Allergen, Grass, Cultivated Barley Pollen IgE
Also known as: BARLEY POL
Use
The test measures the amount of immunoglobulin E (IgE) specific to cultivated barley pollen in the blood. IgE is an antibody associated with allergic reactions. Its levels can provide insights into the likelihood of an individual having an allergic response to specific allergens such as barley pollen. This makes it useful for diagnosing and managing allergies, allowing healthcare providers to tailor avoidance and treatment strategies. Results need to be interpreted in conjunction with the clinical history and other allergy tests, as IgE levels alone might not fully represent the patient’s allergic status or predict reactions.
Special Instructions
Not provided.
Limitations
The clinical relevance of IgE levels from 0.10 to 0.34 kU/L is undetermined and should be used with specialist guidance. While the test reflects concentrations of allergen-specific IgE, these may not correspond to clinical responses or skin test results. Negative results do not eliminate the possibility of an allergy or even anaphylaxis. It's crucial to correlate laboratory results with clinical history and in vivo reactivity to the specific allergen.
