[A simple and quick method for measuring low blood-glucose concentrations (author's transl)]

Area of Science:

• Clinical Chemistry
• Biomedical Diagnostics
• Analytical Chemistry

Background:

• Accurate glucose monitoring is crucial for diabetes management.
• Existing methods may have limitations in certain clinical settings.
• The Reflotest-Hypoglycemie offers a potential alternative for glucose quantification.

Purpose of the Study:

• To evaluate the performance of the Reflotest-Hypoglycemie method for glucose measurement.
• To compare the Reflotest-Hypoglycemie with a standard hexokinase-based method.
• To assess the reliability and accuracy of the Reflotest-Hypoglycemie across different laboratories and sample types.

Main Methods:

• Analyzed 141 serum and 119 capillary blood samples.
• Compared Reflotest-Hypoglycemie results against the hexokinase-glucose-6-phosphate dehydrogenase reference method.
• Assessed inter-laboratory variability using samples from six different labs.
• Investigated the impact of endogenous bilirubin, uric acid, and hematocrit on test results.

Main Results:

• The Reflotest-Hypoglycemie demonstrated good agreement with the reference hexokinase-glucose-6-phosphate dehydrogenase method.
• Inter-laboratory comparisons confirmed the test's accuracy and consistency.
• Glucose measurements were not significantly affected by variations in bilirubin, uric acid, or hematocrit levels.

Conclusions:

• The Reflotest-Hypoglycemie is a suitable method for quantitative glucose measurements.
• The method's robustness against common interfering substances enhances its clinical utility.
• Reflotest-Hypoglycemie offers a reliable and accurate option for blood glucose monitoring.
