Hepatitis A Profile

The Hepatitis A Profile is a straightforward blood test that helps determine whether you have a current or previous hepatitis A infection. It is suitable for anyone concerned about possible exposure to the virus, those experiencing symptoms such as fatigue, nausea, abdominal discomfort, or jaundice, and individuals who may be at increased risk through travel, occupational exposure, or close contact with an infected person. It is also useful for confirming immunity following vaccination or prior infection.

Hepatitis A is a viral infection that affects the liver. It is typically spread through contaminated food or water, or through close contact with someone who is infected. Many people recover fully without complications, but the infection can occasionally cause more serious liver problems, particularly in older adults or those with existing liver disease. Identifying whether an infection is recent or has occurred in the past helps guide appropriate clinical management and public health measures.

Markers included

Hepatitis A Antibodies
- Hepatitis A virus IgM antibody (HAV IgM): This marker is used to identify a recent or acute infection. It typically becomes detectable early in the illness and remains positive for several months.
- Hepatitis A virus total antibody (HAV Ab): This marker detects both IgM and IgG antibodies and provides a broader picture. A positive total antibody result with a negative IgM generally indicates past infection or successful vaccination, reflecting immunity.

Why it matters
Knowing your hepatitis A status can bring clarity and peace of mind. If you have symptoms, it helps confirm whether hepatitis A is the cause. If you have no symptoms but are unsure about your immunity, it can show whether you are protected. This information supports timely clinical decisions, helps prevent onward transmission, and allows you to discuss vaccination or other preventive steps with your doctor where appropriate.
