Schistosoma antibody profile (serum/plasma) – Immunoassay Panel
This test measures antibodies to *Schistosoma* parasites, which cause schistosomiasis—a parasitic infection spread through freshwater contact. It helps diagnose past or current infection.
["This blood test checks for signs of exposure to parasitic worms that may have infected you."]

What Does This Test Measure?
The test detects specific antibodies (IgG and IgM) against *Schistosoma* species, including *S. mansoni*, *S. japonicum*, and *S. haematobium*. These antibodies develop after infection and can indicate exposure, even if symptoms are mild or absent. The panel may include different *Schistosoma* species-specific assays, depending on clinical context.
Why Might You Need This Test?
Your healthcare provider may order this test if you have symptoms like skin rashes, fever, or gastrointestinal issues (e.g., diarrhea, abdominal pain) after freshwater exposure. It’s also used in regions where schistosomiasis is common to confirm infection in travelers or residents.
Sample Collection and Preparation
A blood sample is drawn from a vein, usually in your arm. The blood is processed into serum or plasma for testing. Results are typically available within 1–3 business days.
What to Expect Before the Test
No special preparation is needed, but inform your provider about recent travel to high-risk areas or symptoms like itching, fatigue, or unexplained skin changes. Avoid alcohol before testing if instructed.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Positive results suggest past or current *Schistosoma* infection. High IgM levels often indicate recent infection, while IgG levels may persist for years. While antibodies don’t confirm active disease, they guide further evaluation (e.g., stool/urine exams for eggs) or treatment decisions. False positives can occur with cross-reactions, so confirmatory tests may be needed.
