Diagnosing Thistle Allergy
While symptoms may suggest a thistle allergy, definitive diagnosis requires blood testing that can detect specific antibodies (IgE) produced in response to thistle pollen exposure. This testing helps distinguish thistle sensitivity from other environmental allergies and guides appropriate treatment strategies.
Understanding Your Results
The test measures specific IgE antibodies in your blood that react to thistle pollen. Higher levels indicate a stronger allergic response. Results help healthcare providers develop personalized treatment plans, which may include antihistamines, nasal corticosteroids, or immunotherapy.
