Cystatin C Reagent marketed without a 510 (k)

Foam gasket on the Evidence MultiSTAT chip heater assembly may not perform as expected. Foam that is not functioning as expected may cause light to leak into the Charged Coupled Device (CCD) Camera during imaging. This will affect the testing and may delay in reporting results.

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.

Microalbumin Calibrator Series, MA1567 & MA2426, is running with a negative bias compared to other method may misclassify patient results. Users may experience a shift in Quality Control and patient sample recovery of up to +12%.

Cystatin C Calibrator Series CVS 2699, is running with a negative bias compared to other methods

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

Randox Laboratories have released an update to the Carryover Avoidance Technical Bulletin to detail that Copper, should not be run directly after Total Protein, on the RX series instruments testing order. If copper assay is run after total protein it could lead to falsely elevated copper results.

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.

A decrease in the reactivity of HSV Type 1/2 lgM in the Serology ToRCH lgM Positive Control when tested on the DiaSorin Liaison XL.

Randox has had reports of elevated patient results using Plasma (lithium heparin) samples with Total Bilirubin reagent (TBil) Vanadate Oxidation Method.

RX Parameter rerun settings (Sample Volume Low/High), and Dilutions used for Auto reruns, not meeting sample re-run conditions when samples are above or below assay range and may result i issues with the re-run feature conditions when incorrectly. Potential to report incorrectly.

there has been a transcription error in the Instructions for Use (IFU) for the Liquid Assayed Chemistry Control Premium Plus Level 3. For Caeruloplasmin, the one and two standard deviation values printed on the sheet are incorrect, which may lead to misreporting patient results. Target and range values are correct, and risk is mitigated; most clinical labs will use the target and range values in clinical practice.

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.

(1) There is vial to vial variation resulting in some vials recovering positive for hCG, which should be negative and (2) high and outside range for cortisol. (3) There has been a transcription error for Creatinine in the Instructions For Use (IFU). The target and ranges for Creatinine for the Roche Creatinine Plus method have been listed incorrectly. These failures cause a delay in patient results for the above mentioned analytes.

Carryover from the Direct LDL-cholesterol assay on the Rx instruments may result in a negative bias, up to -11%, in quality control and patient samples, in urea assays results if the urea assay is run immediately after the Direct LDL-cholesterol assay. This may lead to a delay in reporting results or in falsely decreased urea test results.

Delay in reporting results due to Quality Controls running high outside of range. Target value and range for ACTH in Immunoassay Premium Level 3, IA2640, lot 2031EC and Immunoassay Premium Control Tri Level kit batch 583135 lot 2031EC has been reassigned on the Roche Cobas e801 due to High recovery outside range
