Rough Pigweed (w14) IgE
Also known as: ImmunoCAP®
Use
This test quantifies an individual’s IgE response to Rough Pigweed (W14), indicating sensitization. A positive result reflects the presence of allergen-specific IgE but does not confirm clinical allergy, which requires provider context and evaluation. Allergen-specific serum IgE testing is considered comparable to skin testing but is preferred in certain clinical situations.
Special Instructions
Not provided.
Limitations
A positive test indicates sensitization but many sensitized individuals remain asymptomatic. Diagnosis of allergy should only be made by a trained medical provider after thorough clinical evaluation. This test quantifies IgE response but does not confirm clinical allergy.
