Clinical Significance
This assay is a qualitative test for the confirmation of specific IgG antibodies recognizing Taenia Solium, the agent causing Cysticerosis. Detection of antibodies to any 6 specific T.solium glycoprotein bands of molecular weight 50, 42-39, 24, 21, 18, and 14 kilodaltons is interpreted as a positive result. However, a positive result without reac- tivity to the 50 and 42-39 glycoprotein bands may reflect crossreactive antibodies induced by Echinococcus.
