transit delays of certain cold chain products due to severe thunderstorms which may caused the products to be stored outside the recommended labeled storage conditions. This failure could increase the probability of an incorrect test result or a delayed test result.

Randox Laboratories has identified that Inorganic Phosphate in Calibration Serum Level 3, CAL2351 & CAL10388, is running with a negative bias on RX Series instruments compared to other methods.

The firm has realigned C3 and Haptoglobin in Liquid Protein Calibrators, IT2691, to reference material ERM-DA470k/IFCC.

Target for Alkaline Phosphatase (ALP) for the AMP optimized to IFCC 37¿C method has been mis-assigned for the RX Series instruments by approximately 10% on Quality Control and patient samples

CK Total in Calibration Serum Level 3, CAL2351, is running with a positive bias on RX Series instruments compared to other methods experience a shift in Quality Control and patient sample recovery of up to 13%.

There have been transcription errors on the Instructions For Use (IFU) of the Calibration Serum Level 3 (CAL2351 lot 1260UE, 1262UE and 1315UE) for target values of Bilirubin and Triglycerides, on the IFU of Human Assayed Multi-Sera Level 2 (HN1530) for TBIC taget value and on IFU of Human Assayed Multi-Sera Level 3 (HE 1532) for Lipase target value.

RAPIDPoint 500 Systems Measurement Cartridges (with lactate) has the potential to affect the Sodium (Na+) sensor to produce a negative bias that could result in serious injury due to a delayed diagnosis of hypernatremia or unnecessary intervention for hyponatremia and result in iatrogenic hypernatremia especially if the true sodium result is near the thresholds of severe alterations, as well as cause a Question Result -----? error flag for multiple electrolytes on patient samples and quality control that may cause a delay of diagnosis or treatment.

As part of the firm's ongoing quality monitoring (see internal complaint # OCC72574), Randox Laboratories have restandardized Ferritin in Liquid Protein Calibrators, IT2691, to reference material NISBC 19/118. The calibrators lots 2112IT-2116IT, packed into batches 627222, 627224, 634886 and 634887 have been reassigned as part of the restandardization. Following this restandardization, Ferritin results for Quality Control material and patient samples recovered erroneously higher than the targeted calibrator values by approximately +10% across the assay range following.

Randox can confirm a positive bias for Total Bilirubin and Direct Bilirubin of up to +15% across the assay ranges when using calibrator CAL2351, lot 1162UE. The positive bias has been attributed to bilirubin instability in the calibrator and is evident in both Quality Control (QC) and Patient samples.

Potential total iron-binding capacity (TIBC) results. The VITROS TIBC performance shift will start with the newest Generation (GEN) of VITROS Fe Slides (GEN 26), the potential shift in TIBC patient values of GEN 26 and above will be approximately 80 ug/dL lower across the measuring range than other available GENS of VITROS Fe Slides (GENs 22-25).

Products do not meet stability criteria and may impact results.

Calibrator lots may not meet stability criteria and could result in increased results of patient samples for cortisone.

Atellica CH: The Atellica¿ CH High Sensitivity CReactive Protein Calibrator (hsCRP CAL) is for in vitro diagnostic use in calibrating the hsCRP assay using the Atellica¿ CH Analyzer.

Atellica and ADVIA hsCRP calibrator accuracy has drifted away from the reference materials (ERM-DA470/IFCC), which is causing a high bias on QC and patient sample recovery.

The assigned value for Rheumatoid Factor over recovers against the reference material RF serum, 1st British standard from NIBSC. Ref = 64/002. The calibrator values have been adjusted to re-align to the reference material.

Randox Laboratories realigned RX Analyser Series calibration targets by 10% for AST and 9% for ALT in line with the Mean of All Instrument method target for the Randox Calibration Serum Level 3 (for calibrator lot 961UE onwards).
