Allergen, Food, Corn IgG
Also known as: CORN IGG
Use
This test is used for determining the levels of allergen-specific IgG antibodies to corn in the serum. Elevated IgG levels might indicate past or ongoing exposure to corn allergens and may help in evaluating patient responses regarding food allergens. However, IgG testing for food allergens is not commonly used to diagnose food allergies as these antibodies often indicate exposure rather than an allergic response.
Special Instructions
Please ensure proper specimen collection and handling according to the 'Allergen Specimen Collection Instructions.' Samples should be transported following specified storage conditions to avoid rejection due to hemolysis, icteric, or lipemic properties.
Limitations
This test has not been cleared or approved by the FDA. It measures IgG antibodies and is not suited to diagnose immediate-type hypersensitivity or typical food allergy, which are usually mediated by IgE antibodies. It should not be used as the sole basis for treatment decisions. Performance of this test was established by ARUP Laboratories, and it is intended for clinical purposes in CLIA certified laboratories.
