About this test

This test checks your blood for IgE antibodies to sheep milk. Sheep milk proteins are similar to cow’s milk proteins, and the two can cross-react. A positive result shows sensitization, which is not the same as an allergy. There is nothing to do ahead of your visit.

For adults 18 and older. Test availability varies by lab location.

Who should take this test?

Adults often choose it after a reaction to sheep milk products, or to bring a result to an allergist, when they want to check for sensitization to sheep milk.

What does this test measure?

The result shows whether you are sensitized to sheep milk. With your history, it can help an allergist or other healthcare provider decide whether further evaluation makes sense.

Sheep milk-specific IgE
IgE is the antibody involved in allergic reactions. This marker is the amount of IgE in your blood that recognizes sheep milk, reported in kU/L. A level above the lab’s reference range means sensitization, not necessarily allergy.
Why it’s measured: To see whether you are sensitized to sheep milk, read with your history by an allergist.

What your results tell you

The lab reports an IgE level in kU/L and compares it with its reference range. A level above that range means you are sensitized.

Questions

Common questions.

Anything else, our care team answers by phone, text, or email.

It can. Milk proteins from goats, sheep, and cows are similar, so sensitization to one can come with sensitization to the others. This test measures IgE to sheep milk specifically.

An allergist reads it with your cow’s milk result and your history. Decisions about which milk to use belong with your allergist, not with this result alone.

No. Sensitization means your body has made IgE to sheep milk. An allergy means that exposure causes symptoms. Many people are sensitized without having symptoms, so a positive result alone does not mean you are allergic.

A negative result does not clear an allergy either. An allergist or other healthcare provider reads your result with what happens when you are exposed.

Get emergency care. If you have trouble breathing, swelling of the face or throat, or you feel faint or pass out after eating any food, call 911 right away. If you have a prescribed epinephrine auto-⁠injector, use it as directed. This blood test is not for urgent reactions.

After a serious reaction, an allergist can talk with you about what happened and which tests make sense.
