Objective:
Routine clinical diagnosis of Streptococcus pyogenes in pharyngitis is not always easy. The use in common practice of rapid diagnosis test (RDT), might offer a best control of the antibiotic treatments. The aim of this study is to present seven rapid diagnosis tests, to assess their feasibility and finally to determine the bacteriological correlation.
Method:
We propose to compare the results obtained with seven RDT, and to assess their interest in medical diagnosis for group A streptococcus pharyngitis. A prospective study was conducted for three months, a RDT was performed for children (n=75) between eight and fourteen years old presenting acute pharyngitis. Several throat sampling were performed to order cultures.
Results:
The group A streptococcus was isolated in 33% (n=25) of throat sampling. Comparing cultures results, and for all studied tests, we obtained comparable performances with manufacturer data, specificity upper than 94% and sensitivity upper than 88%.
Conclusion:
All assessed RDT may offer to physicians a decision-making tool for rapid diagnosis. However, because of its complexity, the agglutination test can be used only in pathology laboratories.

Streptococcal Pharyngitis
Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Automated Microbial Diagnostics
Rapid Identification of Pathogens
Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
