How long is the window period? There is currently a lot of debate in the medical community about how long the window period is. Some say 6-8 weeks, while others say 3 months. The most conservative one is 6 months! The more commonly accepted view in China is 3 months.

How to calculate the window period? The calculation of the window period should be calculated from the time of high-risk behavior or the time of receiving a blood transfusion. That is to say, if you have high-risk sexual behavior or receive a blood transfusion on January 1, then the time for you to receive the antibody test should be from 1 Six weeks from the 1st of the month, that is February 12th.

Will different infection routes affect the length of the window period? There are no specific symptoms of pre-AIDS or infection. The antibody test currently used tests for the presence of HIV antibodies in the body. Infections by different routes may infect different subtypes. But they can all be detected in antibody tests after the window period. At the same time, the amount of HIV entering the body will not affect the length of the window period. In other words, whether it is blood transfusion infection, breast infection, breastfeeding infection or other forms of infection, no matter how much HIV is infected, a positive antibody reaction will generally appear after the window period. With very few exceptions, there is no such thing as a long window period for some specific infections and a short window period for others.

About the length of the window period

There is currently no internationally and domestically recognized window period. The more popular ones are 6 weeks, 3 months and 6 months respectively. Among them, what I personally approve of is the professor’s 6-week theory. She is also an authority in the world and has clinical experience in more than 1,000 cases. No one will talk about this life-threatening matter casually. When many friends ask her this question, she has always been categorical, which shows that she has a firm understanding of her own affairs. How confident the theory is; in addition, on the one hand, the current detection reagents are sensitive enough, so there are only false positives, but never false negatives. On the other hand, we are all healthy young people. Why can’t we still produce antibodies to such a powerful virus in a month and a half?

Of course, as far as I know, everyone will have a review every 3 months, which is still necessary. At least most hospitals and epidemic prevention stations still insist on the three-month statement. Add 100% sure insurance to your health and give yourself 100 peace of mind. As for some doctors who still insist on 6 months, I first doubt their professional level and research attitude, and they dare not take responsibility. This is to insure themselves. He will not be wrong. If he says he wants 1 The year is even more correct. In addition, there is a very important "psychological window period". Since there is no absolutely clear window period in medicine, some friends are still undergoing examinations even 2 years later. I wonder how long they will have to wait in fear to find their way home!

Therefore, everyone should determine a clear psychological window period for themselves after careful consideration. In other words, if you are still negative after this period, you can be completely relieved. The next task is how to return to the previous state. Physical and psychological state, return to your previous life. Otherwise, there will be no end to worry and suspicion. No one wants to live in the shadow of HIV forever, right?
