Dengue fever is a disease caused by the dengue virus (DENV). In actuality there are several techniques that are used for its diagnosis. The RT-qPCR test enables reliable results with high sensitivity and specificity, moreover unlike the ELISA NS1 test, it allows us to identify the serotypes od DENV. The objective of the current work was to design a proposal for the implementation of the RT-qPCR for their use as an early molecular detection test of DENV and its serotypes in the Public Health Reference Laboratory – DIRESA JUNÍN. The available bibliography on the primers and probes that are being used for the diagnosis and identification of DENV and its serotypes was reviewed. These sequences were evaluated using the “Nucleotide-BLAST” tool and based on the results the primer sequences forward GATTTAGCAACATTCTRGATGTCATGTT, reverse TTGCACCA ACAGTCAATGTCTTCAGGTTC and forward AGAGCAGATCTCTGATGAATAAC CAA, reverse TGCACCAACAGTCAATGTCTTCAGGTTC were proposed for the diagnosis of DENV-1 and DENV-2 respectively. The protocol for the standardization of the RT-qPCR test and the minimum conditions for its operation was elaborated and based of the infrastructure and equipment available in the laboratory. The steps to perform each activity were established in the protocols for receiving samples, aliquoting samples, extraction of viral RNA and the RT-qPCR test. Finally, a comparison was made between the results of the ELISA NS1 processed in the Reference Laboratory and the results of the RT-qPCR test reported un the NETLAB system during the period between September 2018 and August 2021. The results of the RT-qPCR have been shown to have higher sensitivity and specificity compared to the results of the ELISA NS1 test. These findings demonstrated the importance of the implementation of the RT-qPCR test as a molecular diagnostic tool for DENV and its serotypes in the Public Health Reference Laboratory – DIRESA JUNÍN.
