Item Process
Specimen

5-10 mL blood in plain tube.

Method

EIA, immunoblotting.

Application

To support the diagnosis of cysticercosis when suggested by clinical findings and imaging studies.

Interpretation

The sensitivity of the test is high for patients with multiple cysts, but as low as 30% for patients with single cysts.
