Detailed Answer:
Hi
Thank you for query. I am Dr Bharatesh D Basti answering your query.
It is good that HIV DNA PCR, antigen and antibodies tests have come negative. The DNA PCR test, duo test are highly sensitive after 2 and 3 weeks exposure respectively. It is 95- 99% sensitive. So you are unlikely to have HIV. There is no need for any test for now
It is better to go for final conclusive test after 3 months.
You can get back for any clarification.
