Type 1 diabetes in adults: Antibody affinity is decisive

[Northerner]

Patients with LADA -- a form of autoimmune type 1 diabetes in adulthood -- can be distinguished from patients with non-autoimmune type 2 diabetes by means of the antibody reaction affinity to the enzyme glutamic acid decarboxylase (GAD). Scientists have reported that high-affinity GAD antibodies are found in patients who produce only a little of their own insulin and who will require insulin therapy after only a relatively short time.
