Hello Dr.  

I post a question on Sept. 20 for risk assessment regarding a unprotected oral and protected vaginal sex I had with a sex worker.  

Now I the situation is getting complex:

Since my wife is pregnant, I took her for a HIV test just to be on the safe side.  All we have after my sex incident are KISSING and no oral or vaginal intercourse at all.

I got my 43 days MEIA test result NEGATIVE.

The scary thing was her test came back INCONCLUSIVE.  So please help me understand what's going on here.  

Test                               Result
HIV 1/2 Screen MEIA                Reactive
HIV 1/2 Supplemnetal EIA           Non Reactive
HIV 1 Western Blot                 Non Reactive
HIV 1 P24 Antigen Screen           Non Reactive

Her Dr. said she will not worry about this result as false negative happens on pregnant women.  BTW, my wife is Hepatities B virus carrier.  But we have not heard anything like this for the HIV routine test 7 months ago when she first found pregnant.

I was scared and then drive to another city and took the sex worker had sex with me to a clinic for a HIV test.  The rapid test came out NEGATIVE.  It was almost 9 weeks after the exposure.

So I guess the question I have are:

1.  Have you seen false positive like this before?  

2.  Is it true that pregnancy could cause false positive MEIA test?

3.  It seems the western blot is only for HIV 1 but not for
HIV 2.  Is it possible she got a HIV-2 which is not detectable by the WB?

4.  Do you think we should worry about this result?  

Thanks and best regards.
