Hi All,

I had a unprotected sex with prostitute before 100 days. blow are my test results,

HIV 1 RNA Quantitative test on 33 days - Negative
CMIA - 7 weeks - Negative
ELISA - 9 weeks - Negative
CMIA - 11 weeks - Negative
HIV 1 RNA Qualitative using cobas Taqman method - NOT DETECTABLE (81st day)
HIV 2 - RT PCR - Not detected (81st day)
both CMIA / ELISA on 90th day - Negative.

Done STD tests on 88th day - All Negative.

I am having all the symptoms like lymph nodes, rashes from 20 days onwards. i had in persistent fever for 3 weeks from 6th week onwards. i lost weight about 5 kg and gained 2.5 kgs back.

My doctor tole me that 97% people will be positive by 3 month. so he wants me to do a ELISA on 6th month. is there any way that ELISA can be positive in 6th month. so you think i need to do test again.

Hi Sekar and thanks for reaching out to the AIDS Vancouver Helpline. My name is Colin and I am happy to answer your questions.

I understand you are concerned about the possibility of a positive HIV test taking up to 6 months to appear on your HIV test. I hope the information I can give you will help put your mind at ease.

In terms of testing, it looks like you've had an assortment of tests all taken during appropriate window periods and they have all come back negative--that's great! Any commonly-administered HIV test is considered conclusive at or after 12 weeks post-exposure (84 days; 3 months). Given the timeline that you've mentioned, it seems like you've had 2 tests that would be considered conclusive and a few others taken when their accuracy would be high >90% all indicating your negative status. Again, this is great!

With regards to the potential for your results to take longer to show up on a test if you were HIV positive, there are only four factors that are known to effect the accuracy of HIV test results: if you are currently undergoing chemotherapy treatment for cancer, if you are on antiretroviral treatment for Hepatitis C, if you are currently undergoing a course of Post-Exposure Prophylaxis (PEP) for a known HIV exposure, or if you have a congenital immunodeficiency. If you do not fit into one of these categories--and it seems like you don't--then there is no reason that your tests wouldn't follow a similar timeline. If you would like to test again in 3 months to be absolutely sure, you are of course welcome to, but in our opinion it is not strictly necessary for this exposure.

One final thing I must mention is about symptoms. While it is true that many people experience flu-like symptoms during their [seroconversion](, these symptoms are not specific to HIV and are not used in the diagnosis of HIV. These symptoms are common to many viral infections including the common cold and the flu and therefore the only way to be sure of your status is to take an appropriate test at the right time.

I hope the information I've been able to provide to you has been useful. Please feel free to post again if you'd like any more information or clarification.

All the best
