Assessment of the heat stability of seven rapid HIV assays.

Human Immunodeficiency Virus Rapid Diagnostic Tests (HIV RDTs) are robust, quick to perform, effective diagnostic tools. The stability of seven commonly used RDTs for detecting antibody to HIV was assessed during exposure to temperatures above 30°C, the usual maximum recommended by manufacturers. The aim of the study was to determine if HIV RDTs retain their testing outcomes after exposure to higher temperatures.

Assessing proficiency of interpretation of rapid human immunodeficiency virus assays in nonlaboratory settings: ensuring quality of testing.

Rapid antibody tests for the detection of human immunodeficiency virus (HIV) offer an effective means of providing a timely result of HIV serostatus to individuals. The increased use of rapid HIV antibody tests outside the laboratory has highlighted the need for new, cost-effective quality assurance methods to be developed for use in nonlaboratory-based and resource-limited settings. Photographed rapid HIV test results were used in a modified external quality assessment scheme to assess the interpretation proficiency and, therefore, to assess the feasibility of using this method as a basis for a quality assessment program for nonlaboratory-based testing.
