Exposure biomarkers and risk from gluing and heating of polyurethane: a cross sectional study of respiratory symptoms

Table 6

Sensitivity and specificity (%) of classification of exposure to sprayed or heated glue for work related symptoms of the airways, and of metabolites of 4,4′-diphenylmethane diisocyanate (MDI; P-MDX) in plasma and specific IgG against MDI for exposure and work related symptoms of the airways (S-IgG-MDI)in 152 workers and 14 clerks, potentially exposed to sprayed or heated polyurethane glue

  • ↵6-150 LM=limit of measurement; the estimation of sensitivity and specificity refers to values above this limit.

  • ↵6-151 The estimation refers to values above the median.

  • ↵6-152 The estimation refers to positive S-IgG-MDI values.
