Schistosoma antibody screening (serum/plasma)

What This Test Measures

The test detects antibodies (IgG and IgM) produced by your immune system in response to *Schistosoma* parasites. These antibodies appear after infection and can linger for years. The test is qualitative, meaning it only tells you if antibodies are present, not their exact amount.

Why It’s Ordered

Your healthcare provider may order this test if you have symptoms like fever, rash, or organ damage (e.g., liver, bladder) that could suggest schistosomiasis, or if you’ve traveled to regions where the parasite is common. It’s also used as a screening tool for people at higher risk.

What to Expect Before the Test

No special preparation is needed. You’ll have a small needle inserted into a vein (usually in your arm) to draw blood. The process takes about 5 minutes, and you may feel a brief pinch. If you’re nervous, let your provider know.

What the Results Mean

A positive result means antibodies were found, suggesting possible past or current infection. A negative result means no antibodies were detected, but this doesn’t rule out infection if symptoms are present. Follow-up tests (like confirmation assays) may be needed for further evaluation.
