Hi there. Getting educated is a great idea! That certainly can help with anxiety about a subject. MedHelp adheres to the position of the CDC as well as the input of expert physicians that HIV is only transmitted through unprotected vaginal or anal sex, the sharing of needles, or from mother to child. A 28 day test is considered accurate and conclusive, so if negative then, it should remain negative. And any time someone tests after a non risk exposure, it, of course, will be a negative result. I hope this has eased your mind and wish you the best of health.
