Microscopic Examination (cont.) - Ova and Parasite Examination

In addition to normal specimen debris, the microscopic examination of fecal material may reveal the following:

1. Trophozoites and cysts of intestinal protozoa.

2. Oocysts of coccidia and spores of microsporidia.

3. Helminth eggs and larva.

4. Red blood cells (RBCs) which may indicate ulceration or other hemorrhagic problems.

5. White blood cells (WBCs), specifically polymorphonuclear leukocytes (PMNs), which may indicate inflammation.
