Explanation

Stool collection: use a clean dry bedpan or toilet specimen 'hat' to keep stool free of urine and toilet water (both can invalidate testing). Transfer a portion (about 1 tablespoon for routine; more for ova/parasites) using a tongue blade into the labeled container, cap, and send promptly per order. Wear gloves. Contamination (c, d) invalidates testing; bare hands (b) violate Standard Precautions. Document time, characteristics (color, consistency, blood).
