90%: There's a period of time after a person is infected during which they won't test positive. This is called the “hiv window period.” The window period can be from 9 days to 3-6 months, depending on the person's body and on the HIV-test that's used. ...Read more

Yes, but...: If a person converts from HepBsAg negative to HepBsAg positive, her primary care doctor can evaluate her and order a larger panel of Hepatitis B tests to see what is going on. If HepBsAg is confirmed to be positive, the patient is contagious with HepB viruses (which are spread through blood and bodily fluids contact). That means all household contacts should have their HepB immunity confirmed. ...Read more

Acute hepatitis A: These data are difficult to follow, but i think these labs mean the following: you have chronic hepatitis b (hbsag+) and got acute hepatitis a on top of that. Your liver enzymes are now returning to normal. If this is true, you will not get hepatitis a again, but need evaluation for hepatitis b. ...Read more

How accurate is 12 weeks negative  stds blood test after exposure with unknown status men? HIV Elisa, rpr, hbsag, hcv, herpes.. Can I stop worrying

No more exposures?: If a woman is a worrier, she will worry until she stops exposing herself. So, at this time she can stop worrying and stop exposing herself. If she decides to expose herself again, she will worry again. It's a choice to expose or not to expose; thus, the worrying is her own consequence within her control. ...Read more

Statistical numbers: You should be concerned with the HbsAg positive titer, which MEANS that you have an acute Hep B infection, and not the numbers quoted. Those are statistical laboratory values used for quality control and tracking purposes, and for comparison with other positive results in the population, in order to keep the results accurate. Please discuss with your healthcare provider about what you need to do ...Read more

ALT/AST little increase ,HbsAg screening +ive and by ELISA its value is16.53.HBVDNA BY PCR is -ive. Now can I be vaccinated ??

False + tests ?: if your HbsAg is positive, that means you are either actively infected with Hep B, or are a chronic carrier. The HBVDNA test should be positive if you are antigen +, so I think you need to retest and discuss this with your GI doctor s to why the tests don't agree. I think you need to wait before you vaccinate with these test results, this sounds like you have active Hep B infection until disproven ...Read more
