What this test is

This test measures the amount of allergen-specific IgE in the blood that reacts to catfish proteins. IgE is an antibody the immune system can produce in response to allergens, and its presence may support a diagnosis of catfish allergy when considered with a person's history and other findings. It is not used alone to diagnose an allergy.

What it measures

  • Catfish-specific IgE — Reflects the amount of IgE antibody in the blood that binds to catfish proteins
  • Total IgE (if included) — Reflects overall IgE level, which can be elevated in allergic conditions but is not specific to catfish
  • Other fish-specific IgE (if a panel is ordered) — Reflects sensitization to other fish species that may be relevant to dietary choices

What the test involves

A healthcare professional collects a small blood sample, usually from a vein in the 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 a person reports symptoms after eating catfish or other fish, such as hives, swelling, stomach upset, or breathing changes. It can also be used to help monitor known fish allergy over time, though it is interpreted alongside symptoms and other tests.

Preparation

Preparation is generally minimal, but specific instructions can vary by laboratory. Follow the collection lab's instructions about medications, fasting, or timing before the draw.

How results are reported

Results are reported as a numerical level of catfish-specific IgE, often with a qualitative interpretation such as negative, low, or elevated. Reference ranges and reporting formats differ by laboratory, so results should be interpreted in the context of the lab's own ranges and the person's clinical history.

Before you go

  • Whether any medications or foods should be avoided before the blood draw
  • How and when results will be shared with you and your clinician
  • Whether a panel of other fish allergens will be included in the same sample
