Trichinella Antibody (IgG), ELISA
Test Summary
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, cross reactivity with other parasitic antigens (e. g., strongyloides, filaria, malaria) may occur. Such cross reactivity 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.
