Provides information to assist in interpretation of the test results

Method for identification of Ova and Parasites includes wet mount and trichrome stain. Due to the various shedding cycles of many parasites, three separate stool specimens collected over a 5–7-day period are recommended for ova and parasite examination. A single negative result does not rule out the possibility of a parasitic infection. The ova and parasite exam does not specifically detect Cryptosporidium, Cyclospora, Cystoisospora, and Microsporidia.
