Parasite in Stool: Symptoms, Causes, and How to Get Tested

Parasite in stool can present with persistent diarrhea, abdominal cramps, bloating, nausea, weight loss, or fatigue. A range of parasites—such as Giardia, Entamoeba histolytica, and various intestinal worms—are often transmitted through contaminated water or food, or through poor hygiene. If you notice these symptoms, testing is the fastest way to determine whether a parasite in stool is the cause and to guide appropriate treatment. Learn when to seek care and what to expect from testing with practical steps you can take today. Testing for a parasite in stool usually involves collecting stool samples for analysis. A clinician may request samples on several days to improve detection. Tests can include microscopic examination to spot eggs or cysts, antigen tests for specific parasites, and PCR-based methods that detect parasite DNA. Results help clinicians tailor treatment, which can range from single-dose medications to short or longer courses, depending on the parasite identified. If you’ve recently traveled, drank questionable water, or eaten foods from high-risk sources, share this history with your provider to inform the test chosen.
