Throat: no group A, C, G β-hemolytic streptococcus or Arcanobacterium haemolyticum – Shipped February 2014
The challenge was sent to category A, B, and C laboratories. The sample was a simulated throat swab obtained from a 10 year old patient with pharyngitis.
Laboratories were expected to report the sample as culture negative for specific pathogens.
MAIN EDUCATIONAL POINTS from M134-1
- Negative reports from throat swab cultures should always be pathogen specific (eg. No Group A, C, or G streptococci isolated) so that clinicians know exactly what the laboratory looked for.
- Organisms that are commensals in the throat should not be reported as this may be clinically misleading, resulting in inappropriate and/or unnecessary treatment.
