I have just learned I have high anti-HBs from a blood test - 54.8 IU/L. I was vaccinated about 18 years ago (3 injections over 6 month course). It's flagged as abnormal on my test results, is this a concern? Does a high level mean I might have lost immunity and then been infected With hepatitis B (no idea how, I have had two C sections since vaccination but no transfusions and no other risk factors).
I really appreciate you taking the time to read this.
Thank you SO much. I'm not sure why my anti-HBs result was flagged as abnormal but I guess the lab doesn't know who has been vaccinated and who hasn't. My husband's result was ten times smaller than mine, but I guess everyone's different. I really appreciate your response, thank you mikesimon!
I agree with you. If you hadn't been previously infected or vaccinated then you wouldn't have shown any antibodies to hep b so your test result was out of reference range.
I don't know much about hep b but if your husband's antibodies are a lot lower than yours you might want to ask his doctor if he is still immunized against hep b. I certainly don't want to alarm you and, as I stated, I don't know much about this disease but, it's always better to be safe than sorry. Really, I doubt there is anything to worry about but I always play it safe.
Anti Hbs levels above 10 IU/L are considered to be protective. So, you don't have to worry about the high levels, it just shows more antibodies to fight the infection. People with three doses usually exhibit more titers then those with two doses.
