Practical guides on continuous glucose monitoring, remote patient monitoring and billing, and metabolic health — for the clinicians who deliver care and the people who want to understand their own.
Tools & calculators
Convert HbA1c to estimated average glucose (eAG), and CGM mean glucose to GMI, with the standard clinical formulas.

What continuous glucose monitoring is, how it works, what the metrics mean, and how to read your data — the full library, one place to start.
Start here →The sensor, the interstitial fluid, the lag behind blood glucose, and the warm-up period — in plain English.
Read the guide →What MARD means, why accuracy varies, and when a finger-stick still matters.
Read the guide →What each measures, trends vs single points, and where finger-sticks are still needed.
Read the guide →Real-time vs scanning, factory-calibrated vs not, skin-worn vs implantable — a neutral overview.
Read the guide →The AGP report, the median line, the overnight window, and the patterns worth looking for.
Read the guide →How the standardized one-page report overlays days of data into a single picture.
Read the guide →What a sensor can and can't tell someone without diabetes — educational, not diagnostic.
Read the guide →Prescription vs OTC, wear time, alerts, phone compatibility, and cost — what to weigh.

The abnormal glucose patterns that show up years before diabetes — what they mean and how they're spotted.
Read the guide →What each measure actually tells you, when each is used, and why the two can disagree.
Read the guide →Why an average isn't enough, and the consensus targets that describe the shape of control.
Read the guide →What the Glucose Management Indicator means, and why it can differ from a lab HbA1c.
Read the guide →What variability and coefficient of variation mean, and how a CGM reveals the swings.
Read the guide →Why glucose climbs before you wake, and how a CGM trace tells it apart from a rebound.
Read the guide →The after-meal glucose drop — symptoms, what it may mean, and when to seek evaluation.
Read the guide →What a CGM can and can't show before diabetes, and where standard tests still lead.
Read the guide →What the research does and doesn't support, framed carefully as decision support.
Read the guide →Why CGM is moving beyond insulin users, the evidence, and how a primary-care team can start.
