Class II — the FDA judged the product may cause temporary or medically reversible harm, with a remote chance of serious harm.
This is the FDA's risk judgment for this recall. It describes the potential of the product as a category — it does not establish that any specific unit harmed anyone. Most recalls are Class II or III.
A1CNow+ Multi-Test HbA1c System consists of (1) a semi-disposable plastic-encased device (the monitor), (2) a plastic cartridge enclosing dry reagent strips, and (3) a sample dilution kit for: collecting the blood sample, mixing the sample with the required pre-treatment solution, and delivering the sample to the cartridge.
Why it was recalled
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.
Is your unit affected?
The recall covers only the specific lots or serial numbers the FDA listed. Enter the lot or serial number from your product's label and we'll check it against that list.
A match means your unit may be covered — stop and call your pharmacist before doing anything. No match suggests it isn't covered, but confirm anyway: code formats vary and lists can be incomplete. Your unit not being listed does not guarantee it is safe, and being listed does not mean you have been harmed.

What this is — and is not
A recall is a recorded FDA enforcement action — the FDA logged that a firm is removing or correcting a product. It does not establish that any specific unit harmed anyone, and causation is not established by a recall. The class above is the FDA's risk judgment for the product category, not a finding about your unit. This page informs and compares; it is not medical advice and never tells you to start or stop a drug or device.
