A hake allergy test uses a blood sample to measure allergen-specific IgE antibodies against hake proteins. Hake is a commonly eaten white fish, and fish allergy is often linked to a muscle protein called parvalbumin that appears across many species. Because of that shared protein, a person who reacts to one fish may react to others. The test is a screening tool for suspected fish allergy, not a diagnosis by itself. A provider may order it after a reaction to hake or as part of a broader fish and shellfish panel.

• Hake-specific IgE Antibodies produced against hake proteins; used to assess sensitization to hake.

• People who develop hives, itching, or swelling after eating hake or other fish
• Individuals with tingling or itching in the mouth after fish
• Those with digestive upset, vomiting, or diarrhea after fish
• People with eczema or skin reactions who suspect a fish trigger
• Anyone who has reacted to related fish species and needs testing

• No fasting is required for this IgE allergy test
• The blood sample can be collected at any time of day
• Tell the provider about all medications you take
• No special diet is needed beforehand

Results are reported as an IgE level or class for hake. An elevated value may indicate sensitization, but sensitization does not always mean a person will react when eating hake. A low or undetectable level makes a true hake allergy less likely, though it does not rule out allergy to other fish. Because many fish share the parvalbumin protein, a provider may consider cross-reactivity across species. Discuss all results with a healthcare provider before changing your diet.
