Negative HIV Combi Immunoassay Test, Negative Rapid Test. Should I Go For Western Blot Test?

Posted on Sun, 26 Aug 2012

Question: Hello i had a hiv combi immunoessay test after 3 months and 14 days it was negative
and had a rapid test of 15 mins after 6 and 28 days both were negative
do you think i must go for any other test say western blot

Hello and thanks for the query.
HIV combo test is a fourth generation test and is highly sensitive test to detect p24 antigen and HIV antibody test.
Since you have been tested negative at 3 and a half months,after the exposure,this sufficiently rules out any HIV infection,since by 3 months the antibodies are sufficiently formed.

I hope to have answered your query however you may revert to me for any other query.
Best of luck
Thanks
