Whole blood flow dynamics determine the tissue oxygenation levels, hence carry life-critical value in several pathological conditions. Despite the long history of research on blood, the state-of-the-art lacks the ability to determine hemorheological properties of blood in a clinical setting. For this purpose, we developed a method to determine flow dynamics of blood using an optical-based detection technique. The system uses a novel pumping mechanism to induce in-vivo like flow conditions in a microfluidic channel that requires only a drop of whole blood for analysis. The measurement is completed in three minutes using a handheld analyzer device and can determine hemorheological properties, which can be linked to diseases related to red blood cell anomalies. Unlike the systems that are based on experimental single cell investigation or computational flow dynamics, these results open the avenue for blood studies that capture the cell-cell interactions as well as cell-medium interactions as in the circulatory system.
