    Abstract: An apparatus for determining the capacity of a blood sample to clot, the apparatus having a body with a cavity thereon to receive the blood sample, a displacement member movably received on the body and movable from a first position to a second position, a spring element for imparting a retaining force against movement of the displacement member from the first position, and a discrete indicator for generating a signal when the displacement member is moved to the second position. The coagulation and contraction of the blood sample as it clots adheres to and moves the displacement member from the first position towards the second position against the retaining force of the spring element. The indicator may include a mechanical switch, an exothermic chemical switch, a chemiluminescent chemical switch, a segmented optical pathway, an electrical switch, a field effect transistor switch or a Hall effect magnetic switch.
