A casein allergy test checks for an allergic response to casein, a protein in milk and dairy products. It is usually ordered when someone has symptoms such as hives, stomach upset, or breathing problems after eating dairy, and the cause is unclear.

What it measures

  • Casein-specific IgE — Antibodies made by the immune system that target casein; higher levels may suggest allergy.
  • Total IgE — A general measure of allergic tendency, not specific to casein.
  • Milk protein panel (optional) — May include other milk proteins such as whey to compare reactions.

Who it is for

Primary care clinicians, allergists, and pediatricians typically order this test. It is often used when a milk allergy is suspected but the history is not clear.

Preparation

No fasting or special preparation is required. Tell your clinician about any medications you take, especially antihistamines, as they may affect results.

Results and what they mean

Results are reported as a level or class for casein-specific IgE, often alongside total IgE. A clinician interprets these numbers with your symptoms and history; a high level alone does not confirm an allergy. This is general information, not medical advice.

Requesting the Casein Allergy Test in Delaware

Order online, choose a certified collection site in Delaware, and review results through a secure portal. No referral is required, and orders are processed confidentially. Access across Mid-Atlantic is densely built, so confirming a site ahead of time is worthwhile.

Frequently asked questions

Does a positive result mean I am allergic to milk?

Not always. Some people have positive IgE levels without symptoms. A clinician uses your history and may recommend other tests.

Can I take antihistamines before the test?

Antihistamines may reduce IgE levels and affect results. Ask your clinician whether to stop them and for how long.

How is this different from a lactose intolerance test?

Lactose intolerance involves difficulty digesting milk sugar, not an immune reaction. This test looks for an immune response to casein protein.

Is this test safe for children?

Yes, it is a standard blood draw. Discuss any concerns with your child's clinician.
