The Trout Allergy Test is a blood test that checks for an allergic response to trout, a type of fish. It measures specific antibodies the immune system may make against trout proteins. It is usually ordered when someone has had symptoms after eating trout or other fish.

What it measures

  • Trout-specific IgE — Antibody level linked to trout allergy.
  • Total IgE — Overall allergy antibody level, sometimes included.

Who it is for

A doctor or allergist typically orders this test for people with suspected fish allergy or unexplained reactions after eating trout. It may also be used to help confirm or rule out trout allergy.
