Parasitology

Why Use the Parasitology Test?

Parasitology is a gastrointestinal test that evaluates stool for the presence of intestinal parasites, using microscopic examination. Though data for intestinal parasitic infection in the US is limited, some research has found one-third of stool specimens to be positive for parasites, peaking seasonally between July and October.

This test is an ideal analysis for patients with sudden changes in bowel pattern, especially those who have been traveling abroad, have been camping, or may have had exposure to untreated water.

The parasitology test can help reveal parasitic infections and enable you to target treatment protocols geared toward infection resolution.

About the Parasitology Test:

By using a simple at-home stool test, the Parasitology test is a direct examination of stool for ova and parasites (O&P) in order to determine the presence of parasites and/or their eggs in the gastrointestinal tract. O&P is considered the gold standard of diagnosis for many parasites. Add-on options for the Parasitology test include:

  • Enzyme immunoassay (EIA) for the identification of Cryptosporidium, Entamoeba histolytica, and Giardia lamblia, three of the most common parasites in the United States
