Comments
Certain drugs and compounds will render stool specimens unsatisfactory for examination. Among these are antidiarrheal compounds (kaolin-pectate, etc.) antibiotics, antacids, bismuth and barium. Specimens used for parasitologic examination should be obtained before these compounds are used or collection must be delayed until the effects have passed (antiparasitical agents, 10 days to 3 weeks; others, 7-10 days).
