Reference Range

<1.00

Test Methodology

Fluorescent Microsphere Immunoassay

Interpretation

<1.00	Antibody not detected
≥1.00	Antibody detected

This assay utilizes the microsomal fraction of adult S. mansoni worms (MAMA) as antigen and is thus highly specific (99%) and sensitive (96%) for detection of infection caused by S. mansoni. Although the assay is also highly specific for infections caused by other Schistosoma species (S. japonicum, S. haematobium, S. mekongi), its sensitivity for these infections is lower (55%). Antibody levels do not correlate with intensity of infection.

Clinical Utility

This assay aids in the diagnosis of schistosomiasis.
