Hepatitis A/B/C Immunity Testing for Keyes Residents

What this test is

The Hepatitis A/B/C Immunity Testing is used to determine if an individual has immunity against hepatitis A and B viruses, or a current infection. It also helps identify past exposure to hepatitis C.

What it measures

• Anti-HAV IgG — reflects immunity to hepatitis A
• Anti-HBs — indicates immunity to hepatitis B
• Anti-HBc IgM — suggests recent hepatitis B infection
• Anti-HCV — shows exposure to hepatitis C

What the test involves

The test involves a standard blood draw, where a sample of blood is collected from a vein in your arm. This sample is then analyzed in a laboratory.

Why it is often ordered

Clinicians typically order this test to assess immunity status following vaccination or to check for past exposure to hepatitis viruses. It may also be ordered if symptoms suggest a possible hepatitis infection.

Preparation

Preparation may vary, so it is important to follow the specific instructions provided by the laboratory conducting the test.

How results are reported

Results are reported based on laboratory reference ranges, which can vary. They indicate whether immunity is present or if there has been past exposure.
