Hepatitis B Surface Antigen with Reflex Confirmation
Screens for the three most common causes of acute viral hepatitis when symptoms or exposure raise the question.
Consider this test if:
- New fever, fatigue, nausea, abdominal discomfort, dark urine, or jaundice
- A recent known or suspected exposure to hepatitis A, B, or C
- Sorting out the cause of unexplained abnormal liver enzymes
- Recent shared needles, unprotected sex, or travel to a high-prevalence area
- HSA/FSA eligible
- Results delivered to your dashboard · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Reflex testing
If the hepatitis B surface antigen or hepatitis C antibody screen falls outside the standard range, a confirmatory follow-up test runs automatically to verify the result and, for hepatitis C, confirm whether the infection is current. This is done at no additional cost.
Pre-test considerations
No fasting required, and timing during the day does not affect the result. If you have had a recent hepatitis A vaccination, note it, since hepatitis A IgM can reflect recent vaccination as well as infection.

What this test is for
This panel screens for acute or recent infection with hepatitis A, B, and C, the three viruses behind most viral hepatitis in the US. It checks hepatitis A IgM antibody, hepatitis B surface antigen (a marker of active, infectious HBV), hepatitis B core IgM antibody (a sign of recent HBV infection within the last 4 to 6 months), and hepatitis C antibody. These infections share symptoms including fever, fatigue, loss of appetite, nausea, abdominal discomfort, dark urine, pale stools, and jaundice, so this panel helps sort out which virus, if any, is responsible. A positive hepatitis C antibody does not by itself confirm current infection, which is why the reflex to HCV RNA matters: it distinguishes active infection from a resolved one or a false-positive screen. If your question is simply whether you carry chronic hepatitis B, the standalone hepatitis B surface antigen test is the narrower option; this panel is built for evaluating acute or recent infection across all three viruses.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost, covering the lab and what it takes to run the service. It is never a profit on the test itself. Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9 per month, and any applicable lab order or draw fee is itemized before you pay.
Where do I get tested?
Choose an available partner lab at checkout. If your cart contains multiple blood tests, Mito helps consolidate the eligible tests at one lab when possible. At-home kits and scans follow the collection or appointment process shown on their product page.
Is this eligible for HSA/FSA?
Yes. Eligible tests can be paid for with an HSA or FSA card at checkout.
When will I get my results?
Your results appear in your Mito dashboard after the laboratory completes processing. A clinician then reviews them before your analysis and personalized action plan are finalized. Timing varies by test, and specialty assays and at-home kits may take longer.
Do I need a physician's order?
No. Mito provides the laboratory order when one is required, so you do not need to arrange a separate physician visit before purchasing.
