Diagnostics and laboratory monitoring of gestational diabetes mellitus in Russia. The authors' view of the problem and controversial issues

Despite the existence of the Russian Consensus on gestational diabetes mellitus (GDM) since 2012 in the Russian Federation, its implementation into clinical practice has been slow, partially because its creation took place without the participation of laboratory services. In this review issues of preanalytical and analytical considerations of such laboratory tests as the blood glucose test, oral glucose tolerance test (OGTT), glycosylated hemoglobin test are discussed. If the presence of prandial hyperglycemia from 5.1 to 5.6 mmol/l is identified, testing should be repeated to confirm the diagnosis of GDM. OGTT must be performed using venous blood samples with fluoride in a specialized laboratory with fast transportation of samples.
