Hypothesis
The use of immobilized enzymes can enhance the analytical and economic efficiency of glucose testing methods.
Conclusion
The modified glucose testing method using immobilized enzymes shows improved stability and reduced reagent costs compared to the original method.
Supporting Evidence
- The modified method allows for a production rate of 100 determinations per hour.
- The stability of the buffered coenzyme reagent is one month at room temperature.
- The average deviation between the modified method and the glucose DH method is +5 for whole blood and +3 for urine.
- The annual cost of the modified method is estimated to be $3550.
Takeaway
This study found a better way to test glucose using special enzymes that can be reused, which saves money and time.
Methodology
The study involved modifying an existing glucose testing method by using immobilized enzymes and optimizing various parameters such as sample preparation and reagent consumption.
Limitations
The method's sensitivity to pH changes during cleaning may affect its reliability.
