回复: [翻译帖] 对六周窗口期的疑问和解释 -- For doubters of the 6-week window.
Original ContextHow long after a possible exposure should I wait to get tested for HIV?Most HIV tests are antibody tests that measure the antibodies your body makes against HIV. It can take some time for the immune system to produce enough antibodies for the antibody test to detect, and this time period can vary from person to person. This time period is commonly referred to as the “window period.” Most people will develop detectable antibodies within 2 to 8 weeks (the average is 25 days). Even so, there is a chance that some individuals will take longer to develop detectable antibodies. Therefore, if the initial negative HIV test was conducted within the first 3 months after possible exposure, repeat testing should be considered >3 months after the exposure occurred to account for the possibility of a false-negative result. Ninety-seven percent of persons will develop antibodies in the first 3 months following the time of their infection. In very rare cases, it can take up to 6 months to develop antibodies to HIV.
中文翻译:
我应该在怀疑感染多久后检测HIV?
大部分HIV检测是针对抗体的产生数量来对抗HIV病毒. 免疫系统会花点时间来产生足够的抗体来检测, 每个人都可能会不同. 这个时候就叫窗口期. 绝大部分人能在2~8周(平均25天)检测出来. 即使那样, 某些人的抗体仍然有机会花久点的时间来产生. 因此, HIV阴性结果应该要在大于3月来作准. 97%的人能在3月内产生抗体, 有很罕见的例子是超过6个月. |
