title: Rapid HIV testing: a review of the literature and implications for the clinician.
abstract: HIV counseling and testing services are critical for individuals to access HIV prevention and treatment. Unfortunately, the standard HIV testing algorithm is complex and includes the use of a sensitive enzyme immunoassay (EIA), followed by a Western blot if the EIA is positive. This process can take 1 week or longer. Therefore, innovative approaches that incorporate simpler diagnostic algorithms are needed to reach the large number of individuals who are not aware that they are HIV-infected. Currently available rapid HIV tests have demonstrated sensitivities and specificities comparable to those of standard HIV testing without the requirements of sophisticated laboratory resources or highly trained personnel. These rapid HIV tests are increasingly being used in various clinical scenarios to decrease the number of missed opportunities for detection of HIV-infection. Their use is particularly applicable in specific clinical and nonclinical settings; public health settings; labor and delivery wards; in the management of occupational exposures; and in resource-constrained settings. The overarching goals of achieving wide implementation of rapid HIV tests are to increase the number of individuals who are aware of their serostatus, to improve entry of persons with HIV into prevention and care services, and to prevent further HIV transmission.
