Laboratory Findings
A blood test or muscle biopsy can identify trichinosis. Stool studies can identify adult worms, with females being about 3 mm long and males about half that size. Laboratory confirmation of Trichinella infection is most often by a blood test. In some cases a muscle biopsy may be performed.
A diagnosis of trichinellosis is made in patients whose signs and symptoms are compatible with trichinellosis, have a positive laboratory test for Trichinella antibodies, and who can recall eating raw or undercooked pork or wild game meat.
