Leucocyte migration test and hypersensitivity to glafenin.

The leucocyte migration test (LMT) was performed on 20 patients with an intolerance to glafenin--a non-narcotic analgesic drug. LMT was found to be positive in 50% of the subjects with intolerance, a highly significant percentage as compared with the control groups. HSA-glafenin was found to be the most appropriate method for presenting the antigen, but glafenin and its hydroxylated metabolites were only found to induce a migration inhibition in the subjects intolerant to glafenin.
