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.
