The Region 11 Allergies test is a blood test that looks for antibodies your immune system may make against common allergens found in the south-central United States, including Texas, Louisiana, Arkansas, Oklahoma, and New Mexico. It is usually ordered when someone has ongoing allergy symptoms and a clinician wants to identify possible triggers.

What it measures

  • Total IgE — A general measure of allergy-related immune activity.
  • Specific IgE to grasses — Antibodies linked to grass pollen reactions.
  • Specific IgE to trees — Antibodies linked to tree pollen reactions.
  • Specific IgE to weeds — Antibodies linked to weed pollen reactions.
  • Specific IgE to molds — Antibodies linked to mold spore reactions.
  • Specific IgE to dust mites — Antibodies linked to indoor dust mite reactions.

Who it is for

A primary care clinician, allergist, or immunologist typically orders this test. It may be requested for adults or children with persistent sneezing, nasal congestion, itchy eyes, or asthma-like symptoms.

Preparation

No fasting is required. Tell your clinician about allergy medications, since some may affect results; timing of the blood draw is not otherwise restricted.

Results and what they mean

Results are reported as antibody levels, often grouped by allergen, and may include a reference range. A clinician interprets these values alongside your symptoms and history, because a positive result does not always mean you have an allergy. This is general information only and not medical advice; discuss your results with a qualified clinician.

Do I need to stop my allergy medicine?

Ask your clinician. Some medicines can affect results, so they may adjust your plan before testing.

Can this test diagnose an allergy?

It supports a diagnosis, but a clinician must combine results with your symptoms and exam.
