Stool microscopy is a standard diagnostic tool for intestinal parasites.

The test identifies ova (eggs of helminths) and cysts (protozoan forms) in stool samples.

Clinical uses include:

Detecting protozoan infections (e.g., Entamoeba histolytica, Giardia lamblia).

Identifying helminthic infections (e.g., Ascaris, Hookworm, Trichuris).

Evaluating patients with diarrhea, abdominal pain, malnutrition, or anemia.

Supporting epidemiological studies in endemic areas.

Often performed alongside stool culture, hanging drop, and antigen detection tests for confirmation.

Analyte: Parasitic ova and cysts in stool.

Normal Result: No ova or cysts detected.

Abnormal Findings:

Ova: Presence of helminth eggs (e.g., Ascaris, Hookworm, Trichuris, Taenia).

Cysts: Protozoan cysts (e.g., Giardia, Entamoeba histolytica).

Trophozoites: May be seen in fresh samples (motile protozoa).

Clinical Use:

Provides a definitive diagnosis of intestinal parasitic infections.

Helps guide antiparasitic treatment and public health interventions.

Supports gastroenterology and infectious disease evaluations.
