When thinking of getting tested for HIV, there are a few important things to consider:

• Window Period: The HIV test is looking for antibodies, which are the body’s response to having HIV in it. For most people, it takes 6 weeks for the body to produce enough antibodies for a standard HIV antibody test to be accurate. Some people call this the "window period". The Massachusetts Department of Public Health recommends waiting 6 weeks between an individual's possible HIV exposure and the time they get tested, providing there are no risks within that time period. For a conclusive test result, it’s recommended to wait 3 months before getting tested.
  

当想检验HIV的时候，需要考虑如下重点：
1，窗口期：HIV检测是找抗体，抗体的产生是人体对病毒侵入的反应。对于绝大多数人来说，六周时间能够产生足量抗体用于准确的标准的HIV检测。一些人称之为窗口期，麻省公共健康部推荐在可能HIV暴露六周后去检测，而且这六周中没有复高。三月检测是决定性的结果。


Why do some sources advise waiting longer than 6 weeks for HIV testing?
Most people will test accurately for HIV after 6 weeks have passed since their last risk. In some cases where a person has a highly compromised immune system, such as those in which a person has recently undergone chemotherapy or an organ transplant, it may take 3-6 months for their body to develop enough antibodies to test positive.

These are very extreme situations, however, and other more common conditions such as colds or the flu, diabetes, asthma, and many others, will not affect the body's development of HIV antibodies in that way. Those who suggest window periods longer than 6 weeks are trying to account for all those who may also have compromised immune systems. The CDC (Centers for Disease Control and Prevention) recommends waiting 3 months for a conclusive test result.


为什么一些机构建议六周更长的时间检测呢？

大多数人六周的检测是足够准确的，一些情况下，譬如：患有严重免疫力低下系统疾病的人，例如：一个人刚刚进行化疗，器官移植，需要3到6月产生足够检测到的抗体。

然而，其他极端情况和一些普通疾病 例如 风寒，感冒，哮喘啥的，不会影响人体抗体的产生。这些建议长于六周检测的机构是为了考虑到那么有免疫系统疾病的人。bla bla bla。。。
