Allergen, Food, Casein (Cow's Milk) IgG
Also known as: CASEIN IGG
Use
The test measures the levels of IgG antibodies specific to casein, a protein found in cow's milk. It is used to assess allergen-specific IgG antibody levels in patients, which may indicate an immune response to casein. Values less than 2.00 mcg/mL represent absent or undetectable levels of allergen-specific IgG antibody.
