Anti HCV ab - result non - reactive hbs ag( chemiluminescence) - result - negative 

please advise on my results. Thanks very much ?

No infection: These results are most consistent with never being exposed to hepatitis c, and not having chronic infection with hepatitis b. It can take several months for hcv antibody to be detected, so if you had a recent high risk exposure this should be repeated at six months. If hepatitis b surface antibody is not present, then consider hbv vaccination for future protection ( there is no vaccine for hcv). ...Read more

Took HIV Antibody 1&2 Test and P24 Antigen test 10 days after PEP. Results non-reactive. A bit early. All other blood panel metrics normal. Thoughts?

Took HIV Antibody 1&2 Test and P24 Antigen test 10 days after PEP. Results non-reactive. A bit early. All other blood panel metrics normal. Thoughts?

Not conclusive: These results are reassuring; it is unlikely you were infected. However, the results are not conclusive. Following PEP, it is necessary to test for HIV longer than otherwise, maybe up to 4 months. (PEP is great when needed, but it prolongs the time of uncertainty about whether infection occurred.) Discuss with the clinic or doctor who prescribed the PEP and follow his or her advice. ...Read more

I took a 5th gen Ag/Ab HIV test 39 days post possible exposure. Result was non-reactive. Am I ok?

Conclusive HIV test: "Fifth generation" for an HIV test is marketing hype -- the manufacturer calls their new test 5th gen, but it's still bacially the same as all other 4th generation tests. Results of 4th gen HIV tests are usually conclusive after 4 weeks and always by 6 weeks (42 days). But 39 days is close enough; for sure you didn't catch HIV. ...Read more

If you are hepatitis b reactive, and then you are test again for HBsAG and the result is non reactive what does it mean? You don't have hbv?

If you are hepatitis b reactive, and then you are test again for HBsAG and the result is non reactive what does it mean? You don't have hbv?

Reactive to what?: Hbv markers are used to distinguish actively infected from immunity, the latter include antibody to surface antigen (hbsab) and to the core antigen (hbcab). Some tests detect part of the virus, such as surface antigen (hbsag), the core antigen, or hbv dna. The presence of hbsag indicates that the person is potentially infectious. Hbsab replaces hbsag as the hbv infection evolves to immunity. ...Read more
