In accord with one aspect, a microfluidic coagulation assessment device defining a plurality of microchannels is provided, wherein a blood sample is driven through the microchannels at a substantially constant flow rate and a controller is configured to, in combination with a timer and a pressure sensing device, determine a first pressure value (or flow value) at an initiation of flow, a first time (Tpg) at which a second pressure value is about twice the determined first pressure value, and a second time (Tpf) at which a third pressure value is about (1+e) times the determined first pressure value and establish a subject coagulation model predictive of channel occlusion therefrom. In another aspect, the blood sample is driven through the microchannels at a substantially constant pressure and a controller is configured to, in combination with a timer and a flow sensing device make the determination based on flow rate.
