Clinical Significance

The ELISA technique for the detection of trichinella IgG antibody offers significant improvements in sensitivity compared to the widely-used Bentonite Flocculation (BF) and Latex Agglutination (LA) tests. An excretory-secretory antigen is employed to reduce nonspecific reactivity; however, crossreactivity with other parasitic antigens (e. g., strongyloides, filaria, malaria) may occur. Such crossreactivity is usually associated with results in the equivocal range. The trichinella antibody ELISA must be considered a screening test for trichinella exposure. The diagnosis of trichinosis requires a compatible patient history and supporting pathologic findings.
