What is this test?
This blood test looks for allergen-specific IgE antibodies directed against proteins in Alaska pollock roe, the eggs of Alaska pollock. It is a qualitative test, meaning the result is reported as positive or negative.
Why might I need this test?
Your clinician may order this test if you have eaten fish roe and developed hives, swelling, wheezing, vomiting, or other symptoms of an allergic reaction. It can also be used when your history does not clearly identify the food that caused a reaction.
How is the test performed?
A blood sample is collected and tested in a laboratory for IgE antibodies to Alaska pollock roe. The laboratory reports whether specific antibodies were detected.
How do I prepare for the test?
Fasting is generally not required for this test. Tell your clinician about any recent allergic reactions, food exposures, medications, and known fish or shellfish allergies before testing.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive result indicates IgE sensitization to Alaska pollock roe and may support a diagnosis of food allergy when you also have a compatible reaction after exposure. A negative result makes immediate allergy to this roe less likely, but it does not rule out every type of food allergy. Results should be interpreted by a clinician because cross-reactivity with other fish or seafood allergens is possible.
Short name
Alaska Pollock Roe IgE
