Special Instructions

Exam includes smear only, and is designed for a quick preliminary interpretation of the flora contained in a specimen. It should not be used as a replacement for culture, as smears are much less sensitive and may not detect all pathogens present. Most culture requests include a direct smear and do not require a gram stain to be ordered separately.
