This is the agency’s own classification, taken from its notice. The severity score below is our assessment, not the agency’s. How recall classes work
What this means for you
Our assessment, not the agency’s: severity 4/5 (Severe).
The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.

Plain-English summary
Alere San Diego, Inc. is initiating a voluntary recall of the Alere INRatio and INRatio 2 Prothrombin Time (PT) Monitoring Systems, including test strips and meters. The recall covers all lots and serial numbers of the affected models.
The recall was initiated because patients using the INRatio systems received therapeutic or near-therapeutic INR results, but subsequent tests performed by central laboratories showed significantly higher INR values outside the therapeutic range. This discrepancy indicates that the device may not be accurately measuring the patient's coagulation status.
The product was distributed worldwide, including in the United States and numerous foreign countries. Patients using these devices should consult their healthcare providers regarding their anticoagulant therapy and follow instructions for proper monitoring.
