Elisa on the 84th day? Is it conclusive?

Question: 

Hi!

On 10-11 September night (2016) I kissed and give a guy a handjob! He did not ejaculate, but there was a lot of precum. I do not remember if I had any cuts/abrasions on my hand. Also, he touched my panties where the vagina was with his finger and I do not remember If he had touched his penis before.

On December 2, 2016 - he TOLD me he took a combo CMIA Hiv test that was negative.
On December 3, 2016 - I took an ELISA - I think it was 3rd generation, but I am not sure. Might have been 4th.

So, I took my test exactly on the 84 day (arter 83.5 days to be exact) and it was negative.

IT IS CONCLUSIVE ? Or should I retest? Thank you!

Answer: 

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about the conclusiveness of an ELISA 3rd Generation test. From the information given, this scenario is determined to be Negligible Risk (There are no evidence or no documented cases of transmission). This risk level presents a potential for HIV transmission because they do involve the exchange of body fluids. However, there has never been a confirmed report. For a risk to exist, specific HIV positive fluids must come into direct contact with the blood stream of an HIV negative person.

In regards to the conclusiveness of the ELISA test, consider the following. The Elisa test is a blood test that looks for antibodies. This test has a window period of 4 weeks to 3 months (although up to 95% of infections are detectable within 4-6 weeks). Most people develop detectable antibodies in 21-25 days. The accuracy of this test is 99.9% [1]. At 84 days, the results would be considered conclusive.

Recommendation: There are no evidence or no documented cases of transmission refer to a Physician for more personalized answers
