Continuous Glucose Monitors (CGM) offers 14 days of continuous blood sugar monitoring, but they require many parts for assembly, are expensive and sadly all parts are completely disposed of every time. GlucoStick revolutionizes diabetes tracking by retaining all the monitoring conveniences of CGMs, but reuses a sterilizable lancing stick where users merely twist on new, replacement lancets before each use, thereby reducing the amount of bio-hazardous waste generated and at a fraction of the cost of current CGM systems or even traditional glucose meters with test strips.
