A test that detects the presence of HLA-B*5701. The HLA-B*5701 molecule is linked to hypersensitivity to the antiretroviral (ARV) drug abacavir. A person who tests positive for HLA-B*5701 should not use abacavir.
Industry:Health care
A test that uses low-dose x-rays to measure bone mineral density, including calcium content, in a section of bone. Dual energy x-ray absorptiometry (DXA) scans are used to detect osteoporosis and predict the risk of bone fracture.

Industry:Health care
A thread-like structure found within a cell. Chromosomes, which are made of DNA coiled around proteins, carry all of the genetic information essential to the life of the cell.
Industry:Health care
A topical preparation or substance used during sexual intercourse to kill sperm. Although spermicides may prevent pregnancy, they do not protect against HIV infection or other sexually transmitted infections. Irritation of the vagina and rectum that sometimes occurs with use of spermicides may increase the risk of sexual transmission of HIV.
Industry:Health care
A type of antibody test used to confirm a positive result on an HIV screening test. (The initial screening test is usually an enzyme-linked immunosorbent assay (ELISA) or, less often, a viral load test). The immune system responds to HIV infection by producing HIV antibodies. A Western blot can detect HIV antibodies in the blood, oral fluid, or urine.
Industry:Health care
A type of antigen-presenting cell found in many tissues throughout the body. Dendritic cells capture antigens with their threadlike tentacles and present the antigens to T lymphocytes (T cells), stimulating an immune response.
Industry:Health care
A type of antiretroviral (ARV) HIV drug. Nucleotide reverse transcriptase inhibitors (NtRTIs) interfere with the HIV life cycle in the same way as NRTIs. Both block reverse transcription. NtRTIs are included in the NRTI drug class.
