What is this test?

Hepatitis viral marker testing uses a blood sample to look for antigens or antibodies associated with hepatitis viruses. Depending on the panel, it may evaluate evidence of hepatitis A, B, C, or E infection.

Why might I need this test?

This testing may be ordered when symptoms suggest hepatitis, after contact with an infected person, during routine screening, or when monitoring liver disease. It can also help assess vaccination immunity when a hepatitis B marker is included.

How is the test performed?

A blood sample is analyzed in the laboratory using immunoassay or other laboratory methods. The report identifies each marker that was tested and whether its result is reactive, nonreactive, or requires another measurement.

How do I prepare for the test?

Usually no special preparation is required. Follow any instructions provided by your healthcare professional, particularly if other liver tests or hepatitis virus RNA testing have also been ordered.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

A reactive antigen result may indicate a current infection, while reactive antibodies may reflect recovery, a past infection, or immunity from vaccination. The meaning depends on the specific marker and the combination of results, so a clinician should interpret them together with symptoms, liver tests, and exposure history.

Short name

Frequently asked questions

Does a reactive result always mean I have hepatitis?
No. Some markers indicate current infection, while others show past infection or vaccination immunity. The specific marker and other results are needed for interpretation.
Can one blood test show which type of hepatitis I have?
A hepatitis panel includes separate tests for different viruses and markers. The report usually lists each result individually.
Do I need to avoid food or medication before this test?
Most hepatitis viral marker tests do not require fasting or medication changes. Follow the preparation instructions included with your lab order.
