CHEMISTRY ANALYZER AU5800, REF: B96697, B96698, B23279, B23280, B23281

A delay in results may occur. When clinical chemistry analyzer calibration monitor with PC installed with Microsoft SQL Server 2022 Express is open beyond15 minutes may lead to: Reagent Blank and calibration databases not opening errors: CAL History DB Open Error.., RB History DB Open Error..; system will stop analyzing, firm service must visit to apply software solution; may lead to delay in diagnosis and/or patient treatment

Sample probe sucks a sample dispensed into a tube or cup and discharges the appropriate amount into a cuvette. Lot 178713114 - 179433670

Sample probes with defective probe tips, when used with clinical chemistry analyzers, may lead to a lower concentration being dispensed, which may not be detectable by QC checks, which could lead to the reporting of false low test results (Max 34% error at 1.0 microliters and 7% error at 1.6 microliters sample dispensing volume), which may lead to delayed recognition and treatment.

Sample probe sucks a sample dispensed into a tube or cup and discharges the appropriate amount into a cuvette. Lot 178713114 - 179433670

A manufacturing defect in the sample probe (S probe). The corners of the tip of the defective S probe are rounded and chamfered, which can prevent the proper formation of the "air layer" required for normal dispensing. The air layer is the air space that separates the cleaning water filled in the probe from the sample sucked into the probe. Maintaining this air space prevents the cleaning water and the sample from mixing. In the defective S probe, the "air layer" was not properly formed, causing the cleaning water and the sample to mix diluting the sample. As a result, the sample mixture dispensed into the cuvette has a lower concentration than the original sample, and the analyte concentration measured is lower than expected results.

DxC 500 AU Clinical Chemistry Analyzer, REF C63520 is an automated chemistry analyzer that measures analytes in samples, in combination with appropriate reagents, calibrators, quality control (QC)

Due to a software issues, after the instrument processes 250 racks cumulatively, any subsequent racks with samples requiring rerun/reflex will be held in the Sample Handler's Buffer area and and error code "9000" will be reported. This issue may cause a delay of results.

DxC 500 AU Clinical Chemistry Analyzer, REF C63520 is an automated chemistry analyzer that measures analytes in samples, in combination with appropriate reagents, calibrators, quality control (QC)

There are two software bug issues with the analyzer. Issue 1: When a dedicated rack is reserved for calibration, after a calibration test has been placed and completed, the same rack may be used to place both a patient order and a calibration order. When a patient sample and a non-barcoded calibrator tube is processed on the rack, the calibration result will be reported as a patient result. Issue 2: calibration with expired calibrator. They both may cause erroneous patient results, but the probability of serious adverse health consequences or death is unlikely.
