Hi,
Thanks for posting the query on XXXXXXX
I would like to comment the following regarding your query:
1. After the episode of exposure, immediately a baseline ELISA test for HIV antibodies is recommended to exclude an already existing HIV infection.
2.A follow-up ELISA for antibodies against HIV should be performed at 4 to 6 weeks, 3 months, and 6 months after exposure.
3. Depending on the type of exposure, post exposure prophylaxis may be taken under medical supervision.
I hope I have answered your query. Please accept my answer if you have no follow up queries. I will be glad to answer any follow up queries.
Wish you good health.
Take care.

sir, is the negative result at eaxctly 6 months after exposure not sufficient to rule out an hiv infection ..
is it possible to become positive after 6 months of exposure if I had no earlier or afterwards exposure than the one I have mentioned ?

Hi XXXXXXX,
Thanks for the follow up.
The period of negative result in spite of hiv infection due to non detection of antibodies is called the window period.The vast majority of people (97%) have detectable antibodies by three months after HIV infection; a six-month window is extremely rare.
Thus it is extremely rare to become positive after 6 months from the history of exposure.
