Accu-Chek Performa II Meter - Product Usage: a. The Accu-Chek Aviva Plus Blood Glucose Monitoring System is intended to be used for the quantitative measurement of glucose (sugar) in fresh capillary whole blood samples drawn from the fingertips, forearm, upper arm, or palm. The Accu-Chek Aviva Plus Blood Glucose Monitoring System is intended to be used by a single person and should not be shared. b. The Accu-Chek Aviva Plus Blood Glucose Monitoring System is intended for self-testing outside the body (in vitro diagnostic use) by people with diabetes at home as an aid to monitor the effectiveness of diabetes control. The Accu-Chek Aviva Plus Blood Glucose Monitoring System should not be used for the diagnosis of or screening of diabetes or for neonatal use. Alternative site testing should be done only during steady state times (when glucose is not changing rapidly). c. The Accu-Chek Aviva Plus Test Strips are for use with the Accu-Chek Aviva Blood Glucose Meter to quantitatively measure glucose (sugar) in fresh capillary whole blood samples drawn from the fingertips, forearm, upper arm, or palm.

The reason for recall is the meters may show an incorrect measurement unit (mmol/L rather than mg/dL) and may result in the wrong unit of measure. Which may subsequently cause an error in interpreting a result as approximately 18 times lower that the actual blood glucose. Potential immediate health consequences of the glucose meter providing a reading in the wrong units of measurement (UOM) may result in inappropriate rescue therapy for presumed hypoglycemia including urgent and repeat administration of carbohydrates. This in turn could lead to frequent episodes of hyperglycemia which is unrecognized and undertreated.Long range consequences of continued use of the affected meters could include mismanagement of the patient s diabetes for longer periods of time potentially resulting in a major health event (in general persistent and/or severe hyperglycemia) that may lead them to seek medical attention, and depending on the duration of hyperglycemia, could contribute to the development of microvascular (i.e., retinopathy, neuropathy, nephropathy) and/or macrovascular (i.e., myocardial infarction, ischemic stroke) complications of diabetes and could lead to fetal damage (abnormal fetal growth and altered organ development and maturation, fetal hypoxemia, spontaneous abortion, and congenital anomalies) in pregnant women. This issue was identified by three initial consumer complaints, with reports that the meters were presenting the incorrect unit of measure.

Test strip vials may open while inside sealed cartons during shipment. An open vial might expose the test strips to humidity, which might damage the strips and result in inaccurate results, potentially leading to inappropriate therapy decisions and adverse health consequences.
