Sensitivity and specificity of rapid antibody diagnostic test for diagnosis COVID 19 in pediatric patients

ABSTRACT

Objective: Aim of this observational is to evaluate the sensitivity and specificity a rapid diagnostic test for COVID-19 for screening COVID-19 pediatric patients. Study Design: 179 Patients under 18 years old with a history of COVID-19 symptoms, and who underwent PCR and/or reference antibody testing for COVID-19. Results: The sampel of this study consisted of 179 patient who 100 sunject with reactive in rapid antibody diagnostic test COVID 19 which consisting of 40 subject positive SARS-CoV2 PCR swab examination and 60 subject negative SARS-CoV2 PCR swab examination. The patient with nonreactive result in rapid antibody diagnostic test COVID 19 which consisting of 19 subject positive SARS-CoV2 PCR swab examination and 60 subject negative SARS-CoV2 PCR swab examination. The sensitivity of the test was 67%. Specificity was 50%. There was substantial agreement between SARS-CoV2 PCR results and a rapid antibody diagnostic test COVID 19. Conclusion: The current evaluation of antibody-based system shows low sensitivity and low specificity result. © 2022 Universidad Tecnica de Manabi. All rights reserved.
