Diagnóstico de laboratorio de COVID-19
Palabras clave:
COVID-19, CORONAVIRUS, INFECCIONES POR CORONAVIRUS, DIAGNÓSTICO, TÉCNICAS DE LABORATORIO CLÍNICO
Resumen
Más de 500 test o pruebas diagnósticas para COVID-19 se están comercializando en el mercado mundial o se encuentran en avanzada fase de desarrollo. En esta situación, sin precedentes, es importante comprender el tipo de ensayos disponibles así como su rol en el proceso diagnóstico. El diagnóstico preciso es clave en el manejo de la pandemia. Esto permite la adecuada identificación de los casos, lo cual habilita las medidas posteriores de control: búsqueda de contactos y aislamiento. En esta revisión describiremos el fundamento y la utilidad de los diferentes tipos de pruebas para diagnóstico etiológico disponibles. También estableceremos las condiciones preanalíticas necesarias para su realización, la sensibilidad y especificidad clínicas, así como la correcta interpretación y emisión de los resultados.
