Recalls for Electrode, Ion Specific, Sodium

Siemens Healthcare Diagnostics Inc. has confirmed that a negative sodium bias may exist in some epoc test card lots. All other analytes are performing as intended. The observed average bias for sodium was -4.4 mmol/L. The maximum bias observed was -14 mmol/L, which occurred at a higher sodium concentration around 150 mmol/L. No positive bias has been observed. Quality Control (QC) fluid may or may not detect the issue depending on the bias magnitude and the frequency of QC testing.

There are potential drug interferences from Perhexiline Maleate or Atomoxetine Hydrochloride that may cause falsely elevated sodium results reported on the RAPIDPoint 500 and RAPIDPoint 500e Blood Gas Systems. The erroneous sodium levels with positive bias may lead to unrecognized hyponatremia and/or the inappropriate treatment of hypernatremia may lead to iatrogenic hyponatremia, resulted in a delay in patient diagnosis and optimal patient management.

Potential risk of reporting erroneous creatinine patient results associated with the initial start-up of a new BUN/Creatinine Sensor Cartridge. The potential risk is within the first 2-4 hours after cartridge installation that may not be identified by traditional Quality Control practices.

Some lots ending in "17", "18", "19", or higher may have cuvette defects allowing water from the water bath to contaminate the interior of the cuvette, which may falsely elevate or depress sample results.

The I-STAT BLUE CHEM8+ and CG4+ cartridges are not FDA cleared and do not have CLIA waived status. CLIA recognizes two types of laboratory tests: waived and non-waived. Different CLIA standards apply to waived and non-waived tests as well as the facilities that perform these types of tests. The i-STAT CHEM8+ cartridge contains nine measured assays (sodium, potassium, chloride, blood urea nitrogen (BUN), ionized calcium, TCO2, glucose, creatinine and hematocrit) and is categorized as a CLIA waived test for venous whole blood samples, meaning this cartridge could be used in a facility with a CLIA Certificate of Waiver as a waived test.

Siemens Healthcare Diagnostics has confirmed an issue with ADVIA Chemistry XPT software version 1.0.2. The system may cause samples to remain in an Inprocess state. Test results on a sample that is held Inprocess will not transmit to the LIS. Manual intervention is necessary to complete the processing of the samples that are held Inprocess.

Ortho Clinical Diagnostics has recalled VITROS Chemistry Products Na+ Slides and the Calibrator Kit 2 due to false positive serum and plasma sample results.

RADIOMETER become aware that if the ABL90 FLEX is tilted, this may potentially cause a negative bias on sodium (Na+) results.

HORIBA Medical is informing all ABX PENTRA 400 Analyzer with I.S.E. Module customers that there are no Linearity Limit Flags for the I.S.E. assays currently programmed into the ABX PENTRA 400 Analyzer software. All other assays run on this analyzer do have Linearity Limit Flags to alert the user to values that fall below or above the validated linearity range for each assay.

This recall was initiated because Beckman Coulter has confirmed that for User-Defined Chemistries (UDRs), the polychrome correction is not automatically updated when wavelengths are modified.

i-STAT CHEM 8+ cartridge may generate false results for sodium, chloride and hematocrit.

The field action was initiated after the firm confirmed reports of premature failure of the waste pump tubing in the Access and Access 2 Immunoassay Systems. Premature failure of the waste pump tubing may negatively affect precision.

Incorrect results/stability failure; Actual device stability studies show sodium and chloride sensors age differently than anticipated when stored at the high end of labeled storage, therefore subsequent measurements give results outside the allowed error allowance before the 6 month expiration date shown on the device.

Low QC recovery observed on carbamazepine (CARB) results immediately following a Gentamicin (GENT) assay or a Digoxin (DIG) assay. When GENT or DIG precedes CARB, the CARB test result is artificially low (as much as -25%). PHNY was determined to also exhibit a similar carryover effect on CARB. All others were found not to produce the same reagent probe-based carryover effect.

ISE module may produce discrepant, unflagged results for Sodium, Potassium or Chloride when the respective electrode is left unplugged after replacement, washing or maintenance activities. The calibration and 2-level QC will fail if the electrode is left unplugged. The IFU states to calibrate the ISEs after replacement and to run two levels of controls before running patient samples.

(1)Software (SW) versions V1.25.1 and lower may result in TDef (Test Definition) Parameters for Open Channel Assays reverting to Default Value would shift test results by the magnitude of the implemented Assay Correlation factor; (2) On Board Stability (OBS) Not Updating with Manual Change for Open Channel Assays may continue to use the reagent past its expiration date leading to potential erroneous patient sample results

Multiple issues in Software v1.23.2 and lower-may lead to the reporting of discrepant patient results

On the Atellica CH 930 Analyzer, when scanning barcodes at the module console for Integrated Multisensor Technology (IMT) system fluids (Standard A (Std A) and Standard B (Std B)) for Sodium (Na), Potassium (K), and Chloride (Cl), the system will translate the decimal point separators to commas. This will result in invalid concentration values for the fluids, therefore the system will utilize default nominal values instead of lot specific IMT fluid concentration values for calculation of the calibrations and results for the Na, K, and Cl methods.

The gas spring on the front and rear protective cover may fail. There is a low risk of injury to the user resulting from failure of the gas spring. Injury may include impact to the arms, hands or fingers.

Imprecision in the affected lot may produce negatively or positively biased patient sample and quality control fluid results.

There is a potential for biased results to be generated over the 10 day on-analyzer storage limit when using VITROS Na+ Slide cartridges warmed at room temperature and loaded onto the analyzer after using the minimum warm up requirements stated in the IFU. If Quality Control (QC) results are within acceptable limits, reported results are acceptable and were not affected by this issue.

There were multiple issues identified in the system software which required an update.

When more than one immunoassay analyzer is connected to a single solution system, reporting and conversion factors may not be applied to all analyzers

Editing an assay Test Definition and switching to another assay s Test Definition screen without saving the changes using the save button on the screen, may corrupt the settings of the assay s test definition, and Auto-Rerun or Auto-Dilution results may generate a result of Zero (0) for quantitative assays or Negative for qualitative assays if a well of the reagent pack is not calibrated.

Photometer Lamp May Reach Saturation Without Flagging Results, may generate erroneously elevated or depressed patient results

ADVIA Chemistry System and Software Versions (V1.4 SMN 11314625 and V1.4 China SMN 11316885) may not be aligned with customer expectations for the current default mixer failure detection setting of 2; an erroneously elevated or depressed patient result to be reported without alert on the test result

Valves used on the Atellica CH 930, Atellica IM 1300 and Atellica IM 1600 analyzers may develop a malfunction due to a manufacturing defect and may result in the valve wearing and leaking over time. The leaking is a risk in valves subject to high pressure or high wear and may impact the result accuracy of any assay.
