What's this test for?

This test is ideal if you've received a Hepatitis B Immune Globulin (HBIG) shot and need to confirm it's providing protection. It's commonly used for transplant recipients, healthcare workers exposed to Hepatitis B, or infants born to mothers with Hepatitis B who need to verify their immunity levels. The test measures whether your body has adequate antibody protection against the Hepatitis B virus after vaccination or HBIG treatment.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining your Hepatitis B antibody levels and what they mean for your immunity status. These notes include personalized guidance on whether you need additional HBIG doses, booster vaccinations, or continued monitoring based on your specific situation. Along with your standard lab report, you can track your antibody levels over time using our trends feature to ensure ongoing protection, especially important for transplant patients or those with chronic exposures.

What's included in this test?

This test measures Hepatitis B surface antibody (anti-HBs) levels. This measurement is critical after HBIG administration to confirm the treatment is providing adequate protection, and it helps doctors determine if additional doses are needed or if your body has developed its own immunity from vaccination or previous infection.

Who should consider getting this test?

This test is essential for liver transplant recipients who need lifelong Hepatitis B protection, healthcare workers who've had needlestick injuries involving Hepatitis B, and infants born to mothers with Hepatitis B infection. It's also important for anyone receiving regular HBIG infusions who needs to monitor whether their antibody levels remain protective, or people who want to verify their immunity after completing the Hepatitis B vaccine series.

What do Hepatitis B surface antibodies mean?

Hepatitis B surface antibodies (anti-HBs) are proteins your immune system creates to fight off the Hepatitis B virus. When you have adequate levels of these antibodies, you're protected against Hepatitis B infection. They can develop naturally after vaccination, recovery from infection, or from HBIG treatment, which provides immediate but temporary antibodies while your body builds its own long-term immunity.

What level of antibodies means I'm protected?

Generally, an antibody level of 10 mIU/mL or higher indicates protection against Hepatitis B infection. For transplant recipients or immunocompromised individuals, doctors often want to see higher levels (100-150 mIU/mL or more) to ensure adequate protection. Your healthcare provider will interpret your specific results based on your medical situation and risk factors.

How can I maintain my Hepatitis B immunity?

If you've been vaccinated, maintaining a healthy immune system through balanced nutrition, adequate sleep, and stress management helps preserve your antibody response. For transplant recipients or those on immunosuppressive medications, following your doctor's HBIG infusion schedule precisely is essential. Regular monitoring ensures your antibody levels stay protective, and booster vaccines may be recommended if levels drop below the protective threshold.

What does it mean if my antibody level is low?

Low antibody levels mean you may not have adequate protection against Hepatitis B infection. This could happen if you haven't been vaccinated, didn't respond well to the vaccine series, or if your antibodies have declined over time. For those receiving HBIG, low levels might indicate it's time for another dose or that the treatment interval needs adjustment to maintain protective immunity.

How often should I get tested after HBIG treatment?

Testing frequency depends on your specific situation. Transplant recipients typically test monthly for the first several months, then every 3-6 months long-term. Healthcare workers exposed to Hepatitis B usually test at baseline, 6 weeks, 3 months, and 6 months after exposure. Your doctor will create a monitoring schedule based on your antibody levels, HBIG dosing, and risk factors.

What should I do if my antibody levels are declining?

Declining antibody levels indicate you may need a booster vaccination or adjusted HBIG dosing schedule. Contact your healthcare provider to discuss whether you need additional protection, especially if you're at continued risk of exposure. For transplant recipients, your transplant team will typically schedule an additional HBIG dose or adjust your treatment regimen to bring your antibody levels back into the protective range.
