Abstract

A device (10) and method for analyzing blood coagulation in a blood sample. The device (10) includes a housing (12) having an analytical membrane (14) partially enclosed in a housing. The analytical membrane (14) includes a porous hydrophilic sample portion (34), a porous hydrophilic analytical portion (36), and a porous hydrophilic wicking portion (38). The porosity of the analytical portion (36) differs from the porosity of the sample portion (34). The method utilizes the device to analyze blood coagulation in a whole blood sample from the distance travelled by the red blood cell leading edge (50) in a predetermined period of time.
