Allergen, Food, Soybean IgG
Also known as: SOY IGG
Use
This test measures allergen-specific IgG antibodies to soybeans (Glycine Max) to assist in diagnosing potential soybean allergies. The measurement of IgG can aid in understanding a patient's immune response to soy proteins, which is particularly useful in dietary modifications for patients with food sensitivities.
Special Instructions
Ensure that adequate volume is collected for allergen testing. Use a plain red or serum separator tube (SST), and separate serum from cells as soon as possible or within 2 hours of collection. Transfer the serum to an ARUP standard transport tube and refrigerate for transport.
Limitations
This test is not intended for diagnosing immediate allergic reactions to soybean proteins. It is important to interpret results in conjunction with clinical findings and other relevant tests. Values less than 2.00 mcg/mL indicate absent or undetectable levels of the allergen-specific IgG antibody. The test is not New York state approved, and the laboratory developed test (LDT) has not been cleared or approved by the FDA.
