Yes. Since the virus attaches and hides itself within the white blood cells and cannot be seen, the test (called an HIV antibody test) will detect antibodies produced by your body to combat the HIV virus. The HIV antibody test needs approximately 3-6 months to accurately detect the presence of these antibodies, so it is advisable a person wait approximately three months after possible HIV exposure to get tested.

If the test is negative, it is recommended that you return in another 3 months for a second test, since sometimes it can take up to six months for HIV antibodies to show up. It is urged that an individual abstain from any risky behavior during these 3-6 months (called the window period) while waiting to be tested and waiting for results.
