RESUMEN
México ocupa el 13o lugar en número de casos de SIDA a nivel mundial y el 3o en el Continente Americano, con un número estimado de 80,000. La disponibilidad tanto de medicamentos antirretrovirales efectivos en su tratamiento como de pruebas sensibles y específicas para medir la carga viral al HIV-1 ha modificado favorablemente el panorama de este padecimiento. Sin embargo, la correcta interpretación de los resultados de estas pruebas es fundamental para su adecuada utilización.
En la interpretación de estas pruebas es importante considerar las numerosas variables preanalíticas, analíticas y posanalíticas que pueden afectarlas y considerar la manera más adecuada de tomar y conservar las muestras para estudio, el efecto de variaciones y numerosas patologías sobre sus valores, así como la elección de la prueba más adecuada en términos de precisión, reproducibilidad, sensibilidad, especificidad, costo, facilidad de realización y su interpretación en términos logarítmicos y no aritméticos.
