“延迟的血清转化”。我们都听说过很恐惧的故事,比如不知道为什么感染之后几年,甚至几十年一直检测为阴性而检查不出来。这就是一堆“你知道吗?(译注:直译,应该就是以谣传讹的人的开头语)”。根本就没那么回事,仅仅是一个乡间传说。假如一个人感染了HIV病毒,实际来说很快就可以查出来(通常是高危后6周以内)。(译注:美国的版主一样支持6周论)3个月将是终极的结果。假如3个月之后的检查是阴性的话那么这个人没有感染HIV。唯一的例外就是那些免疫系统几乎完全丧失的人可能需要更长的时间产生抗体。这些人包括极小一部分先天免疫缺陷的,和后天免疫缺陷的,比如接受器官移植的采纳了免疫抑制药物的,正在接受化疗的,癌症晚期的,还有,没有免疫能力的人。即使这些人血清转化的“延迟”在医学专业领域也饱受争议。即使这些人通常也在符合3个月窗口期之说,但是为了保险起见,还是建议那些有免疫缺陷的人查到6个月。再没有其他人需要查到3个月以后。假如服用了阻断药物(PEP),那要在服用最后一剂PEP的3个月之后检测。

“自身免疫功能紊乱”。这经常和我上面所说的免疫缺陷混淆。自身免疫性疾病(比如风湿性关节炎)和由于化疗等原因造成的严重的免疫系统缺陷完全不同。自身免疫功能紊乱不影响检测时间的指南,也不影响检测结果
