Sorrel allergy is a pollen allergy caused by sensitivity to sorrel plants, particularly sheep sorrel. It occurs when the immune system produces IgE antibodies in response to sorrel pollen proteins, triggering allergic symptoms during pollen season. The Respiratory Allergy Profile Region IX is the most important test for diagnosis because it measures specific IgE antibodies to sheep sorrel.
Sorrel allergy is caused by an immune system overreaction to proteins found in sorrel pollen, particularly from sheep sorrel plants. When you inhale sorrel pollen, your immune system mistakenly identifies these harmless proteins as dangerous invaders and produces IgE antibodies to fight them. This immune response triggers the release of histamine and other chemicals, leading to allergic symptoms like sneezing, runny nose, itchy eyes, and respiratory discomfort during pollen season, typically in spring and summer months.
The Respiratory Allergy Profile Region IX is the most important test for sorrel allergy because it specifically measures IgE antibodies to sheep sorrel along with other regional allergens common in the Great Plains. This comprehensive blood test detects the presence and levels of specific IgE antibodies your immune system produces in response to sorrel pollen proteins. Higher antibody levels indicate a stronger allergic sensitivity and help confirm that your symptoms are specifically triggered by sorrel exposure rather than other environmental allergens. This targeted testing allows your healthcare provider to develop an appropriate treatment plan, including allergen avoidance strategies and medications.
You should get tested if you experience seasonal allergy symptoms like sneezing, runny nose, itchy or watery eyes, nasal congestion, or breathing difficulties that consistently occur during spring or summer months when sorrel plants release pollen. Testing is particularly important if you live in or frequently visit areas where sheep sorrel grows abundantly, such as grasslands and fields in the Great Plains states. You should also consider testing if over-the-counter allergy medications are not effectively controlling your symptoms, or if you want to identify your specific allergen triggers to better manage your condition and avoid unnecessary exposure.
What this means
Your IgE antibodies to common ragweed are elevated, indicating a positive sensitization. This suggests ragweed pollen is likely a trigger for your late summer and fall allergy symptoms like sneezing, runny nose, and itchy eyes. Understanding this trigger allows you to take preventive measures during ragweed season, typically August through October in your region.
Recommended actions
Monitor pollen counts and stay indoors when ragweed levels are high, especially on dry, windy days
Keep windows closed during ragweed season and use air conditioning with clean filters
Shower and change clothes after spending time outdoors to remove pollen
Consider starting antihistamines before ragweed season begins and discuss immunotherapy options with your doctor
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
