Self-testing for HIV can be done using HIV test strips, which can be purchased on your own and are more significant for screening for HIV. However, if you cannot buy the test strips yourself, or if you do not trust the regularity of the test strips, you can also go to the hospital to have a blood test, which is the most common method of testing for AIDS, although it requires the use of hospital tests. When a blood test is taken, it is usually to test for antibodies to AIDS. If you are likely to have recently contracted HIV, you can use the HIV antibody test in combination with the P24 antigen test to shorten the window period. In addition to the blood test, there are also urine and saliva tests, which are more accurate and reliable than the blood test.
