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

Patients should avoid multiple encounters to prevent exposure to potential allergens. Serum should be processed promptly, separating it from cells within two hours of collection. If testing for multiple allergens, refer to the comprehensive allergen specimen collection instructions provided by ARUP Laboratories.

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.
