An Ova and Parasite test examines a urine sample for parasite eggs, larvae, or related structures. It is used when a parasitic infection of the urinary tract is suspected and is reviewed together with symptoms and other testing.

Quick answer
The Ova and Parasite test looks for parasite eggs, larvae, or cysts in a urine sample. It is requested when a urinary parasite infection is suspected, often alongside other urine studies and a clinical assessment. Detection depends on the organisms present in the sample, so results are interpreted with the person's symptoms and exposure history.
What this test measures
Parasites can occasionally involve the urinary tract, either as a primary infection or as part of a broader illness. The Ova and Parasite test uses microscopy to look for eggs, larvae, or other parasite structures in urine. Some organisms, such as Schistosoma species, can shed eggs into the urinary tract, which is one reason this test may be ordered.
A urine sample is collected and processed in the laboratory, where a trained technologist examines it under a microscope. The test may be combined with other urine tests such as a urinalysis or a parasite-specific assay. Because shedding can vary over time, a single sample might miss an infection, and repeat collections are sometimes requested.
The test is not a stand-alone diagnosis. A negative result does not fully rule out infection, and a positive result is interpreted with the person's travel, exposure, and symptom history. A qualified healthcare provider decides whether confirmatory testing or further evaluation is appropriate.
- Parasite eggs (ova) in urine
- Parasite larvae in urine
- Parasite cysts or trophozoites when present
- Schistosoma species eggs
- Trichomonas organisms when observed
- Microscopic sediment review
- Urinalysis components such as red and white blood cells when paired
Why people order this test
- Evaluate a suspected parasitic infection of the urinary tract
- Follow up on urinary symptoms after travel to endemic areas
- Investigate blood in urine when other causes are being excluded
- Support evaluation of persistent urinary irritation with a provider
- Confirm the presence of parasite structures seen on earlier testing
- Provide additional context alongside a standard urinalysis
How to prepare
A urine sample is collected at the laboratory or as directed, and no fasting is required. Follow the collection instructions carefully, since sample timing and handling affect the ability to detect organisms. Tell the ordering provider about recent travel or known exposures.
Understanding your results
Results are typically available within one to three business days. The report notes whether parasite eggs, larvae, or other structures were seen. A negative result does not entirely rule out infection, so a qualified healthcare provider interprets the finding with symptoms and exposure history.

Frequently Asked Questions
What does the Ova and Parasite urine test look for?
It looks for parasite eggs, larvae, and related structures in a urine sample using microscopy.
Why would a parasite be found in urine?
Some parasites can involve the urinary tract and shed eggs or other structures into urine. The test helps detect that possibility when infection is suspected.
Can one sample miss an infection?
Yes. Organisms may be shed intermittently, so a single negative sample does not fully rule out infection. Repeat collection may be recommended.
Do I need to fast for this test?
No fasting is required. Follow the laboratory's collection instructions, which address timing and sample handling.
What should I do if the result is positive?
A positive result should be reviewed by a healthcare provider, who can arrange confirmatory testing and discuss appropriate next steps.
