  • Reason
    In december 2014 (tga ref: rc-2014-rn-01289-1), alere initiated a correction to inform users of the alere inratio system that patients with certain medical conditions should not be tested with the system due to the potential, in certain cases, of the alere inratio system to provide an inr result that was significantly lower than a result obtained using a laboratory inr system. alere has recently decided to remove the alere inratio system from the market and to discontinue manufacturing the product line. alere will continue manufacturing and distributing the alere inratio test strips for a period of time to allow patients to safely transition to another monitoring method.
  • Action
    Alere is advising customers to transition to an alternative method to perform PT/INR testing as soon as possible. Alternate methods may include a plasma-based laboratory INR method or monitoring with a point-of-care system from a different manufacturer. After transitioning onto another system, the Alere system and remaining test strips must be returned to Alere. Customers can continue to use the Alere INRatio System until users have transitioned, as long as patients adhere to the precautions and recommendations found in the 2014 Recall for Product Correction letter and the current product insert.

  • Manufacturer comment
    “We are in constant communication with regulatory agencies and competent authorities worldwide which allows us to implement global recalls or in-country communication quickly and effectively,” Abbott, which now owns St. Jude Medical told ICIJ in a statement. In addition to sending global notices to physicians worldwide, we also make sure that product advisories are available online and classification of product recalls and product advisories are determined by global regulatory bodies which can impact the timing in any given country. MD companies follow varying regulations in different countries. In come countries software is not regulated so a recall in one country related to software would not be classified as a recall or field action in another. In addition, review cycles within the regulatory process can be different in each country which can impact communication and recall timing.
