An infectious diseases specialist explains HIV testing. What kind of HIV tests are available, how should we use them, and when? How do laboratory-based tests compare to point-of-care HIV tests? What is the sensitivity and specificity of different HIV tests? What is the window period for each test, and how does that influence HIV testing algorithms? What if we want to exclude HIV infection? When should we repeat the test or use another one? How do we approach possible acute HIV infection versus chronic HIV infection or AIDS? As always, this video is primarily intended for clinicians, medical professionals, and students. I highly recommend you follow the links to the research articles I used as resources for this video. You will learn a lot. Good luck!
