Overview

David J, Konopásek P. Role of rapid antigen detection tests in paediatric practice

Accurate differentiation between viral and bacterial pharyngitis is crucial for the targeted use of antibiotic therapy and for limiting the rising problem of antibiotic resistance. Clinical signs alone are insufficient to reliably determine the etiology, which is why rapid antigen detection tests (so-called streptests) are used in paediatric practice. The streptest represents a quick and generally useful diagnostic tool when appropriately indicated. Its results must be interpreted in the context of the patient’s overall clinical condition, the epidemiological situation, and other relevant factors. At the same time, testing should be avoided in situations where it may detect only asymptomatic carriage, as this could lead to inappropriate antibiotic prescribing.
