute Hepatitis A.
Acute illness requires clinical interpretation together with IgM anti-HAV and liver-function testing.

When Will I Receive My Results?
The expected laboratory turnaround for Hepatitis A Immunity (IgG/IgM) is approximately 1 business day after laboratory receipt.
Hepatitis A antibody measurement is an established serology test and can generally be processed quickly.
The sample undergoes laboratory analysis, quality-control checks and authorisation.
Turnaround begins from laboratory receipt rather than necessarily from the exact time the blood is collected.
If acute Hepatitis A is suspected, specific IgM testing and additional liver investigations may also be required.
Understanding Your Results
A negative result indicates that Hepatitis A antibodies were not detected at the laboratory threshold.
In a person without documented vaccination, this may indicate susceptibility to Hepatitis A.
A positive grouped or total-antibody result shows that antibodies to HAV are present.
This may reflect previous infection, current infection or vaccination.
Where the aim is specifically to determine immunity and there are no symptoms of acute hepatitis, IgG-type antibodies are the relevant marker of previous exposure or vaccine response.
If recent infection is suspected, a separate Hepatitis A IgM result is required because total antibody alone cannot reliably distinguish remote from recent exposure.
Results should therefore be interpreted with vaccination history and clinical circumstances.
