Codfish Allergy Test in Massachusetts

A codfish allergy test checks your blood for antibodies that may indicate an allergy to codfish. It is usually ordered when you have had allergic symptoms after eating cod or other fish, or when your doctor needs to confirm a suspected fish allergy.

What it measures

Codfish-specific IgE antibodies — The main marker. Your immune system makes these antibodies if it reacts to codfish proteins.
Total IgE — A general measure of allergic antibody levels, sometimes included for context.
Other fish-specific IgE — Sometimes tested alongside cod to see if you react to other fish, like salmon or tuna.

Who it is for

This test is typically ordered by an allergist, immunologist, or primary care doctor for people who have had allergic reactions after eating codfish or who need to confirm a suspected fish allergy.

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 shows the level of codfish-specific IgE in your blood. A higher number may suggest a greater likelihood of allergy, but results must be interpreted by a clinician along with your symptoms and history. This is general information, not medical advice.

Can this test tell me if I outgrew a codfish allergy?

Is this test painful?

It is a standard blood draw, so you may feel a brief pinch when the needle goes in. The rest of the test is done in a lab.
