Can ELISA test for HIV be trusted?

How far can the ELISA test for HIV be trusted? I got my blood test (ELISA) done after six months and nine months of exposure and both the time it was negative. Can I trust these tests and feel that I am not infected by HIV? Do I need any further test for HIV and if so, when?

 

You can be thankful that you have not got the infection inspite of exposure. You do not need further testing if the two tests were done at a good reliable lab. Please take care and avoid exposure. If you must have casual sex, please use a condom from start to finish.
