How is trichinosis diagnosed?

Tests of stool samples do not work to diagnose this condition. Your doctor might decide you have trichinosis initially on the basis of your symptoms and on blood tests showing high levels of eosinophils, a type of white blood cell. Antibodies to trichinella spiralis do not show up initially, but later blood tests, often repeated, will find the antibodies and confirm the diagnosis.

In very rare cases, doctors might recommend a biopsy of tissue to confirm the diagnosis.
