[Automatic assay of blood sugar by Trinder's method]

Area of Science:

• Biochemistry
• Analytical Chemistry
• Clinical Diagnostics

Background:

• Accurate blood glucose measurement is critical for diabetes management.
• Existing methods may have limitations in accuracy or interference.
• Automation can improve efficiency and consistency in glucose testing.

Purpose of the Study:

• To adapt and validate an automated method for true blood glucose determination.
• To assess the accuracy, contamination, and interference profile of the new method.
• To compare the results with established Hexokinase and Beckman Glucose Analyzer methods.

Main Methods:

• Adaptation of the glucose-oxidase peroxidase system to a single-channel AutoAnalyzer.
• Direct coupling of enzymatic action with an oxygen acceptor chromogen.
• Validation through accuracy, contamination, and interference testing.

Main Results:

• The automated method demonstrated validity for accuracy and absence of interferences.
• A thorough examination revealed a strong correlation between the automated method and Hexokinase/Beckman Glucose Analyzer results.
• The method reliably quantifies true blood glucose.

Conclusions:

• The adapted automated method provides a valid and accurate means for determining true blood glucose.
• This technique offers a reliable alternative for clinical glucose monitoring.
• The strong correlation supports its clinical utility in comparison to established methods.
