The agency’s classification
FDA (Devices): Class I
Class I is a situation in which there is a reasonable probability that the use of or exposure to a violative product will cause serious adverse health consequences or death.
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.
Our severity reasoning: The agency classified this recall as Class I — a situation in which there is a reasonable probability that the use of or exposure to a violative product will cause serious adverse health consequences or death. On that classification alone this is scored Severe; a score of Critical is reserved for recalls where a death or serious injury was reported. The agency gives the reason as: "Alere San Diego is initiating a voluntary recall for the Alere INRatio¿/INRatio¿2 PT/INR Monitoring Systems (Test Strips and Meters). This action is being initiated as a result of patients who had a therapeutic or near-therapeutic INR with…"
Plain-English summary
Alere San Diego, Inc. is initiating a voluntary recall of the Alere INRatio and INRatio2 PT/INR Monitoring Systems, which include test strips and meters. The recall covers model numbers 0100071 and 0100139. The products were distributed worldwide, including in the United States and numerous foreign countries.
The recall is being conducted because patients using the Alere INRatio or INRatio2 system received therapeutic or near-therapeutic INR results, but subsequent testing by a central laboratory revealed significantly higher INR values that were outside the therapeutic range. This discrepancy indicates that the device may not accurately reflect the patient's coagulation status.
The source text does not specify the number of affected units, specific lot numbers, or dates of distribution. Consumers and healthcare providers should stop using the recalled test strips and meters and consult their healthcare provider for alternative INR monitoring methods.
