Rational and expanded use of rapid diagnostic tests for respiratory infections in Primary Care

Respiratory infections remain one of the leading causes for medical consultations in Primary Care, particularly in paediatrics, and they are also a common reason for antibiotic prescriptions. Rapid diagnostic tests (RDTs) enable the early identification of frequent respiratory pathogens, optimising clinical decision-making and supporting the more rational use of antibiotics. This document provides a brief review of the most commonly used RDTs in paediatric primary care: influenza, respiratory syncytial virus (RSV), adenovirus, Bordetella pertussis, and Mycoplasma pneumoniae. The importance of considering seasonal prevalence when interpreting results is highlighted. This document aims to be a useful tool for effectively incorporating RDTs into paediatric primary care, reinforcing evidence-based clinical decision-making.
