MAIN EDUCATIONAL POINTS from G213

  1. Along with clinical symptoms, a properly prepared, stained, read and rapidly reported Gram stain can provide information to aid the clinician– to initiate appropriate treatment while waiting for culture results.
  2. Neutrophils are commonly observed in Gram stains, especially from infected wounds. Their presence is an indicator of an active inflammatory process, useful in assessing the clinical significance of isolates.
