What this test is

This test measures specific IgE antibodies in the blood that target casein, a protein that makes up about 80 percent of the proteins in cow's milk. It is used to help evaluate whether a person has a milk allergy, which is different from lactose intolerance.

What it measures

  • Casein-specific IgE — Reflects the level of allergic antibodies directed against casein protein.
  • Total IgE — Sometimes measured to provide context for allergic tendency, though not always included.
  • Milk protein components — May include other milk proteins like alpha-lactalbumin or beta-lactoglobulin if a broader panel is ordered.

What the test involves

A healthcare professional collects a small blood sample, usually from a vein in your arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this test when a person has symptoms such as hives, digestive upset, or breathing problems after consuming milk or dairy products. It can help determine whether those symptoms are related to an immune response to casein.

Preparation

No special preparation is typically required for this blood test, but you should follow the specific instructions provided by the collection lab. This may include avoiding certain medications or fasting, depending on the lab's protocol.

How results are reported

Results are reported as a level of specific IgE antibodies, often categorized from negative to high positive, along with a reference range. Reference ranges vary by laboratory, so your results should be interpreted in the context of the lab's own ranges and your clinical history.

Before you go

  • Whether any medications you take could affect the test results.
  • If fasting or other preparation is required before the blood draw.
  • How and when you will receive your test results.
