Abstract:
It is difficult to accurately distinguish pharyngitis caused by Group A Streptococcus(GAS) from other pathogens according to the clinical presentation alone, which cannot effectively guide the rational use of antimicrobials.The pharyngeal swab culture, rapid antigen detection test, nucleic acid test, and blood test can help definitively diagnose GAS pharyngitis.However, there are differences in different guidelines on who the laboratory test methods are intended for, interpretation of laboratory test results and so on.This article summarizes and analyses the laboratory diagnostic modalities and their characteristics, as well as recommendations for GAS pharyngitis in different guidelines to provide references for the clinical diagnosis, antimicrobial treatment, and further study of GAS pharyngitis.
