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.

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.
