The clinical relevance of allergen results of 0.10 - 0.34 kU/L are undetermined and intended for specialist use. Allergens denoted with a ** include results using one or more analyte specific reagents. In those cases, the test was developed and its analytical performance characteristics have been determined by Quest Diagnostics. It has not been cleared or approved by the U.S. Food and Drug Administration. The FDA has determined that such clearance or approval is not necessary. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes.
