Reason

The slides failed to meet current claims for Limit of Blank (LoB), Limit of Detection (LoD) and Limit of Quantification (LoQ) for urine samples. The measuring range (15-300 mmol/L) for urine samples when tested with the Cl- slide is not affected. The current Cl- LoQ is 5 mmol/L and the LoQ determined by this investigation is 15 mmol/L.

Action

On 7/11/18, Important Product Correction Notification letters were distributed to customers. The letters instructed customers to perform the following actions: VITROS Cl- Slides and VITROS CREA Slides Instructions for Use will be updated to contain the revised information described in this letter; we will notify you upon availability. In the interim, retain a copy of this customer letter for your records.

Prior to the availability of the revised IFU, be aware that if a serum or plasma sample contains a Triglyceride concentration of 600 mg/dL or higher, the Chloride result may be positively biased by approximately 2.1 mmol/L. Follow your normal laboratory procedures as you would for other known assay interferences. Note: It is acceptable to continue using VITROS Cl- Slides. Upon availability, install the Calibration Diskette or ADD to implement the revised Measuring Range: For VITROS 4600, 5600 or 5,1 FS Systems: Install ADD DRV 5992 or above, Select All Assay Data option For VITROS 250/350 Systems: Install Calibration Diskette DRV 5992 or above Refer to the enclosure for additional instructions to update the Measuring Range. Update laboratory procedures and your Laboratory Information System (LIS), as necessary. Retain this letter until we send a notification to alert you when the revised IFUs are available.
