Objective:

We aimed to realize a verification of the performance of the rapid serological tests used in Risaralda department.

Methods:

Analytical, cross-sectional study. Serum samples from health workers in Pereira city, who had a clinical and epidemiological suspicion for SARS-CoV-2 were included. The processing and validation of the tests was carried out at Universidad Tecnológica de Pereira. Sensitivity and specificity of rapid IgM / IgG sero logical tests were calculated using RT-PCR as the gold standard test.

Results:

144 samples of health professionals were included. Rapid serological tests useful to identify or rule out the presence of IgM and IgG antibodies, especially in symptomatic patients, in whom the onset of symptoms is longer than 11 days.

Discussion:

The use of rapid tests is increasing, not only due to the speed of their results, but also due to the low associated costs and the need to identify non-susceptible patients, who must prioritize their return to work activities in the community as part of the economic reactivation of Colombia. It is necessary to confirm the adequate performance of the test to increase the probability of an adequate classification before proceeding with the routine use of this test.
