Summary A saliva test used to diagnose the human immunodeficiency virus (HIV), is comparable in accuracy to the traditional blood test, according to a new study led by the Research Institute of the McGill University Health Centre (RI-MUHC) and McGill University. The meta-analysis, which compared studies worldwide, showed that the saliva HIV test, OraQuick HIV1/2, had the same accuracy as the blood test for high-risk populations. The test sensitivity was slightly reduced for low risk populations. The study, published in this week's issue of The Lancet Infectious Diseases, has major implications for countries that wish to adopt self-testing strategies for HIV.
Critic: Well there is still no cue for hiv
Impact: This save money for hospital because instead on drawing blood you spit in cup
