Allergen, Food, Oat IgG
Also known as: OAT IGG
Use
This test measures the IgG antibodies specific to oat allergens in the blood. It is used to assess a patient's exposure and antibody response to oat allergens, which is important for understanding allergic reactions and allergies related to dietary intake of oats. The presence of allergen-specific IgG antibodies helps in the evaluation of immune responses and can guide dietary management to avoid possible allergens.
Special Instructions
Ensure adequate volume for allergen testing by following the Specimen Collection and Handling Instructions. Specimen should be collected in a plain red or serum separator tube (SST). Transfer serum to an ARUP standard transport tube as soon as possible.
Limitations
The test measures IgG antibodies specifically for oat allergens; it does not diagnose an allergic disease or predict clinical symptoms upon exposure to oat allergens. Results should be interpreted in conjunction with clinical findings and other diagnostic tests. Hemolyzed, icteric, or lipemic specimens are unacceptable and will lead to rejection of the sample. Laboratory-developed test (LDT) status means it is not FDA-cleared or approved.
