The problem relates to a defect that inhibits sufficient absorption of blood into the test strip. Strips exposed to warm weather or prolonged storage may be more likely to provide a false result. Test strips with lot numbers that have been recalled may give falsely low blood glucose results, which can lead patients to try to raise their blood glucose when it is unnecessary, or to fail to treat elevated blood glucose due to a falsely low reading. Both scenarios pose risks to health.
These strips are used with Abbott's Precision Xtra, Precision Xceed Pro, MediSense Optium, Optium, Optium EZ and ReliOn Ultima blood glucose monitoring systems. As many as 359 million strips may be affected by the recall. The test strips, which were manufactured between January and May 2010, are sold both in retail and online settings directly to consumers, but are also used in health care facilities.
