The 3gAllergy Specific IgE Universal Food Allergens Profile is a blood test that is used to detect the presence of specific IgE antibodies to a range of common food allergens
When this test is required
The test may be requested when a patient has symptoms that may be indicative of a food allergy or when the cause of the patient’s symptoms is unclear. It may also be ordered as part of a comprehensive allergy workup.
What the Test Detects
The test measures the levels of specific IgE antibodies to a range of common food allergens, including milk, egg, peanut, tree nuts, soy, wheat, fish, and shellfish.
Preparation for the Test
No specific test preparation is required for this test. However, it is important to inform the healthcare provider of any medications, supplements, or herbal products that you are taking.
Sample Requirements
The sample required for this test is a blood sample, which is usually taken from a vein in the arm.
Additional Notes
It is important to note that a positive result on this test does not necessarily mean that the patient has a food allergy, as elevated IgE levels can be present in patients who are sensitized to a food but do not experience symptoms. Therefore, the test results should always be interpreted in the context of the patient’s clinical presentation and other diagnostic tests. Additionally, a negative result on this test does not rule out a food allergy, as some patients may have non-IgE-mediated food allergies or may be allergic to foods that are not included in the test.
