Interpretation of gram stains for the nonmicrobiologist

Abstract

If the laboratorian's interpretation is not consistent with the guidelines presented in [T1] [T2], the interpretation should be reconsidered or consultation should be sought. Possibly over- or underdecolorization has occurred. Although these guidelines give objective criteria for interpreting the most commonly encountered Gram stains, there will be exceptions. The quality of the reports and confidence in the reports will improve if consultation with another technologist occurs before reporting such findings.
