What's this test for?

This test is ideal if you've been exposed to Hepatitis B, work in healthcare, or need to verify your immunity status. It helps detect past Hepatitis B infections that may have resolved on their own or determine if you've been infected before, even if you never had symptoms. Many people use this test to confirm their liver health status or as part of routine infectious disease screening.

How should I prepare for this test?

No biotin: 72 hours

If you're taking high-dose biotin supplements (also called vitamin B7, B8, vitamin H, or coenzyme R), you should stop taking them at least 72 hours before your blood draw. Biotin can interfere with some of the test components and affect result accuracy. Other than this supplement restriction, no special preparation like fasting is required for this test.

What's included in this test?

Hepatitis B Core Ab Total

This test measures Hepatitis B Core Antibody Total, which indicates whether you've ever been exposed to the Hepatitis B virus. This antibody can appear during active infection or persist for years after recovery, helping identify both current and past infections. It's particularly valuable because it may be the only remaining marker of Hepatitis B infection when other antibodies have disappeared, providing crucial information about your liver health history and immune status.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your Hepatitis B Core Antibody status means for your liver health and immunity. These notes include personalized recommendations like whether you need vaccination, further testing, or lifestyle changes to protect your liver. You'll also get the standard lab report and can track your results over time using our trends feature, which is especially helpful if you're monitoring chronic infection or verifying immunity.
Who should consider getting this test?
This test is important for healthcare workers, people with known exposure to Hepatitis B, those with elevated liver enzymes, and anyone wanting to verify immunity status. It's also recommended if you were born in areas with high Hepatitis B rates, have household members with Hepatitis B, use injection drugs, or are on dialysis. Additionally, pregnant women and people planning to start immunosuppressive therapy often need this screening.
What symptoms indicate I may need this test?
You may need this test if you're experiencing unexplained fatigue, jaundice (yellowing of skin or eyes), dark urine, or persistent abdominal pain. Other signs include loss of appetite, nausea, joint pain, or unexplained weakness. However, many people with past Hepatitis B infections never had symptoms, which is why screening based on risk factors rather than symptoms alone is often recommended.
What does a positive Hepatitis B Core Antibody result mean?
A positive result means you've been exposed to Hepatitis B virus at some point, either recently or in the past. This could indicate a current infection, past infection that has resolved, or immunity after natural infection. Additional tests are typically needed to determine whether the infection is active or resolved, and whether you're immune or need vaccination.
How can I protect my liver health naturally?
Support your liver by limiting alcohol consumption and avoiding unnecessary medications or supplements that stress the liver. Eat a balanced diet rich in fruits, vegetables, whole grains, and lean proteins while staying well-hydrated. Maintain a healthy weight through regular exercise, avoid exposure to toxins and chemicals when possible, and practice safe behaviors to prevent viral hepatitis transmission.
What is Hepatitis B and why does it matter?
Hepatitis B is a viral infection that attacks the liver and can cause both acute and chronic disease. It spreads through contact with infected blood or body fluids, making it a concern for healthcare workers, people with multiple partners, and those sharing needles. While many adults clear the infection naturally, chronic Hepatitis B can lead to serious liver problems including cirrhosis and liver cancer, making early detection and monitoring crucial.
How often should I retest for Hepatitis B antibodies?
If you're at ongoing risk due to occupation or lifestyle, annual testing is often recommended. If you're monitoring chronic infection or treatment, your doctor may suggest testing every 3-6 months. For those who tested negative but received vaccination, a single test 1-2 months after completing the vaccine series confirms immunity, with retesting generally unnecessary unless immune status becomes questionable.
