Allergen, Food, Soybean
Also known as: SOY
Use
This test measures the concentration of allergen-specific IgE antibodies to soybeans in the patient's serum. It aids in the diagnosis of soybean allergy and helps assess the risk of an IgE-mediated allergic reaction. Allergic reactions to soybeans can range from mild reactions like hives to severe reactions like anaphylaxis. Test results should be interpreted in conjunction with clinical history and other diagnostic tests.
Special Instructions
Not provided.
Limitations
Allergen results of 0.10-0.34 kU/L have undetermined clinical relevance and should be used by specialists. Although increasing ranges reflect higher concentrations of allergen-specific IgE, these may not directly correlate with clinical reactions or skin test results upon allergen exposure. A negative test does not rule out clinical allergy or the possibility of anaphylaxis. IgE concentrations do not imply the severity of clinical allergy.
