  epoc BGEM BUN Test Card [25pk]. Material Number: 10736515.

  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.

  RAPIDPOINT 500e Blood Gas System

  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.

  Atellica CH Reaction Ring Segment, SMN 11099326, UDI 00630414596143

  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.

  i-STAT CHEM8+ cartridges (blue), List No. 09P31-25. UDI (01) 00054749001910 - Product Usage: The i-STAT CHEM8+ cartridge may be used for the quantitative measurement of sodium, potassium, chloride, blood urea nitrogen (BUN), ionized calcium, TCO2, glucose, creatinine, and hematocrit in venous, arterial or capillary whole blood.

  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.

  ADVIA Chemistry XPT System, Siemens Material Number 10723034, Software Version 1.0.2, Siemens Material Number 11219493, IVD. The ADVIA XPT Chemistry System is an automated, clinical chemistry analyzer that runs tests on serum, plasma, urine, or cerebral spinal fluid in random access and batch modes at a throughput rate of both 1800 photometric tests per hour and 600 electrolyte (ISE) tests per hour.

  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.
