MÉTODOS: Se incluyeron 497 personas en Santiago de Chile: 153 tenían resultados positivos para el VIH, y la situación de las restantes 344 era desconocida. OBJETIVO: Comparar la sensibilidad y la especificidad de una prueba oral rápida con las del análisis de inmunoadsorción enzimática (ELISA) para la detección del VIH en Santiago de Chile, Chile hacer un seguimiento del número de participantes en el estudio que regresan para saber los resultados del ELISA y analizar las percepciones de los participantes con relación a la prueba oral rápida en comparación con el ELISA. Key words: HIV infections, diagnosis AIDS serodiagnosis HIV seroprevalence clinical laboratory techniques disease prevention Chile. ORT provides quicker results, potentially ensuring that more people receive them, and does not require handling of or exposure to potentially hazardous blood products. ORT oral swabbing appeared more practical and less invasive than drawing blood for the ELISA.ĬONCLUSIONS: The ORT and ELISA were statistically equal in specificity and sensitivity. Participants positively perceived ORT as having reduced both waiting time and anxiety over obtaining their test results. Of the 344 participants whose HIV status was unknown at the start of the study, 55 failed to return for their ELISA results. The ORT showed a sensitivity of 98.4% (95.7%≩9.9%, 95% Confidence Interval) and specificity of 100%. RESULTS: The ELISA reported 184 (37%) of the 497 participants as being "positive" for HIV antibodies the ORT showed 181 (36.4%) as being "reactive" for HIV. Qualitative data were collected from 22 participants to compare perceptions of the testing experience with ORT versus ELISA. Participants were tested for HIV using both the ELISA and the ORT to examine and compare specificity and sensitivity. METHODS: A total of 497 people were recruited in Santiago, Chile: 153 had previously tested positive for HIV, and 344 were of unknown status. OBJECTIVE: To compare the sensitivity and specificity of an Oral Rapid Test (ORT) to that of the Enzyme-Linked Immunosorbent Assay (ELISA) for HIV testing in Santiago, Chile to track the number of study participants returning for ELISA testing results and to analyze the participants' perceptions of the ORT compared to the ELISA.
