Useful For

This assay uses 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.
