Red Cedar (t57) IgE
Also known as: ImmunoCAP®, Juniperus virginiana, Red Cedar Juniper, Eastern Red Cedar
Use
This test quantifies an individual’s IgE response to red cedar. Allergen‑specific serum IgE testing is considered comparable to skin testing and may be preferred in certain clinical scenarios. A positive result indicates sensitization but does not necessarily imply clinical allergy; many sensitized individuals may remain asymptomatic. Diagnosis should be based on clinical evaluation by a qualified provider. Based on Quest Diagnostics Nichols Institute documentation.

Special Instructions
Not provided.
Limitations
A positive test result indicates sensitization only; it does not confirm clinical allergy. Many IgE‑sensitized individuals may not develop symptoms. Clinical correlation is essential. ([jdos.nicholsinstitute.com](https://jdos.nicholsinstitute.com/dos/questdemo/test/394835?utm_source=openai))
