Bear muscle showing the encysted larvae at 200x magnification. (CDC).

A diagnosis of trichinellosis is made in patients whose signs and symptoms are compatible with trichinellosis, have a positive laboratory test for Trichinella, and who can recall eating raw or undercooked pork or wild game meat.

Laboratory diagnosis of Trichinella infection is most often made by a Trichinella antibody test. In some cases a muscle biopsy may be performed.
