  • Title: The chemistry of commercial continuous glucose monitors.
    Author: McGarraugh G.
    Journal: Diabetes Technol Ther; 2009 Jun; 11 Suppl 1():S17-24. PubMed ID: 19469674.
    Abstract:
    The analytical methodologies of the continuous glucose monitors (CGMs) commercialized to date are described. The devices include two noninvasive products: the GlucoWatch (Cygnus, Redwood City, CA) G2 Biographer uses iontophoresis to obtain a sample and electrochemistry for glucose detection, and PENDRA (Pendragon Medical Ltd., Zurich, Switzerland) utilizes impedance spectroscopy. Three minimally invasive systems employ subcutaneous amperometric sensors-Guardian REAL-Time (Medtronic MiniMed, Sylmar, CA), DexCom STS-7 (DexCom, San Diego, CA), and FreeStyle Navigator (Abbott Diabetes Care, Alameda, CA). The GlucoDay (A. Menarini I.F.R. S.r.l., Florence, Italy) collects a sample with a minimally invasive microdialysis fiber and measures the glucose electrochemically.
