REDUNDANT ERROR DETECTION IN A CLINICAL DIAGNOSTIC ANALYZER

摘要

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.

主权项

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 messages as a result of performing the replicate measurement;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; andvalidating the replicate measurement of the patient sample by comparing the received messages with the fingerprint to facilitate error detection.
