Product Description

The VerifyNow P2Y12 Test is designed to measure platelet P2Y12 receptor blockade. Substances known to specifically block the P2Y12 receptor include ticagrelor and the thienopyridine class of drugs, including clopidogrel and prasugrel.1-8 The test is based upon the ability of activated platelets to bind fibrinogen. Fibrinogen-coated microparticles aggregate in whole blood in proportion to the number of expressed platelet GP IIb/IIIa receptors. Light transmittance increases as activated platelets bind and aggregate fibrinogen-coated beads. The instrument measures this change in optical signal and reports results in P2Y12 Reaction Units (PRU). The rate of microbead aggregation is more rapid and reproducible if platelets are activated; therefore, the reagent adenosine-5-diphosphate (ADP) is incorporated into the test channel to induce platelet activation. Prostaglandin E1 (PGE1) is included in the reagent mixture to increase the specificity of the PRU result to reflect P2Y12-mediated platelet aggregation. The reagents are formulated such to achieve reaction concentrations of 20 ¿M ADP and 22 nM PGE1. In a like manner, two other activators, iso-TRAP (Thrombin Receptor Activating Peptide) with PAR4-AP (PAR4-Activating Peptide) and fibrinogen-coated microparticles are incorporated into a second channel of the test device. The instrument measures the change in transmittance in this channel, calculates the baseline platelet function for the sample, and reports the percent inhibition result for the sample.

Reason for Recall

Two whole blood Platelet Reactivity tests exist that share the same reagent formulation and are used to obtain P2Y12 Reactivity Unit results. The test without US-FDA market clearance was distributed and it displays BASE results not displayed by the US-FDA market cleared device. A formula is being provided to health care personnel to calculate the percentage of platelet aggregation inhibition.

Distribution Pattern

US Nationwide distribution in the state of California.

Frequently Asked Questions

Contact your healthcare provider and the device manufacturer immediately. Check whether your specific model number and lot number are included in the recall scope. For external devices, stop using the affected product and arrange a replacement. For implanted devices, do not panic — removal is typically not required unless the risk assessment clearly indicates it. Your physician will guide you based on your individual clinical situation and the FDA's recommended actions. Report any adverse effects you may have experienced to FDA MedWatch at 1-800-FDA-1088.

Class I recalls indicate a reasonable probability of serious adverse health consequences or death from the defect. Class II recalls involve products that may cause temporary or medically reversible adverse health consequences, or where serious consequences are remote. Class III recalls cover products not likely to cause any adverse health consequences, typically involving technical regulatory violations. The classification guides urgency — Class I recalls require immediate action, while Class III may simply involve returning a product or acknowledging a labeling change. Always read the specific recall notice for recommended patient actions.

Report problems with medical devices to the FDA through MedWatch at 1-800-FDA-1088 or online at FDA.gov/safety/medwatch. Healthcare facilities are required by law to report device-related serious injuries and deaths. Patients and consumers can also report voluntarily. Include the device name, manufacturer, model number, and a description of the problem and any patient outcome. Reports from patients and clinicians help the FDA identify emerging safety signals and may trigger investigations that lead to recalls of dangerous devices.

What Should You Do?

Stop using this device if you are affected by this recall. Contact your healthcare provider and the manufacturer immediately for guidance. Report adverse events to FDA MedWatch.
