What's this test for?

This test is ideal if you've been exposed to Hepatitis B, work in healthcare, travel internationally, or want to check your liver health status. It detects Hepatitis B infection in its earliest stages, whether acute or chronic, and helps identify hidden risks before symptoms appear. Many people use this test after potential exposure, for routine screening, or when experiencing unexplained fatigue and liver-related symptoms.

How should I prepare for this test?

No biotin: 72 hours

If you're taking high-dose biotin supplements (also known as vitamin B7, B8, vitamin H, or coenzyme R), you should stop consumption at least 72 hours before your blood draw. Biotin can interfere with some tests in this panel and affect result accuracy. Otherwise, no special preparation is typically required for this test.

What's included in this test?

Hepatitis B Surface Antigen

This test measures Hepatitis B Surface Antigen (HBsAg), which is the earliest and most reliable indicator of active Hepatitis B infection. This antigen appears in your blood during both acute and chronic infections, making it essential for early detection and diagnosis. When present, it signals that the virus is actively replicating in your body and helps your doctor determine the stage and severity of infection.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your Hepatitis B status means for your liver health and overall wellbeing. These notes include personalized recommendations like follow-up testing, lifestyle modifications to support liver function, or whether you should consult with a hepatologist or infectious disease specialist. You'll also get the standard lab report and can track your status over time using our trends feature, which is especially helpful for monitoring chronic infections or confirming successful immunity.
Who should consider getting this test?
This test is important for healthcare workers, people with potential exposure through needlestick injuries or unprotected contact, international travelers to high-risk areas, and anyone with a sexual partner who has Hepatitis B. It's also recommended for pregnant women, people born in regions where Hepatitis B is common, injection drug users, and individuals living with someone who has Hepatitis B. If you're experiencing unexplained fatigue, jaundice, or abdominal pain, this test can help identify the cause.
What symptoms indicate I may need this test?
Early Hepatitis B infection may cause fatigue, loss of appetite, nausea, vomiting, abdominal pain, dark urine, or jaundice (yellowing of skin and eyes). However, many people have no symptoms at all, especially in the early stages or with chronic infection. If you've had potential exposure or fall into a higher-risk category, testing is important even without symptoms.
How can I naturally support my liver health?
Supporting liver health involves avoiding alcohol completely if you have Hepatitis B, maintaining a healthy weight, and eating a balanced diet rich in fruits, vegetables, and whole grains. Stay hydrated, avoid unnecessary medications or supplements that stress the liver, and don't share personal items like razors or toothbrushes. Regular exercise, adequate sleep, and stress management also help your liver function optimally.
What is Hepatitis B Surface Antigen and why does it matter?
Hepatitis B Surface Antigen (HBsAg) is a protein found on the surface of the Hepatitis B virus that appears in your blood when you're infected. It's the first marker to show up during infection, often appearing before symptoms develop, making it crucial for early detection. A positive result means the virus is present and you can potentially transmit it to others, which is why this test is so important for protecting your health and preventing spread to family members or partners.
What does a positive Hepatitis B Surface Antigen result mean?
A positive result means Hepatitis B virus is present in your blood and you have an active infection, either acute (recent) or chronic (long-term). This means you can transmit the virus to others and need medical evaluation to determine the infection stage and severity. Your doctor will likely order additional tests to assess liver function and recommend appropriate treatment or monitoring.
How often should I retest for Hepatitis B?
If your initial test is negative but you've had recent exposure, retest in 3-6 months since it can take time for the antigen to appear. If you have chronic Hepatitis B (positive result), your doctor will monitor you regularly, typically every 3-6 months, to check viral load and liver function. Healthcare workers and high-risk individuals with negative results may test annually or after potential exposures to ensure continued protection.
