1. The best time to rule out AIDS
The best time to rule out AIDS is within three months. The test method is blood drawing Laboratory tests, saliva and urine tests can detect HIV antibodies after the window period. The time it takes for humans to develop antibodies varies from person to person. If the test is negative and you have recently had high-risk sexual behavior, you need to test again within three months.
2. What is the window period for AIDS
AIDS The window period refers to the period from when HIV is contracted to when HIV can be detected. The length of the HIV window period is mainly related to the method used for HIV antigen and antibody testing. The earliest AIDS detection method has an AIDS window period of up to three months. Using the latest HIV testing methods, the HIV window can be shortened to about 3-6 weeks.
3. What is the accuracy of the six-week HIV test
Fourth-generation reagents and third-generation reagents are commonly used for HIV testing in China. The P24 antigen can be detected in about 4-10 days after the virus is detected in a truly infected person. Antibodies are produced in the next 3-5 days after the antigen is detected. After 28 days, the P24 antigen slowly decreases, and the human body becomes infected at the beginning of HIV infection.It will appear, but the concentration at that time is very low, and the current window period is 2-6 weeks. The accuracy of HIV antibody testing at different times after high risk: 1 week is 22.6%, 2 weeks is 53.775%, 3 weeks is 84.1%, 4 weeks is 98.4%, 5 weeks is 99.45%, 6 weeks is 99.994%, 7 weeks Close to 100%, 8 weeks is 100%.

Therefore, in daily life, we should be careful not to mess up our private life and pay attention to personal hygiene.
6. How soon can AIDS be detected
Normal situation After someone is infected with HIV, it can be detected after the window period has passed. Different detection methods have different window periods. The most widely used is the third generation HIV antibody detection method. Its window period is about 6 to 8 weeks, and very few people need to wait 12 weeks to be able to detect that they have AIDS.
This ends the sharing of the best time for HIV testing and the earliest time for HIV testing. If your problem is solved, we will be very happy.
