A result of 0.10 or more falls in the next class: Labcorp calls 0.10 to 0.31 class 0/I (equivocal or low), and ARUP calls 0.10 to 0.34 'clinical relevance undetermined' and says it is meant for specialist use. Thermo Fisher, which makes the ImmunoCAP assay, says results above 0.1 kUA/L are indicative of sensitization, and the older cutoff of 0.35 kU/L is still used in many studies, including the US NHANES survey. A result above the range shows sensitization, not necessarily an allergy.
