ABSTRACT:
Apparatus for determining bleeding time includes a cutting assembly and a member for providing a compensation factor as a function of temperature of the subject. The cutting assembly provides an incision of predetermined dimensions for external bleeding therethrough. The compensation member measures temperature of the subject throughout the period of external bleeding and provides a compensation factor as a function of sensed temperature. The multiplicative product of measured time length of external bleeding and the compensation factor provide a normalized bleeding time of the subject.
