Brief Answer:
You are free from HIV.

Detailed Answer:
Dear XXXXXXX

Welcome to HCM.

You had unprotected sex with someone but the test result for HIV after 18 months of exposure is negative then the result is considered as 100% conclusive and you are absolutely free from HIV because the window period for HIV infection also varies from 15 days to 3 months.

The value for RNA PCR is just for reference but it doesn't mean that you are carrying the virus so calm down, XXXXXXX the fear and forget aboput the episode. Be relaxed and move on in your life happily. For any further query feel free to ask and I am here to help you out.

Thank You

but sir i have read somewhere that normal range for viral load copies through RNA PCR should be less than 40 copies/ml or less than 75 copies/ml but in my report result came as less than 97 copies/ml but still they have mentioned in the end "TARGET NOT DETECTED".This is what concerns me that it did not came as less than 40 copies/ml.what could be the reason for this?

Brief Answer:
The value has not of much significance.

Detailed Answer:
Dear XXXXXXX

Welcome back and thanks for follow-up.

The reference value for RNA PCR is less than 40 copies but up to 100 copies the result is highly reliable so no need to get worried or tensed as the risk is not there in your case so be relaxed, forget the episode and move on in life happily.
