Blood Glucose Monitoring

Continuous measurement and tracking of blood glucose levels, essential for diabetes management and metabolic health optimization. Continuous glucose monitors (CGMs) provide readings every 1-5 minutes, revealing glucose patterns invisible to periodic fingerstick testing—including nocturnal hypoglycemia, postprandial spikes, and dawn phenomenon. Users can set customizable high/low alerts to prevent dangerous glucose excursions. Time-in-range metrics (typically 70-180 mg/dL for diabetics) provide more actionable feedback than single-point measurements or HbA1c alone. For people with diabetes, CGM use is associated with improved glycemic control (0.5-1% HbA1c reduction) and reduced hypoglycemia. Emerging applications for non-diabetics include metabolic health optimization, understanding individual food responses, and athletic performance fueling. CGM devices are FDA-regulated Class II medical devices; accuracy is measured by Mean Absolute Relative Difference (MARD), with current systems achieving 9-11%.
