Unacceptable Condition
Stool specimen:
More than 1 stool specimen received on the same day.
Stool specimen contaminated with urine.
Corneal scraping:
1) Do not smear across the entire slide. This will reduce the chance of picking up the organism. Smear within the circle.
2) Do not stick 2 slides with scotch tape together (with sample in between). This will create unnecessary safety hazard for staff handling slides.
