Interpretation
Positive:
Antibodies to Taenia solium (cysticercosis) detected. Confirmatory testing through the Centers for Disease Control and Prevention is recommended. False-positive results may occur in patients with other helminth infections.
Negative:
No antibodies to T solium (cysticercosis) detected. A negative result may not rule-out infection as the sample may have been collected prior to the development of a detectable level of antibodies. Sensitivity is negatively impacted by the presence of few cysticerci or location in areas less accessible to the immune system. Repeat testing on a new sample is recommended for patients at high risk of cysticercosis.
