In some cases, urine and blood tests aren't as accurate as other forms of testing. It may also take a month or longer after being exposed to certain STIs for blood tests to be reliable. If HIV is contracted, for example, it can take a couple of weeks to a few months for tests to detect the infection.

The most accurate and reliable routinely used diagnostic HIV test is a laboratory test that can detect both HIV antibodies and p24 antigen. They are called combination or combo tests because they detect both substances. They are “fourth-generation” tests, with more advanced technology than the earlier generations.

Blood. Of all the body fluids that can transmit HIV, blood contains the highest concentrations of the virus. HIV may survive in dried blood for up to 5–6 days at room temperature.

HIV is usually diagnosed by testing your blood or a sample of cells taken with a swab from inside your cheek for the presence of antibodies to the virus. HIV tests vary in how soon they are able to detect infection. The time between when you get the virus and when it can be detected is called the window period.

However, touching blood where the virus is present will not lead to transmission. This can only happen if blood that contains the virus enters an open wound. For example, if a person with HIV has an open wound, and fluid from that wound enters an open wound on a person without the virus, HIV can be passed on.

To test for HIV, a sample of a person's blood is taken (either a vial of blood from a vein or a couple of drops of blood from a finger prick). The blood is either sent to a laboratory to be tested for HIV or, with rapid point-of-care testing, the blood is tested immediately for HIV at the location it was taken.

It can take 3-12 weeks for enough signs of the virus to show up on routine tests for the infection, which measure antibodies against HIV. A new kind of screening, called a nucleic acid test, can detect the virus itself during this early stage, but it's expensive and not usually used for routine HIV testing.

HIV is the virus that causes AIDS (acquired immunodeficiency syndrome). AIDS is the most advanced stage of HIV infection. HIV testing can detect HIV infection, but it can't tell how long a person has had HIV or if the person has AIDS. Why is HIV testing important?
