Enzyme Chemistries: GOx vs. GDH

Introduction

Diabetic test strips use enzymes to measure blood glucose levels. Two dominant enzymes are Glucose Oxidase (GOx) and Glucose Dehydrogenase (GDH).

GOx is the traditional choice, offering high specificity and accuracy. GDH provides faster response times and higher sensitivity.

Specificity: GOx wins on specificity, reducing interference from other substances.
Response Time: GDH reacts faster, giving quicker results.
Stability: GOx is more stable, with a longer shelf life.
