Probably, clarify.: The standard HIV test is first the elisa, for screening, and then the western blot for specificity. The western blot is done if the elisa test is positive. Nucleic acid tests, like pcr, are used in testing donor blood. Although the basic tests can be extermely accurate there is a chance of false negatives due to the up to 6 month seroconversion time it takes to make antibodies. See my comment.

That is good, but still it might be good for you to get a screening test 6 months after contact with her to be sure for the reason(s) in my answer. Best of luck.

I expect you to be negative since iinfected and false negative people usually take 30 days to seroconvert, and all those results were neg. But if you had that encounter, then the tests, and have been negative for 4 months, there might still be a chance since it can take 6 months. It would be wise to see the doctor, tell him/her of this, and contact that female if you can so she can get tested.

Protocol: The general protocol would be a 4th generation eliza at 1 ,3 and 6 months or a DNA nucleic acid test at 6 months. Hope this helps

Agree with Dr. J.: It is good that the test results are negative. To be sure, get a HIV nucleic test at 6 months after exposure. Have a healthy diet, exercise, drink plenty of water, have safe sex, and get HPV vaccine. Wish you good health! Nutrition: http://www.choosemyplate.gov/.
