Clinical Use

Use

Quantitative allergen‑specific IgE test to detect sensitization to carmine red dye. It is used for clinical purposes and should not be regarded as investigational. Results must be interpreted in the context of clinical and laboratory findings; high total IgE (>3000 IU/mL) may cause nonspecific binding and testing should be re‑evaluated once medical conditions are resolved.
