Abstract:
:Test strips for the detection of antibodies to human immunodeficiency virus type 1 were investigated using specimens from risk groups in Thailand (141 reactive; 445 nonreactive) in a local Thai laboratory. The diagnostic sensitivity and specificity were both 100%. Using a set of seroconversion panels, the sensitivity of the test strips was within the range of sensitivities obtained with enzyme immunoassays. The test was developed for performance at decentralized settings under nonlaboratory conditions. :During December 1992-January 1993, the Thai Ministry of Public Health collected blood samples from populations at high risk of HIV infection (prostitutes and men attending sexually transmitted disease clinic). All these samples were evaluated for HIV infection by enzyme immunoassay and, if positive, confirmed by the Western blot. There were 141 HIV-1 reactive samples. In a blind study, laboratory personnel of the Venereal Diseases and Control Center in Chonburi, Thailand, later analyzed 586 serum samples with test strips (Sero-Strip HIV; Saliva Diagnostics Systems; Singapore). The strips have a synthetic peptide representing a highly conserved region of viral transmembrane glycoprotein, gp41. This peptide captures HIV-1 antibodies. Three investigators read the test strips independently. There were no discrepant readings among them. The test strips were also evaluated under nonlaboratory conditions of decentralized settings: exposure for 21 weeks at 45 degrees Celsius, exposure for 20 weeks at 22 degrees Celsius, and 98% relative humidity. The results of the test strips correlated completely with those of the conventional immunoassays. Thus, there were neither false positive nor false negative reactions. In conclusion, these test strips can be used reliably in non-air-conditioned tropical settings.
