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 your antibody level means for your protection status. These notes include personalized recommendations like whether you need a booster vaccination, steps to take after potential exposure, or documentation for workplace requirements. Along with your standard lab report, you can track your immunity levels over time using our trends feature to monitor if and when booster shots might be needed.

When will I get my results?

Results are typically available within 1-2 business days after your blood sample is collected at the lab. You'll receive an email notification as soon as your results are ready to view securely online. If you need results urgently for work or after an exposure incident, check with the lab about expedited processing options.

Who should consider getting this test?

Healthcare workers, dentists, first responders, lab technicians, and anyone with regular exposure to blood or bodily fluids should consider this test. It's also important if you've been vaccinated but never confirmed immunity, if you're starting a job that requires proof of Hepatitis B protection, or if you've had a needlestick injury or potential exposure. People traveling to high-risk areas or those with family members who have Hepatitis B may also benefit from knowing their immunity status.

What does it mean if my antibody level is below 10 mIU/mL?

An antibody level below 10 mIU/mL means you may not have adequate immunity to Hepatitis B and could be at risk if exposed to the virus. This can happen if you were never vaccinated, if your vaccination didn't produce a strong immune response, or if your immunity has waned over time since vaccination. Your doctor will likely recommend getting a booster shot or completing the full vaccination series to build up protective antibodies.

How long does Hepatitis B immunity last after vaccination?

For most people who develop adequate antibodies after vaccination, immunity can last 20 years or longer, and possibly for life. However, antibody levels can decline over time, especially in people who were vaccinated as infants or who have certain medical conditions. This is why retesting is recommended for healthcare workers and others with ongoing exposure risk to ensure they maintain protective levels above 10 mIU/mL.

What should I do if I've been exposed to Hepatitis B?

If you've had a needlestick injury, sexual contact with someone who has Hepatitis B, or other potential exposure, get tested immediately to check your current immunity level. If your antibody level is protective (above 10 mIU/mL), you're likely safe. If it's low or you're not immune, your doctor may recommend Hepatitis B immune globulin (HBIG) for immediate protection and starting or completing the vaccination series. Time is critical, so seek medical attention within 24 hours of exposure.

How often should I retest my Hepatitis B immunity?

If you work in healthcare or have ongoing exposure risk, many employers require retesting every 1-2 years to ensure you maintain protective antibody levels. For people who were vaccinated but don't have regular exposure, retesting isn't usually necessary unless you have a specific exposure incident or need documentation for work, school, or travel. If your levels are low or borderline, your doctor may recommend more frequent monitoring after booster vaccination.
