Can The Virus Be Detected If Tested For HIV-1-RNA During A Window?
Good afternoon … I want to ask … if during the HIV window you continue to check blood using HIV-1-RNA (Real Time PCR) … Can the virus be detected or vice versa … Thank you …
Thank you for asking at HealthReplies.com.
Windows HIV period is a period where an individual is infected with HIV and a time when the results of an HIV test are not positive despite being infected with HIV. So that in the window period, a person does not get a positive HIV test despite HIV infection, and the window period of each individual varies, between 10 days to 3 months. So, if someone is infected with HV, after 3 months most likely the HIV test will be positive because it has passed the windows period.
As HIV testing progresses and develops, the window period for HIV-infected patients can be shorter, and there is currently a fourth generation of HIV testing p24 Ag + Ab EIA which can be carried out on days 12-26 after infection. Or NAT RNA test that can detect HIV viirus on days 10-14 after infection. While HIV RNA PCR examination, can detect HIV infection in the 2-3 weeks after infection.
In connection with your question, if you do a PCR HIV test after 2-3 weeks of having risky sex, then if you are infected with HIV, the PCR results can be positive. With this PCR examination. Thus, if the PCR results are positive, then you are likely to be HIV positive. And if the results of an HIV test are negative, then you can repeat the examination after 3 months later with an antibody examination against the HIV virus.
Therefore, PCR testing can give positive results to patients infected with HIV where PCR tests are performed at week 2.
If the test results are negative, you should avoid factors causing HIV infection.
