What does the Cow's Milk Specific IgE test measure?

Q: Why is Cow's Milk Specific IgE measured?

A positive cow's milk sIgE supports, but does not establish, an IgE-mediated milk allergy in a child or adult with a consistent immediate reaction. In the absence of a compatible history it most often represents clinically silent sensitisation. Component testing and, where indicated, a supervised oral food challenge remain the arbiters of true clinical reactivity.

Q: What is the reference range for Cow's Milk Specific IgE?

The standard reference range for Cow's Milk Specific IgE is Class 0 (<0.35 kU/L) denotes no detectable sensitisation; semiquantitative Classes 1–6 grade increasing specific IgE.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

Cow's Milk Specific IgE (f2 Milk sIgE) is a clinical biomarker used in food-sensitivity-allergy assessment. Specific IgE to cow's milk is directed against caseins, beta-lactoglobulin, and alpha-lactalbumin. It is measured in 1 laboratory test on BiomarkersLabs.com.

Reference Range: Class 0 (<0.35 kU/L) denotes no detectable sensitisation; semiquantitative Classes 1–6 grade increasing specific IgE.

Functional medicine optimalNo 'optimal' concentration applies; the clinically desirable result in an asymptomatic person is undetectable (Class 0). Higher values raise the probability — not the certainty — of clinical allergy.

What is Cow's Milk Specific IgE?

Specific IgE to cow's milk is directed against caseins, beta-lactoglobulin, and alpha-lactalbumin. Sensitisation reflects prior allergen exposure and T-helper-2 class switching rather than disease per se; the detected IgE is the circulating counterpart of allergen-bound IgE on mast cells and basophils. Casein-dominant IgE tends to track persistent, heat-stable reactivity, whereas IgE confined to heat-labile whey proteins may accompany tolerance of baked milk.
