![]() ![]() Wilcoxon signed‐rank test showed no SatO2 difference between eyes and visits. Retinal oximeter Oxymap T1 (Oxymap ehf., Reykjavik, Iceland) was used to assess SatO2. The 4‐day study comprised two visits (Day l, Day 4) including 72 hr of continuous glucose monitoring (CGM) by iPro®2 Professional CGM (Medtronic, MiniMed, Inc., Northridge, CA, USA). Purpose of this prospective uncontrolled single‐centre pilot study was to find an association of retinal oxygen saturation (SatO2) with acid–base balance (ABB), carboxyhaemoglobin concentration, current plasma glucose concentration (PG), mean PG and PG variability over the last 72 hr, haemoglobin A1c (HbA1c), and other conditions.įorty‐one adults (17 men) with type 1 (N = 14) or type 2 (N = 27) diabetes mellitus, age 48.6 ± 13.5 years, diabetes duration 9 (0.1–36) years, BMI 29.4 ± 6.3 kg/m², and HbA1c 52 ± 12.7 mmol/mol completed the study. In addition to sustainable reviews of registered GSS also experienced data communication between health care professionals and GSS users should be considered. PG precision/variability in triplets of GSS Contour Plus One was demonstrated by SD 0.204☐.247 mmol/L.Ĭonclusions Required accuracy and precision of GSS Contour Plus One in clinical practice was confirmed and corresponds to the Requirements for blood-glucose monitoring systems for self-testing in managing diabetes mellitus ISO 15197 (2015). For vPG <5.55 mmol/L the required interval of ☐.83 mmol/L was reached in 51/51 (100%) cPG values measured on GSS Contour Plus One. ![]() Number of cPG values measured on Contour Plus One within the required interval ☑5% of vPG values was 200/207 (96.6%). Results Deviations of cPG measured on GSS Contour Plus One from vPG (in range ≥5.55 mmo/L) measured on Cobas Integra Analyser were -0.63☐.71 mmol/L (mean±SD). Precision was estimated using SD of average differences between individual cPG measurements. A total of 258 pairs of cPG vs vPG were compared using Wilcoxon signed rank test with Bonferroni correction. Software IBM SPSS Statistics for Windows, V. Following the cPG readings, venous blood was taken into a Grainer tube to measure venous plasma glucose (vPG) on Cobas Integra 400 analyzer using hexokinase. ![]() To obtain one triplet, one LOT of strips was used in three glucometers Contour Plus One. Triplets of cPG were investigated on GSS Contour Plus One (Ascensia, Switzerland) using glucosedehydrogenase strips. ![]() To support the feasibility of capillary plasma glucose (cPG) monitoring. Aims 1.To revise the accuracy and precision of glucometer-strips system (GSS) in a professional routine. ![]()
