The aim: to analyse the peculiarities of laboratory indices of patients with type 1 and 2 diabetes mellitus (DM).
Material and Methods. 452 patients with I and II type DM were examined and hospitalized at Klaipėda University Hospital. Glucose concentration, glycosylated heamoglobin (HbAlc), DM, and 77.2 % - type 2. According to the statistically significant positive relationship, type 1 is more common among younger, and type 2 DM is more common among older patients. The statistically significant positive relationship between DM and the patient’s sex was determined: statistically, type 1 DM is more significant for men, and type 2 - for women. Having evaluated the biochemical blood indices of patients with type 1 DM, a statistically significant negative relationship between the age and HBAic in patients with type 1 DM was estimated. Statistically significant positive rel ationship was found between the age of patients with type 1 DM and creatinine peptide concentrations and between glucose concentration and HBAic. Statistically significant positive relationship between creatinine concentration and the patients’ age with type 2 DM were determined. The re la tion ships be tween C-pep tide and creatinine and between C-peptide and glucose of the patients in type 2 DM group were also statistically significant and positive.
Conclusions. The blood glucose concentration test is the earliest and the most informative index for diagnosis of type 1 and 2 DM. Since the price of this research in comparison with the price of glycosylated heamoglobin concentration test is much lower, blood glucose concentration test is recommended as the most appropriate test for prevention of diabetes mellitus and its current control.
