Region 10 IgE Allergy Blood Panel

What this test measures

Texas and Oklahoma sit at a crossroads of allergen zones. Mountain cedar sheds abundant winter pollen, oak and pecan trees pollinate in spring, warm-season grasses such as Bermuda and Bahia release pollen through summer, and ragweed and other weeds extend the season into autumn. Mold spores can remain high in humid periods, and indoor allergens like dust mite are common year round.

The panel measures allergen-specific IgE for 26 regionally selected targets from one blood sample. Reported allergens may include winter tree pollens, spring trees, warm-season grass pollens, weeds such as ragweed and pigweed, molds including Alternaria and Cladosporium, and indoor allergens. Each target is reported with its own quantitative level and graded class.

Residents of Texas and Oklahoma who experience seasonal or persistent nasal, eye, or airway symptoms may find this panel useful, as may people who have recently moved to the area. It can also help narrow down which allergens to follow up on with a clinician. Results are interpreted with the person's symptoms and environment.

• Regional tree pollen IgE (cedar, oak, pecan, and related species as included)
• Warm-season grass pollen IgE (Bermuda, Bahia, and related grasses as included)
• Weed pollen IgE (ragweed, pigweed, and related weeds as included)
• Mold spore IgE (Alternaria, Cladosporium, and related molds as included)
• Dust mite IgE when included
• Cat and dog dander IgE when included
• Allergen-specific IgE class for each of the 26 panel allergens

Why people order this test

• Investigate year-round or multi-season allergy symptoms in the southern plains
• Check winter cedar and spring tree pollen sensitization together
• Screen warm-season grass and weed pollens in one sample
• Assess whether mold and indoor allergens contribute to symptoms
• Guide which specific allergens to discuss with a clinician

How to prepare

No fasting is needed, and the test can be done at any time of year. Follow the lab's routine instructions for the blood draw.

Understanding your results

Results generally return within one to three business days. The report lists each allergen separately, allowing patterns such as winter tree pollen sensitivity to stand out. Positive results reflect sensitization and are interpreted by a qualified healthcare provider alongside symptoms.
