Schistosoma antibody, serum/plasma (qualitative or semi-quantitative screening)
This test detects antibodies in your blood that may indicate past or current exposure to *Schistosoma*, a parasitic worm that can cause infections like schistosomiasis.
["This test helps identify if your immune system has reacted to a parasitic infection from *Schistosoma* worms."]

Why This Test Might Be Ordered
Your healthcare provider may recommend this test if you have symptoms like fever, rash, joint pain, or digestive issues that could be linked to a parasitic infection. It’s also used in areas where schistosomiasis is common to screen for exposure, especially in travelers or individuals with risk factors like exposure to contaminated water.
What to Expect Before the Test
No special preparation is needed. You’ll provide a blood sample, usually drawn from your arm. The test checks for antibodies in your serum or plasma, which your body produces in response to the parasite.
What the Results Mean
A positive result suggests your immune system has detected *Schistosoma* antibodies, meaning you likely had exposure at some point. A negative result means no detectable antibodies were found, but this doesn’t rule out past exposure or infection. Results are qualitative (yes/no) or semi-quantitative (approximate levels), so they don’t indicate the severity of infection.
Next Steps and Follow-Up
If your results are positive, your provider may order additional tests (like stool or urine exams) to confirm the infection or guide treatment. If negative, they may recommend retesting if symptoms persist or if you’ve had recent exposure to high-risk areas.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Schistosomiasis is a chronic infection caused by parasitic worms that live in freshwater. Antibody tests help diagnose exposure but aren’t definitive for active infection. Early detection can guide treatment to reduce complications like kidney or bladder damage. This test is particularly useful in endemic regions or for travelers returning with symptoms.
