Abstract

Near-infrared quantitative analysis instruments (100) and methods non-invasively measure blood glucose by analyzing near-infrared energy following interactance with venous or arterial blood, or transmission through a blood containing body part (F). The instruments and methods are accurate and readily lend themselves to at-home testing by diabetics.
