Johannesburg, 2018. / Background: Accurate HIV diagnosis is critical and can be life-saving. A Rapid Test (RT) is considered key to HIV prevention and management. Some studies have found RT to be comparable with ELISA whilst others have reported on lower sensitivity.
Aim and study design: The aim of this retrospective comparative descriptive study was to evaluate the sensitivity and specificity of the Tri-line HIV rapid test device in comparison to ELISA on patient records from Wits Oral Health Centre (WOHC) between 2014 and 2016
Method: The study population comprised records of patients older than18 months who had Tri-Line HIV RT and blood drawn for ELISA on the same day. Descriptive analysis of the data was carried out.
Results: The sensitivity of Tri-line was 80% (CI: 59-93%) and specificity was 100% (CI: 83-100%). The PPV was 100% (CI: 83-100%) and NPV was 80% (CI: 65-90%). ROC area of 0.9 at 95% CI was determined.
Conclusion: Due to a low sample size in this study a definitive conclusion could not be drawn. However on the basis of the results obtained, although the tri-line RT showed lower sensitivity it was shown to be a clinically useful test. / LG2018
