HIV TESTING: When thinking of tested for HIV, there are a few important things to consider:
There are a couple of different types of tests being used to help people determine if they have been infected with HIV. However, when people say "HIV test", they are usually referring to a standard antibody test.
有几种HIV的检测方法，一般是指标准的抗体检测。
（注：美国的标准HIV抗体测试是指酶联四代）
When having a standard HIV antibody test, there must be at least six weeks time between the time a person was last at risk for contracting HIV and the time that he/she gets a test done. Some people call this the "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 six weeks for the body to produce enough antibodies for a standard HIV antibody test to be accurate.
在高危后6周进行标准的HIV抗体测试。也有人叫这段时间为“窗口期”。HIV抗体测试是测人体因HIV病毒而产生的HIV抗体。对绝大多数人来说，6周而产生的抗体对HIV抗体测试来说是足够多的了，其结果是真实可信的。
If people are continually at risk (active intravenous drug users, for example), they may want to get tested even if six weeks have not passed since their last risk. If the test result is negative, though, people may want to get retested again later.
对反复高危者（如静脉注射毒品）应该在每次高危后6周测HIV抗体。
