The Swordfish Allergy Test is a blood test that checks for an allergic response to swordfish. It is typically ordered when a person has had allergic symptoms after eating swordfish or other fish, or when a doctor needs to confirm a suspected fish allergy.

What it measures

  • Swordfish-specific IgE — Antibodies that your immune system makes in response to swordfish proteins.
  • Total IgE — A general measure of allergic tendency, sometimes included for context.
  • Cross-reactive fish IgE — Antibodies that may react to similar proteins in other fish, such as tuna or salmon.

Who it is for

This test is usually ordered by an allergist, immunologist, or primary care doctor for people who have had allergic symptoms after eating swordfish or other fish.

Preparation

No fasting or special preparation is needed. You can eat and drink normally before the blood draw.

Results and what they mean

Results are reported as a number that indicates the level of swordfish-specific IgE in your blood. A clinician interprets this number along with your symptoms and history to determine if you have a swordfish allergy. This information is not medical advice; talk to your healthcare provider about what your results mean.
