Sensitivity and specificity of antigen testing were considerably poorer.

Sensitivity improved to 78.6% (49.2%-95.3% for those with active lesions. Using CT as the gold standard, the sensitivity and specificity of antibody testing for identifying NCC were 54.5% (36.4%-71.9% and 69.2% (52.4%-83.0%, respectively.

Elizabeth clinic with CT-confirmed NCC was 37% (95% CI: 27%-48%. The proportion of persons with epilepsy attending St. Four randomly chosen, consenting participants were transported each week to Mthatha for brain CT scan. Blood samples were tested by ELISA for antibody and antigen for Taenia solium. Epidemiological data were collected by local study staff using a standardized questionnaire.

Elizabeth's Hospital in Lusikisiki, Eastern Cape Province, between July 2004 and April 2005 were invited to participate. The second objective was to estimate the accuracy of serological testing in detecting NCC in these outpatients and characterize sources of disagreement between serology and neuroimaging.All out-patients aged 5 or older attending the epilepsy clinic of St. The first objective of this pilot study was to estimate the prevalence of NCC in epilepsy outpatients from an area of South Africa endemic for cysticercosis. While the limitations of serological testing in identification of NCC are well known, the characteristics of persons who are misdiagnosed based on serology have not been explored.
