Performing Lab
Nettle (W20) IgE
Also known as: ImmunoCAP®
Clinical Use
Order TestUse
This test quantifies an individual’s IgE immunoglobulin E antibody response to nettle (W20) pollen. It aids in identifying sensitization to nettle allergy, though a positive result indicates sensitization—not necessarily clinical allergy. Diagnosis should be made by a trained provider taking into account clinical context and history.
Special Instructions
Not provided.
Limitations
A positive result indicates sensitization rather than clinical allergy—many IgE‑sensitized individuals do not experience symptoms. Clinical correlation is required for diagnosis. The test is not sufficient on its own to confirm allergy.
