Quick Facts
- Sample: Blood
- Fasting: No fasting required. Stop biotin consumption at least 72 hours prior to collection.
- Turnaround: 2-3 business days. May take longer based on weather, holiday, or lab delays.
What This Test Measures
This test measures total Hepatitis A antibody (Hep A Ab, Total) in your blood, detecting both IgM and IgG antibodies produced in response to the hepatitis A virus. The presence of these antibodies can help a healthcare provider evaluate a possible hepatitis A infection or determine whether you have developed immunity to the virus.
This test reports on antibody presence rather than on liver function or viral genetic material. It does not measure other hepatitis viruses, liver enzymes, or additional biomarkers beyond total Hepatitis A antibody.
Benefits

FAQ
1. What is the purpose of this test?
This test measures total hepatitis A antibodies, including both IgM and IgG, in your blood. It may help a healthcare provider evaluate possible hepatitis A infection or assess whether you have developed immunity to the virus. It does not provide a complete evaluation of liver function or other conditions.
2. When might I consider ordering this test?
You may consider this test if you have symptoms associated with acute viral hepatitis, such as abdominal pain, fatigue, nausea, vomiting, joint pain, dark urine, or yellowing of the skin or eyes. It may also be useful if you want to check for prior exposure or immunity to hepatitis A.
3. What does this test measure?
This test measures total hepatitis A antibodies (Hep A Ab, Total) in a blood sample, detecting both IgM and IgG antibodies produced in response to hepatitis A virus exposure. It reflects your body’s antibody response rather than directly measuring the virus or liver enzyme activity.
4. Do I need to fast or prepare before this test?
Fasting is not required. Stop taking biotin at least 72 hours before your blood draw.
5. How quickly will I get results?
Results are typically available in 2–3 days. Weather, holidays, or laboratory delays may extend this timeframe.
6. How do I interpret the results?
Interpretation depends on your symptoms, medical history, vaccination status, and other laboratory findings. Antibody presence may reflect current infection, past infection, or immunity, so results should be considered together with these factors.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
7. What should I do if my result is outside the expected range?
Review your result with a qualified healthcare provider. They can assess it alongside your symptoms and medical history and determine whether additional evaluation is appropriate. Do not start, stop, or change medication or treatment based on this result alone.
8. How often should I get tested?
There is no set testing schedule in the provided information. Follow your healthcare provider’s guidance based on your health circumstances and any ongoing symptoms or concerns.
Pre test preparation
No fasting is required. Patient should stop biotin consumption at least 72 hours prior to the collection.
