By either comparing values or using independently the value of either the large non-whole parathyroid hormone peptide fragment, the whole parathyroid hormone, or the combination of these values, one is able to differentiate parathyroid and bone related disease states, as well as differentiate such states from normal states.

Abstract: A method, data processing system, and computer program product are provided for performing time-based symbolic simulation. A delay-aware representation of a circuit is created that includes a plurality of circuit nodes. The data-aware representation is simulated. In particular, the simulator simulates transitions from a first set of circuit nodes to a second set of circuit nodes selected from the plurality of circuit nodes, the simulating based on executing a first set of simulation events. A second set of simulation events is then generated in response to executing the first set of simulation events. During the simulation, a time is computed for each of the transitions. An an event scheduling diagram is constructed during simulation. The event scheduling diagram depicts the transitions and the times of the transitions.
