What's this test for?

This test is ideal if you need to verify whether you're protected against Hepatitis B, whether from previous vaccination or past infection. It helps you determine if you need a booster shot, which is especially important for healthcare workers, people with chronic liver disease, or those at higher risk of exposure. Many people use this test to confirm their immunity status before traveling internationally or starting a new job in healthcare.

How should I prepare for this test?

No special preparation is needed for this test. You don't need to fast or avoid any medications. The test can be done at any time of day, and you can eat and drink normally before your appointment. Just arrive at the lab with your test order and photo ID.

What's included in this test?

Hepatitis B Surface Antibody Ql

This test measures Hepatitis B Surface Antibody, which indicates whether your immune system has developed protection against the Hepatitis B virus. The presence of this antibody shows that you've either been successfully vaccinated or have recovered from a past infection and are now immune. This single biomarker provides a clear answer about your current immunity status.

What happens after I get my results?
You'll receive doctor notes in simple language explaining whether you have immunity to Hepatitis B and what that means for your health. These notes include personalized recommendations like whether you need a booster vaccination, how to maintain your protection, or if further testing is needed. You'll also get the standard lab report and can track your immunity status over time using our trends feature if you need periodic monitoring.
When will I get my results?
Most results are available within 1-3 business days after your blood sample is collected at the lab. You'll receive an email notification when your results are ready to view in your secure online account. Complex cases may occasionally take a bit longer, but the majority of tests are processed quickly.
Who should consider getting this test?
This test is essential for healthcare workers, first responders, and anyone in occupations with potential blood exposure. It's also important for people with chronic liver disease, dialysis patients, pregnant women, international travelers to high-risk areas, and anyone who wants to confirm their vaccination protection. If you were vaccinated as a child and aren't sure if you're still protected, this test provides clarity.
What does a positive result mean?
A positive result means you have protective antibodies against Hepatitis B, which is good news. This indicates you're immune to the virus, either from successful vaccination or recovery from a past infection. You're protected and don't need to worry about getting Hepatitis B, though depending on your antibody level, your doctor may recommend a booster in the future.
What does a negative result mean?
A negative result means no protective antibodies were detected, which indicates you're not currently immune to Hepatitis B. This could mean you were never vaccinated, your vaccination didn't produce adequate immunity, or your immunity has waned over time. Your doctor will likely recommend getting vaccinated or receiving a booster shot if you were previously vaccinated.
What is Hepatitis B and why does immunity 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, and chronic Hepatitis B can lead to serious complications like cirrhosis and liver cancer. Having immunity through vaccination or past infection protects you from getting infected, which is why confirming your immunity status is important for your long-term health.
How often should I retest my Hepatitis B immunity?
For most people with confirmed immunity, routine retesting isn't necessary as immunity typically lasts for life. However, healthcare workers and those at ongoing high risk may need to retest every 5-10 years to ensure adequate protection. If you're starting immunosuppressive therapy or chemotherapy, your doctor may recommend retesting since these treatments can affect immunity.
