I want to ask. I did a risky act in January 2015. And on April 20 2018, yesterday I did an HIV check and the results were non-reactive. do I need another test or not? and can you explain what is non-reactive?

Hello, briannn.000, thank you for asking HealthReplies.com.

HIV testing can use several methods, one of which is to detect antibodies against the HIV virus. Antibodies are proteins in the body that fight "diseases" that come to our body. If it is detected positive / reactive with an antibody test, then our body is fighting the virus, which indicates that a virus has entered our body. If it is detected that it is non-reactive, it indicates two possibilities: 1) no virus has entered our body, or 2) there is a virus but not enough antibodies have been detected during the examination.

After the virus enters the body, antibodies take a period of time to be detected by the device. This period is called the window period. Simply put, during the window period, it could be that the person is actually infected but the antibody test results are still inactive or negative because the amount of antibody cannot be detected by the equipment. The window period for an HIV antibody test (rapid antibody test) is usually 3 months. So, if you do the test within 3 months after you do a risky activity and the test result is non-reactive or negative, you should do another test in 3 months.

It should be understood that during the window period, virus transmission can occur. So, if you are not sure about your condition, you should avoid doing activities that have the risk of transmitting HIV, such as having sex without a condom, changing sex partners, sharing needles, etc. Also read about HIV / AIDS for additional information.

That's all, hopefully it's useful.
