Schistosoma species 10 kDa Antibody, Serum, Qualitative

What This Test Measures

The test detects antibodies directed against a small parasite protein (about 10 kilodaltons) associated with Schistosoma species. Antibodies are proteins your immune system makes when it encounters an infection. Their presence can indicate that your body has been exposed to these parasites at some point.

Why Your Clinician May Order It

Your clinician may order this test if you have symptoms or a travel history that raise concern for schistosomiasis, an infection caused by parasitic worms. Symptoms can vary and may include rash, fever, abdominal discomfort, or blood in the urine or stool, depending on the stage and type of infection. The test can help support further evaluation.

How the Sample Is Collected

A small blood sample is drawn from a vein, usually in your arm. The serum portion of the blood is then separated and tested in the laboratory. The collection is a routine blood draw and typically takes only a few minutes.

What the Results Mean

A negative result makes infection less likely but does not completely rule it out, especially early after exposure or in people with weakened immune systems. A positive result suggests exposure to Schistosoma parasites and usually prompts additional testing, such as stool or urine examination, to look for the parasite directly. Because antibody tests can stay positive for a long time after an infection has cleared, your clinician will interpret results together with your history and other findings.
