RESUMEN
Resumen Por ser el Perú un país endémico de HTLV-1, es importante conocer la confiabilidad de las marcas comerciales para el diagnóstico más usadas en nuestro país. En el presente estudio, evaluamos dos marcas comerciales de pruebas de ELISA (Biokit y Wantai) para la detección de anticuerpos contra HTLV-1 frente a muestras peruanas. Ambas marcas comerciales fueron evaluadas frente a 242 sueros 123 positivos a HTLV-1 y 119 negativos a HTLV-1 (referencia inmunoblot). Se estimaron los parámetros de precisión diagnóstica. La sensibilidad, especificidad, VPP, VPN e índice de validez de Biokit fueron 100%, 93,2%, 93,8%, 100%, 96,6%; respectivamente y de Wantai fue de 99,1% para todos los parámetros. Concluimos, que la marca Biokit fue la más adecuada para ser usada en el Laboratorio de Referencia Nacional de Virus de Transmisión Sexual, VIH/SIDA de Perú.
ABSTRACT
Abstract As Peru is endemic to HTLV-1, it is important to know the reliability of the most used screening trademarks in our country. In the present study, we evaluated two brands of ELISA (Biokit and Wantai) for the detection of antibodies against HTLV-1/2 against Peruvian samples. Both brands were evaluated against 242 sera 123 positive for HTLV-1 and 119 negative for HTLV-1 (Reference Immunoblot). We estimated diagnostic accuracy parameters. The sensitivity, specificity, PPV, NPV and validity index of Biokit were 100%, 93.2%, 93.8%, 100%, 96.6%; respectively and Wantai were 99.1% for all parameters. We conclude that the Biokit brand is the most suitable for use in the National Reference Laboratory of Sexually Transmitted Viruses HIV/AIDS, Peru.
