An ova and parasite test examines a specimen under a microscope to look for parasite eggs, called ova, and for the parasites themselves. When performed on urine, it is used to evaluate for parasites that can affect the urinary tract, such as those acquired from contaminated water or soil in certain regions. A healthcare provider may order this test when a person has urinary symptoms, blood in the urine, or a history of travel or exposure that raises concern for a parasitic infection. Results are screening information and are interpreted with symptoms and exposure history.

• Ova and parasites A microscopic examination of a urine specimen for parasite eggs and organisms that can cause urinary infection.

• People with blood in the urine, burning, or urinary symptoms of unclear cause
• Individuals who have traveled to regions where urinary parasites are common
• Those with exposure to contaminated fresh water or soil
• People with a weakened immune system and persistent urinary symptoms
• Anyone whose healthcare provider suspects a parasitic urinary infection

• No fasting is required for this test
• Collect a clean-catch urine sample as instructed by the lab
• A first-morning sample is sometimes preferred, and more than one sample may be requested
• Tell the lab about any medications, including antibiotics

If ova or parasites are seen, it may indicate an active parasitic infection, and the specific organism identified helps guide interpretation. A negative result means no parasites were seen in that sample, but because parasite shedding can vary over time, a single negative test does not always rule out infection, and repeat samples may be recommended. This test is a screening tool rather than a diagnosis. Discuss your result with a healthcare provider, who can advise on any further testing or evaluation.
