Abstract
Methods and devices are provided for carrying out activated partial thromboplastin time (APTT) analysis on a whole blood sample to which no anticoagulant has been added by applying the sample to a capillary track contained in a housing, wherein the capillary track comprises sample entry and venting ports, at least one capillary track connecting the entry and venting ports, and reagents capable of initiating an APTT analysis, wherein clotting time is measured by the cessation of blood flow in the capillary track.
