1. A clinical diagnostic analyzer system with validation of a replicate measurement of a patient sample using post-measurement error detection, the clinical diagnostic analyzer system comprising:

  • a patient sample input device for receiving the patient sample; and

    a processor for executing instructions to perform the steps of an analysis method using the clinical diagnostic analyzer system, the analysis method comprising;

    performing the replicate measurement of the patient sample with instructions of a required assay;

    receiving measurement messages as a result of performing the replicate measurement;

    receiving device status messages indicating status of the clinical diagnostic analyzer system;

    generating a fingerprint of expected events to be tested for the replicate measurement from at least a configuration information and a protocol information thereof, wherein the protocol information contains details for the assay required by the replicate measurement;

    validating the replicate measurement of the patient sample by comparing the received measurement and device status messages with the fingerprint to facilitate error detection, the validating step comprising the step of matching the received measurement messages and the received device status messages with the fingerprint of the expected events to determine a success or a failure of the replicate measurement; and

    releasing the replicate measurement upon the success of the replicate measurement and preventing release of the replicate measurement upon the failure of the replicate measurement.
