Hi, does anyone know what is the window period for elisa 4th generation test? I know 3 months is recommended, but a lot of article state that even 3 to 4 weeks (22 to 25 days) is enough to detect the antibody and antigen due to the tester is very sensitive now and detuned. Some said 25 days is only an average date (9 - 41days). But most article said that test after 4 weeks can be 95% accuracy. Is that true?
