Latex Medical Gloves: Time for a Reappraisal Int Arch Allergy Immunol 2011;156:234–246 - DOI:10.1159/000323892 Fig. 1. Relationship between the results from the four-NRL allergen sum test (µg/g) and human IgE-ELISA inhibition test (AU/ml) in 208 medical gloves. In the human IgE-based assay values below 1 AU/ml are considered as ‘very low’ allergenic, values from 1.0 to 9.9 AU/ml as ‘low allergenic’, values from 10.0 to 99 AU/ml as ‘moderately allergenic’, >100 AU/ml as ‘highly allergenic’. The vertical dotted lines denote limits for the very low (1 AU/ml) and low (10 AU/ml) limits. The horizontal dotted line marks the 0.15 µg/g limit in the four-allergen sum test. AU = Allergen unit.
