Description
Bacteriological examination of throat material for Streptococcus pyogenes (Group A β-hemolytic Streptococcus) is the gold standard for diagnosing acute bacterial tonsillopharyngitis. It allows detection of the pathogen, determination of its quantity in the biological sample, and assessment of antibiotic susceptibility.
If the result is positive, an antibiotic susceptibility test with MIC (minimal inhibitory concentration) is performed to help the physician select effective antibacterial therapy.
When and who needs the test?
- in cases of recurrent tonsillitis or pharyngitis;
- before prescribing antibiotics to confirm the bacterial etiology of the disease;
- after contact with patients diagnosed with scarlet fever;
- for epidemiological monitoring in childcare or educational institutions;
- prior to ENT surgical interventions;
- in patients with suspected rheumatic fever or post-streptococcal glomerulonephritis.
Biological material
- Various types of biological material depending on the test
Preparing for pharyngeal swab taking
