Elisa Reactive & WB Indeterminate after 8 months?
Dec 18, 2012
Hi Dr. Wohl,
I had a possible exposure from being the receptive person during sex. I had an HIV test 6 weeks after this with a negative result. I recently had another HIV test, now 8 months after the possible exposure, where the Elisa was reactive but the WB test was indeterminate with the gp120/160 and 65 bands present. The other bands were all equivocal except for two of them.
So, I am wondering what the likely-hood is that I am HIV positive? Why would so many bands only be equivocal after 8 months if I am positive? Also, is it possible to develop anti-bodies from an exposure but not be infected?
Response from Dr. Wohl
This is unusual and I would be concerned about this result. I assume there has be NO possible more recent exposure.
These results need to be reviewed by an expert in HIV. A test looking for the HIV virus itself, like an HIV RNA PCR or a p24 antigen, would be recommended to check.
