HIV virus usually weakens the body immune system and therefore one get exposed to so many disease.Immediately you test positive for this virus, the best thing to do is start taking the ARVs. There drugs will help to reduce replication rate of the virus and so the body can be able to mentain a certain level of immunity. It takes sometimes for one to test positive even after contracting the virus.It takes time for the body to make antibodies after it is exposed to HIV virus.The body react to the virus by forming antibodies.Different people make antibodies at different rates. The Window period for antibody tests is between 3 weeks and 3 months. Up to 95% of people will have antibodies after 6 weeks, and 99% of people will have antibodies after about 3 months. This shows that even if two people contract the virus on the same days, one may test positive earlier than the other.
There are two main tests that can be used to test the presense of HIV virus into the body. Mostly the virus is now visible after it replicate to release so many other viruses. An antigen/antibody test performed by a laboratory on blood from a vein can usually detect HIV infection 18 to 45 days after exposure.This test requires more blood and also time. It quite expensive since it requires use of more advanced laboratory equipments.
Antigen/antibody tests done with blood from a finger prick take longer to detect HIV. The virus can be detected after about 18 to 90 days after an exposure. This is the most common test in hospitals and laboratory. It is simply and easy to use and get accurate results. An antibody test can take 23 to 90 days to detect HIV infection after an exposure. Most rapid tests and self-tests are antibody tests. In general, antibody tests that use blood from a vein detect HIV sooner after infection than tests done with blood from a finger prick or with oral fluid. Please share.
