Testing combo to rule out HIV

Jul 26, 2002

Dear Dr. Kull,

1. Does the following testing combo completly rule out HIV infection at 8 months post exposure 2. If so why? 3. Have you heard of anyone who has had these tests all negative at such a late stage and still be infected?

Negative PCR DNA, ELISA, Western Blot and P24 Antigen

Kind Regards,


Response from Mr. Kull

One HIV antibody test performed three or more months after exposure is sufficient. There is no need for multiple tests unless there was a known high risk exposure and symptoms you are experiencing are indicative of HIV infection (as determined by a doctor).

Antibody screening is highly, highly sensitive, and intial results are always confirmed by repeat testing on the same sample to rule out error.
