Allergen, Food, Milk (Cow's)
Also known as: MILK
Use
This test is used to measure allergen-specific IgE antibodies in the serum to detect an allergy to cow's milk. It helps in evaluating patients suspected of having an IgE-mediated allergic reaction. The test can assist clinicians to correlate allergy laboratory results with clinical history and in vivo reactivity to specific allergens. However, levels of allergen-specific IgE may not directly correlate with the degree of clinical response or skin testing results when challenged with a specific allergen. A negative test does not rule out clinical allergy or anaphylaxis.
Special Instructions
Not provided.
Limitations
The clinical relevance of allergy results measured at 0.10-0.34 kU/L is undetermined and intended for specialist use. The measured concentrations of allergen-specific IgE are reflective of increasing allergen presence but may not directly correlate with clinical symptoms or reactions. A negative IgE test may not exclude the possibility of a clinical allergic response or anaphylaxis. Therefore, test results should be interpreted in the context of clinical history and other diagnostic findings.
