Quick Facts
- Sample: Blood
- Fasting: No fasting required. Stop biotin consumption at least 72 hours prior to collection.
- Turnaround: 2-3 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
- Detects both IgM and IgG antibodies to hepatitis A virus
- Helps evaluate a possible current or past hepatitis A infection
- Helps assess whether you have immunity to hepatitis A
- Requires only a blood sample with no fasting needed
- Convenient online ordering with results delivered online
Who Is This Test For?
- Individuals experiencing symptoms of acute viral hepatitis
- People with abdominal pain, fatigue, or nausea and vomiting
- Individuals noticing yellowed skin or eyes, or dark urine
- People wanting to understand their hepatitis A antibody status
- Individuals wanting to discuss possible hepatitis A immunity with a provider

FAQ
1. What is the purpose of this test?
This test measures total Hepatitis A antibody, including both IgM and IgG, in your blood. The result may help a healthcare provider evaluate a possible hepatitis A infection or assess whether you have developed immunity to the virus. It is a single test focused on this one biomarker and does not provide a complete evaluation of liver function or other conditions.
2. Who would benefit from this test?
This test may be considered by individuals experiencing symptoms associated with acute viral hepatitis, such as abdominal pain, fatigue, nausea, vomiting, yellowed skin or eyes, or dark urine. It may also be of interest to individuals who want to understand their hepatitis A antibody status. This test is not intended to address every possible cause of these symptoms.
3. When should I order this test?
You may consider ordering this test if you are experiencing symptoms commonly associated with acute viral hepatitis, such as fatigue, nausea, joint pain, 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. This test does not replace a full medical evaluation.
4. What does this test measure?
This test measures total Hepatitis A antibody (Hep A Ab, Total) using a blood sample, detecting both IgM and IgG antibodies produced in response to hepatitis A virus exposure. It reflects your body's antibody response to the virus rather than directly measuring the virus itself or liver enzyme activity. The source does not specify additional biomarkers, and none are included in this test.
5. Do I need to fast before this test?
No fasting is required for this test. You should stop biotin consumption at least 72 hours prior to the blood collection.
6. How quickly will I get results?
Results are typically available in 2-3 days. Results may take longer based on weather, holidays, or lab delays.
7. How do I interpret the results?
The meaning of your Hepatitis A antibody result depends on your individual symptoms, medical history, prior vaccination status, and other laboratory findings. Antibody presence can reflect current infection, past infection, or immunity, and interpretation should account for these factors together rather than the result alone. A healthcare provider is best positioned to explain what your specific result means for you.
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.
8. What should I do if my results are abnormal?
If your results fall outside the expected range, review them with a qualified healthcare provider who can consider your symptoms and medical history. They can help determine whether additional evaluation is appropriate. Do not start, stop, or change any medication or treatment based on this result alone.
9. How often should I get tested?
There is no set testing schedule for this test in the source information. Testing frequency should be determined as directed by your healthcare provider, based on your individual health circumstances and any ongoing symptoms or concerns.
Pre test preparation
