HI, I had sex with an escort and I have undergone tridot test and westren blot test at 3,5,6 month's post exposure and the result was declared negative it's been 1.5 year's since I had the encounter but from last 2 month's I have lost 12 kg's of my body weight and from past few day's I am feeling drowsy,and I am feeling as if their is no energy in my body. I am really scared I want to know whether tridot test is a reliable one or do I need to retest again.
