Why This Test Might Be Ordered
Your doctor may recommend this test if you’ve traveled to regions with high risk for schistosomiasis (e.g., Africa, South America, Asia) or if you have symptoms like skin rashes, fever, or digestive issues that could suggest infection. It may also be used to confirm a diagnosis after exposure or during treatment follow-up.
What to Expect Before the Test
No special preparation is needed. You’ll have a small needle inserted into your arm to draw blood. The process takes about 5 minutes. You may feel a brief pinch, but most people tolerate it well.
What the Test Results Mean
Positive results indicate the presence of *Schistosoma* antibodies, suggesting past or ongoing infection. Negative results mean no detectable antibodies, but this doesn’t rule out infection if symptoms persist. Results are used alongside clinical findings and symptoms to guide diagnosis.
Common Symptoms of Schistosomiasis
Infection may cause flu-like symptoms early on (e.g., fever, fatigue) or later lead to skin irritation, digestive issues (e.g., diarrhea), or urinary problems. Some people develop chronic inflammation in organs like the liver or bladder. Antibody tests help confirm infection even if symptoms are mild or absent.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
