文章名字：什么是窗口期
原文
The window period is the period between the onset of HIV infection and the appearance of detectable antibodies to the virus. In the case of the most sensitive HIV antibody tests currently recommended, the window period is about three to four weeks. This period can, however, be longer.Any antibody-based blood tests (such as the ELISA, rapid tests and the Western Blot) conducted during this window period may give false negative results.Antibodies are produced from about three weeks after infection and usually become detectable by four to six weeks after infection. This four- to six-week period between infection and a positive test is called the window period.This means that although the virus is present in the person's blood there are, as yet, no (detectable) antibodies in the blood. In such cases the tests erroneously show that the person has not been infected. During this window period the individual is already infectious and may unknowingly infect other people. People who are exposed to or who practise high-risk behaviour are well advised to arrange for a repeat test after three to six months - and to use safer sex practices like condoms while waiting for their results.In some people, the window period may be longer; although unusual, it may take up to three months for an antibody test to become positive after they have been infected. People who think that they might have been exposed to infection are therefore usually asked to wait at least four weeks before having the HIV test. Also, even if the first test is negative (i.e. no antibodies detected), a follow-up test should be done three months after the suspected exposure.
只说重点
对于最敏感的艾滋病毒抗体测试目前推荐,窗口期是大约三到四个星期。这段时间可能更长。
任何基于血液测试(如ELISA、快速测试和免疫印迹)期间进行这个窗口期可能给假阴性结果。
产生抗体从大约三周后感染,通常成为到4 - 6周后感染。这4到6周期间感染和阳性测试被称为窗口期。
在这个窗口期个人已经可能不知不觉地传染给其他的人。那些暴露在高危行为或者测试阳性的，建议三到六个月后在测,在此期间使用更安全的性行为像避孕套，然后在等待他们的结果。
在一些人,窗口期可能会更长,尽管不寻常,它可能需要三个月为一个抗体测试成为阳性。
这说明，6周是很可靠的。
能上这个坛子看帖子的人，都是健康人的。不会3月测不出。
好贴顶一个
