The presence of flagellated pyriform protozoa, or trichomonads, indicates a positive test result. These ovoid-shaped parasites are slightly larger than polymorphonuclear leukocytes (PMNs), a type of white blood cell, and may be identified by their ameboid mobility. Trichomonads cause an inflammatory reaction; therefore, a large number of PMNs are usually present and correlate with the severity of infection.
