Schistosoma DNA (Quantitative) – Stool Probe
This test detects genetic material from the parasitic worm *Schistosoma* in your stool. It helps identify if you have an infection caused by these worms, which can live in freshwater environments.
["A stool DNA test for *Schistosoma* infection may help diagnose parasitic infections early, especially in areas where the parasite is common."]

What This Test Measures
The test looks for specific DNA sequences unique to *Schistosoma* parasites in your stool sample. These sequences come from the parasite’s eggs or adult worms, even if they haven’t been seen under a microscope yet. The probe detects these sequences using advanced molecular techniques to confirm infection.
Why It’s Done
Your healthcare provider may recommend this test if you live in or have traveled to regions where *Schistosomiasis* (a parasitic infection) is common, or if you have symptoms like abdominal pain, diarrhea, or fatigue that could suggest an infection.
How the Test Works
A small stool sample is collected, usually from multiple bowel movements over a few days. The sample is then analyzed in a lab to identify parasite DNA using a specialized probe that binds to the parasite’s genetic material, allowing for sensitive detection.
What to Expect Before the Test
No special preparation is needed, but you may be asked to collect stool samples at home or bring fresh samples to the lab. Avoid using certain cleaning products (like harsh detergents) that might interfere with the test.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Detecting *Schistosoma* DNA early is important because untreated infections can cause chronic inflammation, organ damage (such as the bladder or liver), and long-term health issues. This test can help confirm infection before symptoms appear or worsen, guiding treatment decisions.
