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.

Abstract
Disclosed is a clinical diagnostic analyzer employing a redundant error detection capability to further examine the internal message traffic for possible errors or questionable results by comparing the actual parameters against a fingerprint generated for each assay using an assay database and a configuration file. This testing does not rely on inputs from the software module being tested, and hence is an independent test. Further, a testing mechanism is provided to test the Redundant Error Detection (“RED”) capability itself.

10. A method for validation by a clinical diagnostic analyzer system of a replicate measurement of a patient sample using post-measurement error detection, the method comprising:
-
receiving a preview replicate command for a replicate measurement; allocating resources for redundant error checking for the replicate measurement; generating a fingerprint of required events for the replicate measurement using at least a configuration information and an protocol information, wherein the fingerprint has fewer events than events performed in accordance with the protocol information for the replicate; comparing measurement messages corresponding to carrying out the replicate measurement, and device status messages indicating status of the clinical diagnostic analyzer system, with the fingerprint, the comparing step comprising the step of matching the measurement messages and the device status messages with the generated fingerprint to determine a success or a failure of the replicate measurement; sending a result of the comparison to facilitate 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; and logging conditions corresponding to the replicate measurement. - View Dependent Claims (11, 12, 13)
