Abstract
RODRIGUEZ PELIER, Cira et al. Effectiveness of a rapid test for the diagnosis of COVID-19 and its relationship with clinical symptoms. Rev haban cienc méd [online]. 2023, vol.22, n.1 Epub Dec 01, 2023. ISSN 1729-519X.
Introduction:
The detection of the SARS-CoV-2 virus, the causal agent of COVID-19, is decisive to reduce the spread of the current pandemic. Although the procedure of choice is the determination of the nucleic acid of the virus using the polymerase chain reaction, the availability of rapid, highly sensitive, and accurate tests is also necessary.
Objective:
To analyze the diagnostic validity of a SARS-CoV-2 antigen rapid diagnostic test for the detection of COVID-19 in the “5 de Septiembre” Polyclinic in Playa municipality.
Material and Methods:
A cross-sectional analytical study was carried out on 590 patients seen in the acute respiratory infections consulting room in the period from January to August 2021. The detection of the SARS-CoV-2 antigen was performed using a rapid test and it was confirmed by polymerase chain reaction.
Results:
The rapid antigen test had a high sensitivity (98.19%) and specificity (92.39%). The concordance of the results obtained from both tests was high (0.868). The most frequent reported symptoms were headache (51.69%), fever (39.15%), cough (37.16%), loss of taste/smell (34.06%), and runny nose (30.16%).
Conclusions:
The SARS-CoV-2 antigen rapid diagnostic test used for the detection of COVID-19 is valid and can be used in the diagnosis of the disease. Symptoms such as headache, fever, cough, loss of taste/smell, and runny nose were the most frequently reported in more than 30% of cases.
