Unique Identifier : AIDSLINE ICA10/94370245 AB OBJECTIVE: To assess sensitivity and specificity of salivary HIV-antibody tests as a surveillance method in young men entering the Royal Thai Army. METHODS: Paired serum and saliva specimens were collected from 21-year-old men enlisted by the Royal Thai Army in November 1993 from Chiengmai and Bangkok metropolitan areas. Saliva specimen was obtained using the Omni-Sal saliva collection device. Serum specimen was obtained by venipuncture. Serum specimens were tested using EIA1 (Abbott HIV-1/HIV-2) and GPA (Serodia; Fujirebio, Japan) assays. Reactive serum specimens were tested by Western blot assay (HIV Blot 2.2, Diagnostic Biotechnology, Singapore). Saliva specimens were tested by EIA1, GPA, and EIA2 (Detect-HIV HIV-1/HIV-2) assays. RESULTS: From a total of 1,295 men it was found that 107 men had seropositive for HIV-antibody. There were 9 false-positive cases by GPA in saliva and 1 false-negative case by EIA1 in saliva. Serum tests did not show any false result and were used as reference standard methods. Comparatively, saliva test methods yielded the following percentages of sensitivity/specificity: GPA 100/99.24; EIA1 99.07/100; and EIA2 100/100, respectively. Similarly, the percentages for predictive value of positive/predictive value of negative are: GPA 92.24/100; EIA1 100/99.91; and EIA2 100/100, respectively. CONCLUSIONS: Saliva specimen collection is easy to perform, non-invasive, safe to use, and thus, provides alternative method to blood collection. Preliminary test results demonstrated excellent sensitivity and specificity in the detection of salivary HIV-antibody by EIA assays. Consequently, it is suggested that at least two assays by identical or different salivary HIV-antibody tests be performed in HIV surveillance. Further study is still needed before the approaches could finally be implemented as alternative methods to serum assays.
