Is a non reactive test for AIDS conclusive?
Q: If the HIV tests were done at 8 weeks, 12 weeks and 16 weeks post exposure, would a non reactive result be conclusive?
A:If a reliable test is carried out at 16 weeks post-exposure and the result is non reactive or negative for HIV antibodies, it is almost certain that HIV infection has not occurred. Even though the infection has not occurred this time, it does not mean the person will be similarly lucky next time! Please avoid all casual sex and if you cannot, then use a condom from start to finish. Remember that a condom is not 100% safe as accidents do happen so abstinence or totally avoiding casual sex is the only absolutely safe procedure.
