A1CNow+ Multi-Test HbA1c System consists of (1) a semi-disposable plastic-encased device (the monitor), (2) a plastic cartridge enclosing dry reagent strips, an

The reason for this recall is PTS Diagnostics, Inc. received complaints of non-matching cartridge and analyzer codes within the product test system box. Use of cartridges and analyzers with non-matching codes may result in inaccurate test results as components within each lot number are meant to be used together, and not mixed between lots. Therefore, the test results may possibly lead to Hemoglobin A1C positive or negative bias results. While the product is for monitoring only, over recovery with a higher than accurate value can be an indication for increased therapy; such as physical activity, weight reduction, meal management, pharmaceutical therapy.

Five Afinion 2 (AF2) Analyzer were incorrectly market configured as Moderate Complexity and distributed to customers. Use of moderately complex assays by waived laboratories could result in erroneous results.

DCA Systems HbA1c Reagent Kit

The reason for the recall is that the Siemens DCA HbA1c Reagent Kit was confirmed to display a positive bias without alerting the user. The potential impact of the defect is that erroneous test results could be reported and potentially lead to incorrect patient management of glucose control. A positive bias may be observed with eleven HbA1c affected lots. Positive bias was observed when the performance of these five HbA1c lots was compared to NGSP pooled patient target-value assigned samples and the maximum bias observed was 19%.

Tina-Quant Hemoglobin A1c Gen. 2

Roche Diagnostics has confirmed elevated QC and patient sample recovery for individual Tina-quant Hemoglobin A1c Gen.2 and Tina-quant Hemoglobin A1cDx Gen.2 cassettes/bottles. This issue occurred over multiple lots. Single cassettes/bottles of the reagents are affected. The issue can lead to erroneously high HbA1c results. If a patient with known diabetes is affected, an erroneously high HbA1c result might lead to therapeutic consequences, such as therapy escalation (introduction of another oral antidiabetic medication or insulin) or increase of the dosage. This can further lead to an increased risk of hypoglycemia. Considering the unreliable detectability of the issue, relevant medical risk for the patient cannot entirely be excluded.

Reagent in these lots may demonstrate an increased occurrence of high %HbA1c bias, a positive bias averaging 0.6% HbA1c units, ranging from -0.1% to 1.1% HbA1c units. The maximum bias was observed at higher %HbA1c concentrations. QC samples may exhibit a similar bias.
