title: [Pitfalls in the diagnosis and treatment optimization of type 2 diabetes].
abstract: The diagnosis of diabetes mellitus would appear a simple matter. However, potential pitfalls in clinical practice need to be avoided, and this requires knowledge and attention. An initially pathological oral glucose tolerance test should be repeated before establishing a final diagnosis, since such necessary preconditions as a 10 to 16 hours fast, or alcohol abstinence, are difficult to monitor in the clinical setting. Accurate glucose testing requires appropriate sample preparation and handling. Further pitfalls may be encountered during treatment: HbA1c assessment is associated with certain limitations and does not permit the estimation of glucose variations. To establish a differential diagnoses between type 1 (LADA) and type 2 diabetes in older patients GAD must be measured. New biochemical markers such as adiponectin and intact proinsulin may facilitate treatment decisions and monitoring in patients with type 2 diabetes.
