Background objectives: Dengue fever is a mosquito-borne illness that affects millions of people worldwide every year. With no vaccination available, early detection and treatment is critical. One-hundred-twelve countries in the world pose a risk to travelers, particularly in metropolitan areas. Laboratory diagnoses vary according to objectives, resources, and schedule, with sensitivity and specificity must be balanced for effective testing.
Methods: The current work is a cross-sectional diagnostic study and samples from suspected patients of dengue was collected from May 15 to November 15 2023 and transported to laboratory, and RT-PCR and Dengue Duo Rapid test diagnosis techniques were used on 48 clinical samples included in this study.
Results: Blood was collected from suspected cases of dengue and subjected further to different molecular and serological parameters. Serum was separated from all 48 blood samples. RNA was isolated by silica column extraction method which is further utilized as a template for amplification and detection of dengue serotyping. Master Mix was prepared for the amplification and detection of dengue virus by Rotor-Gene Q Real-Time PCR Machine and further serological profiling of positive dengue cases was studied by conventional PCR.
Interpretation conclusion: Our laboratory effectively standardized an RT-PCR-based approach for molecular identification of dengue virus in clinical specimens. This adaptive technique which used numerous primer sets displayed good specificity and sensitivity in serotype detection. The technology provides for quick and reliable identification of dengue virus infections, allowing for targeted treatment and preventative actions for successful disease management in highly populated regions.
