The availability of an H.I.V. test as easy to use as a home-pregnancy kit is yet another step in the normalization of a disease that was once seen as a mark of shame and a death sentence.
The OraQuick test, by OraSure Technologies, uses a mouth swab and gives results in 20 to 40 minutes. A previous test sold over the counter required a user to prick a finger and mail a drop of dried blood to a lab.
Dr. Anthony S. Fauci, the longtime AIDS researcher and director of the National Institute of Allergy and Infectious Diseases, called the new test a “positive step forward” and one that could help bring the 30-year-old epidemic under control.
