Gambit sanırım şu kısım baya aydınlatıcı. Paylaşım için sağol "Cases of prolonged or no seroconversion have rarely been reported.24,25 These initial reports were all tested with older generation antibody tests and many of these long window period cases tested HIV RNA negative on retesting, suggesting infection was caused by a re‐exposure at a later date. It is therefore important to stress that the majority of the population will seroconvert within 3 months; however, repeated re‐exposure is common and that can seemingly prolong the seroconversion period. In cases where post‐exposure prophylaxis (PEP) was given it is still recommended that a 6 month follow up period should be allowed to exclude the majority of seroconversions21 simply because of the lack of literature to prove otherwise and because antiretrovirals may reduce replication and prolong antibody response (evidence level IV, recommendation grade C)."
