Evaluation. In this study, the concept of "Drawing-PADs" is presented, which are paper-based microfluidic analytical devices that allow for the simple and intuitive evaluation of the urinary albumin (Alb) index. The Alb index is a clinically important parameter used for early detection of renal deficiencies related to diabetes and other diseases. To enable regular monitoring of the Alb index, a self-diagnosis method is highly desirable. The Drawing-PADs use the distance-based microfluidic PAD (μPAD) approach for simultaneous naked-eye detection of Alb and creatinine
