What this laboratory test evaluates
Gluten (f79) IgE
This test measures the IgE antibody response to gluten, helping to identify potential gluten allergies. It's a precise lab test used alongside other clinical evaluations to diagnose food allergies. The test is especially useful in situations where skin testing isn't possible or advisable, such as with skin conditions, recent antihistamine use, uncooperative patients, or a high risk of severe allergic reactions.
What patients is this test right for?This test is ideal for individuals who may have a gluten allergy, especially if they have conditions or situations that make skin testing difficult or risky.
Understanding Your Results:A positive result indicates sensitivity to gluten but doesn't confirm an allergy. Not everyone sensitive to gluten will have adverse reactions upon consuming it. A thorough evaluation by a healthcare provider is essential to diagnose a gluten allergy accurately. This test is a step in understanding your body's response to gluten but should be part of a broader clinical assessment.
What type of sample is required for this test?0.3 mL serum.
