ABSTRACT
BACKGROUND:
Rapid identification of Covid-19 in the paediatric emergency department is critical; Antigen tests are fast but poorly investigated in children.AIMS:
To investigate Sars-CoV-2 antigen rapid test in children.METHODS:
We compare the performance of LumiraDx with molecular tests in a paediatric emergency department.RESULTS:
A retrospective cohort of 191 patients with AT and PCR tests performed in the same episode was analysed; 16% resulted positive for Sars-CoV-2. Using the PCR test as the gold standard, we calculated antigen testing overall sensitivity of 94.1%, specificity of 91.9%, and NPV of 99.4%. Only one false-negative test was found.CONCLUSIONS:
AT may be helpful in the initial screening of patients at PED.Key words
