Brief Answer:
Does not seem to be HIV infected.

Detailed Answer:
Hi
A warm welcome to Healthcare magic.
Don't worry. Most probably you do not have HIV. Your report says you are negative for HIV. A second is advised after 6-8 weeks post infection, however the chances of change to a positive result is unlikely in case the first test done is a combo ELISA (you have done a combo ELISA).The exact accuracy is difficult to asess, but it is more than 99 %.

Hope I have answered your querry. Ask me if you have any more querry. Have a nice day.

Brief Answer:
Depend on level of exposure

Detailed Answer:
Hi
Welcoome back
There is no such data to predict how quick it can detect. it depends on the quantity of viral particle to which one is exposed. It again depends on load of virus present in the partner and the type of exposure, whether risky or less risky.

I hope it is clear now. Thanks once again. All the very best.
