Ref. Range Notes

Interpretation:

A positive enzyme-linked immunosorbent assay result suggests current infection with Trichinella spiralis. Serology should be used in conjunction with clinical, epidemiologic, and other laboratory tests to establish the correct diagnosis.

The number of individuals showing positive results may vary significantly between populations and geographic regions.

Interferences and Limitations

Cautions: Antibodies to Trichinella spiralis may not be detectable until 3 weeks after the onset of infection. Therefore, negative results in suspicious cases should be followed by repeat testing in several weeks.
