US Market Leader Product Generations

The US diabetic test strip market is defined by the product generations of four major manufacturers: LifeScan, Roche, Ascensia, and Abbott.

Key Generational Trends:

1. Sensing Technology: A complete shift from Photometric (light-based) to Electrochemical (current-based) sensing, improving speed and accuracy.

2. Enzyme Chemistry: Evolution from Glucose Oxidase (GOX) to GDH-PQQ (which suffered from maltose interference/safety recalls) to the current standard of GDH-FAD and Mut. Q-GDH, which offer high specificity and oxygen independence.

3. User Experience: Reduction in blood sample volume (from 10µL down to 0.3µL), the elimination of manual coding ("No-Code" systems), and the introduction of "Second-Chance" sampling (Ascensia) to prevent wasted strips.

4. Accuracy: Modern generations (Contour Next, Accu-Chek Guide) utilize multi-pulse technology and complex algorithms to exceed FDA and ISO 15197:2013 accuracy standards.
