I was tested for HIV and syphilis in the First People's Hospital of Yancheng City, Jiangsu Province. It was a serum test, and it was negative many times. Why do some doctors draw more blood and some doctors draw less blood? If you don't have two high-risk banks in these eleven months, you are excluded.

H has a window period. According to national standards, the longest window period is 12 weeks. No antibody positive can be detected in the window period, but it does not mean that there is no infection with H, and there may be no symptoms. If there are symptoms, it is not necessarily H infection. It is recommended to test every two weeks during the window period until the end of the window period to confirm whether it is infected. If you are not at ease, you can go to the CDC for real-name registration, free blood test or "1 group" to find free HIV test paper to protect your privacy at home; We must rely on scientific testing, and it is meaningless to doubt at will; I hope my answer can help you and adopt it; If you are satisfied with the answer, please choose it as the satisfactory answer! Thank you!
