Blood donation when unknowingly exposed to Hep B
September 22, 2012 12:23 AM Subscribe
I just found out a close family member has had Hepatitis B for years. I last met them a month ago; my vaccinations are up to date. Does this mean I can't donate blood for another nine months of not-seeing this family member?
To complicate things, I have been a blood donor for two years. I never knew about the Hep B, and I suppose I should've asked. Does this mean I may have unknowingly infected someone or something? I'm a bit flustered, not least because I was looking forward to donating again this weekend till I found out. Thank you.

Hep B is something you may or not be vaccinated against, which you can check on, but it's transmitted by sexual contact or IV drug use (or other blood/body fluid contact.). So unless your definition of close family member is significantly different than the norm, no, you're fine. Normal kissing, sweat, tears, unless bloody (eg dental work saliva is not 'normal' since it's often bloody) is not considered a source of transmission.

or sharing razors, I've heard. Casual contact is not sufficient.

I used to get Blood Borne Pathogens training once a year because it was conceivable that I might interact with human derived materials. They really drilled the fact that the issue with Hep B and Hep C was how long they'd remain infectious relative to HIV. Assuming you didn't share a razor or a toothbrush (I'm not sure that there are any known transmission events from these two sources, but I've heard them cited) and no blood was otherwise shed, you should be fine.

If you get vaccinated, make sure to tell them at the donation center. Thanks for being a blood donor; it is genuinely a life-saving gift.

Call the blood bank and ask to speak with a supervisor, that's the best way to find out definitively. All blood banks have to operate under FDA guidelines but each has their own stricter set of rules in place so there is a little bit of variation. Get the answer directly from the horse's mouth.

You can also feel OK about the blood that you donated in the past - blood is tested for Hepatitis B. So really, between the odds of you not getting it and the odds of it not being caught in the donor blood testing, your donations were safe.
If there's still any question in your mind, feel free to say something to the person interviewing you for donation when you go in to donate next. They're trained to know when it is or isn't okay, and will appreciate your honesty.
And I would also like to say thank you for donating blood. I work in a blood bank and have seen donated blood be the reason someone is alive today. So, thanks!

Response by poster: So I just got back from my appointment less 450ml of blood. :D I checked, and they said it should be okay, and went on to explain the tests and all that they do on the blood. Also, I've learned that 'close proximity' does not mean what I thought it did. Thank you for all your answers.
Thank you also for the kind words! Knowing of course that many other people donate, yippee to them too! I also always vaguely thought that 'you're saving lives!' was some kind of platitude, but this thread kind of changed my mind. Thank you all.
