Methodology:ImmunoCAP, fluorescent enzyme immunoassay
CPT Codes: 86003 x1
Turnaround Time:Specimens are sent to reference laboratory Mon-Sat; results are reported within 1-3 days.
Compliance:

This test uses a manufacturer labeled Analyte Specific Reagent (ASR) as the reagent providing the specificity of the assay. The test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.

Use:Allergen results of 0.10-0.34 kU/L are intended for specialist use as the clinical relevance is undetermined. Even though increasing ranges are reflective of increasing concentrations of allergen-specific IgE, these concentrations may not correlate with the degree of clinical response or skin testing results when challenged with a specific allergen. The correlation of allergy laboratory results with clinical history and in vivo reactivity to specific allergens is essential. A negative test may not rule out clinical allergy or even anaphylaxis.
