A serum/clot separation surface determination apparatus includes a test tube formed of a non-magnetic material containing a blood sample which is separated into a serum and a clot by a silicon separating medium, a detection coil fitted on an outer surface of the test tube, a measurement signal supply unit which supplies a measurement signal having a given frequency to the detection coil, a drive control unit which variably controls a relative position between the detection coil and the test tube in a longitudinal direction of the test tube by moving at least one of the detection coil and the test tube, a signal level detector which detects a level of the measurement signal that varies with the relative position, and a determination unit which determines a position of a sample separation surface obtained by the silicon separating medium, based on the level of the detected measurement signal.
