The presence of AIDS can be checked by taking a blood test for HIV antibodies. A negative result for HIV antibodies will rule out the possibility of HIV infection. Another easy way to test for HIV is to use an HIV test strip. Some test strips are tested by blood, while others are tested by saliva or urine, which are relatively more convenient. If you buy the test strips from the proper sources, you can better rule out HIV. However, if you want to rule it out completely, an HIV antibody test is recommended. If you want to find out if you have HIV after a recent 1-2 weeks of possible HIV infection, it is very likely that you will not be able to find out if you have HIV antibody test at this time. This can be done in combination with the P24 antigen test, which is a 4th generation HIV antibody test, or a quantitative HIV RNA test.
