          Abstract

          La pandemia por el SARS-CoV-2 persiste con toda su virulencia a pesar de haberse administrado 650.382.819 dosis de vacuna anti-COVID a nivel mundial. La prueba de referencia para la identificación de la infección es la reacción en cadena de la polimerasa con transcriptasa inversa (RT-qPCR). La utilidad de esta prueba puede disminuir al simplificar su resultado como positivo o negativo. Determinar el número de ciclos (Ct) en las pruebas RT-qPCR positivas puede ayudar en la toma de decisiones cuando se interpretan en el contexto clínico de los pacientes.

          Translated abstract

          The SARS-CoV-2 pandemic persists with all its virulence despite 650,382,819 doses of COVID vaccine worldwide. The reference test for infection identification is reverse transcription polymerase chain reaction (RT-qPCR). The usefulness of this test may be diminished by simplifying its result as positive or negative. Determining the number of cycles (Ct) in positive RT-qPCR tests can assist in decision-making when interpreted in the clinical context of patients.
