Cysticercosis Antibody, IgG by ELISA
Also known as: CYST SER
Use
The Cysticercosis Antibody, IgG by ELISA test is used to detect the presence of IgG antibodies to Taenia solium in serum, which is critical when there is a clinical suspicion of cysticercosis. Detection of seroconversion between acute and convalescent sera is considered strong evidence of recent infection. The best indicator of infection is significant serological change between two appropriately timed specimens analyzed simultaneously in the same laboratory.
Special Instructions
Confirmation of positive ELISA results by the cysticercosis antibody IgG using a Western blot is recommended due to potential cross-reaction between cysticercosis and echinococcosis positive sera. Convalescent specimens should be received within 30 days of the acute specimen receipt, and proper marking of specimens as 'acute' or 'convalescent' is crucial.
Limitations
False-positive results can occur in patients with collagen vascular diseases, hepatic cirrhosis, schistosomiasis, and other parasitic infections. Cross-reactivity with echinococcosis positive sera is a known limitation of the test. Testing both acute and convalescent sera simultaneously in the same laboratory is required for strong evidence of infection.
