Due to calibration curves producing a higher activity than routinely expected and that there may be a decrease in separation between calibrator point 5 and calibrator point 6, which can be exacerbated with calibrator 6 activity reaches the optical ceiling of the SPA+ analyzer.

On 10/15/2021 (revised letter 10/25/2021), the firm sent an "Urgent Medical Device Correction" Notification to customers via email to inform them that it has identified an imprecision at top of calibration curve, where the calibration curves produced using specific lots have a higher activity than routinely expected and that there may be a decrease separation between calibrator point 5 and 6 which can be exacerbated when calibrator 6 activity reaches the optical ceiling of the analyzer and may result in an inaccurate value being reported. Customers are instructed to: Adapt the calibration curve to run as a 5-point curve with immediate effect as below 1. Stop using the 6-point calibration curve for the affected kit lots. 2. Run a 5-point calibration curve by entering values for Calibrator 1 to Calibrator 5 only as found on the Quality Control Certificate provided within the kit in ascending order on Page 1 of the Item parameters. Leave Standard 6 blank. Ensure the Auto Fill button is pressed after entering the value for Calibrator 5 on page 1. The analyser will automatically calculate and enter the revised measuring ranges on Item pages 3 and 4. 3. View Item parameter pages 3 and 4 to ensure correct value entry. 4. Before requesting calibration, view the CALIB screen and delete any existing rack position and OD information shown for STD-6 of the corresponding assay. 5. Calibration curves must only be accepted if Absorbance values increase with increasing concentration as stated in Section D.2.2 of the SPAPLUS Reference Guide (FIN012). -The expiry of the above kit lots has been reduced from 31/OCT/2022 to 30/APR/2022. Update records accordingly as the affected kit lots must not be used beyond this point. 6.
