Hello, I took the Duo test (Elisa + P24), after 38 days and the result was negative, I felt so relieved when I saw an answer saying that if it was negative, then everything's ok, but then it mentioned a case of a person who took profilaxis and it did not work. I took the 30 day treatment and I would like to know if The result is not trusworthy because of the treatment I took, please somebody answer
