What this test is

This test detects specific IgE antibodies that your immune system may produce in response to codfish proteins. It is a blood test that can support the evaluation of a suspected fish allergy, but it is not used alone to diagnose a condition.

What it measures

  • Codfish-specific IgE — Reflects the level of allergic antibodies directed against codfish proteins.
  • Total IgE (if included) — Provides a general measure of allergic antibody levels, though it is not specific to codfish.

What the test involves

A healthcare professional collects a small blood sample from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this test when you have had allergic symptoms after eating cod or other fish, such as hives, swelling, or digestive upset. It can also be used to help monitor an existing fish allergy over time.

Preparation

No special preparation is usually required, but follow the instructions provided by the collection lab. Tell the lab about any medications you take, as some may affect test results.

How results are reported

Results are reported as a numerical level of specific IgE antibodies, often with a qualitative interpretation such as negative, low, or high. Reference ranges vary by laboratory, so your results should be interpreted in the context of your symptoms and the lab's own range.

Before you go

  • Whether any medications you take could affect the test results.
  • If there are any special preparation steps required by the collection lab.
  • How and when you will receive your test results.
