Quick answer
This test looks for IgE antibodies directed at hake proteins in a blood sample. It is used when someone develops hives, itching, or other symptoms after eating hake or similar white fish. A healthcare provider interprets the result together with your full detailed reaction history.
What this test measures
Hake is a mild white fish used in many cuisines, and like other fish it contains parvalbumin, a protein that is the most common trigger of fish allergy. Symptoms can include oral itching, hives, digestive upset, or more severe reactions. The test measures IgE antibodies that recognize hake proteins.
A routine venous blood draw supplies the serum for analysis. The laboratory reports hake-specific IgE, total IgE, and a graded class. Some panels include additional fish markers, such as cod or salmon, and parvalbumin, which help a clinician understand whether reactivity is likely to be broad across fish species.
Testing is often ordered after a reaction to hake or when a broader seafood workup is organized. Because fish allergy often persists, the laboratory finding is a useful piece of information for a healthcare provider who is advising on diet and precautions.
- Hake-specific IgE antibody
- Total serum IgE
- Parvalbumin IgE (major fish allergen)
- Cod IgE cross-reactant
- Salmon IgE cross-reactant
- Tropomyosin IgE cross-reactivity
- IgE reactivity class for hake extract
Why people order this test
- Assess symptoms that follow hake or white fish meals
- Determine whether reactivity extends to other fish species
- Support seafood avoidance guidance from a clinician
- Document sensitization before a supervised challenge
- Include hake in a broader seafood allergy panel
How to prepare
No fasting is required, and collection does not need to follow a meal. A blood sample is drawn at a laboratory. Follow the instructions provided by the laboratory.
Understanding your results
Results are usually reported within one to three business days. A detectable IgE level reflects sensitization to hake, and a healthcare provider interprets what it means alongside symptoms and eating history.

Frequently Asked Questions
Is hake allergy the same as cod allergy?
They are related. Shared parvalbumin can cause reactions across species, though some people react only to certain fish.
Does freezing or cooking make hake safe?
Neither reliably removes parvalbumin, so reactions to prepared hake remain possible.
Can adults develop a fish allergy later in life?
Yes. Fish allergy can first appear in adulthood even after years of eating fish without problems.
Do I need to eat hake before testing?
No. The test measures circulating antibodies and does not require recent exposure.
What sample does the test use?
A standard venous blood sample collected at a laboratory.
