The system labeling (user manual and online labeling) did not provide adequate directions for lay users to act on the E-5 error code. The error code description and recommended actions for the E-5 error code in the labeling do not: (a) clearly emphasize that an E-5 error code could represent a very high blood glucose level, and (b) prominently convey the appropriate immediate actions, such as contacting a healthcare professional. This could lead to a delay in treatment if the user does not seek medical attention immediately when receiving an E-5 error code and experiencing symptoms of high glucose.

Philips Connected Blood Glucose Meter, BGM 4; Model Number: TM0009;
Telcare, LLC has received customer complaints related to battery expansion/swelling for its Philips Connected Blood Glucose Meter (i.e., BGM 4 brand name) Monitoring System.. The issue was identified by post market surveillance data (customer complaints) - events of battery expansion/swelling and associated symptoms, e.g., leading to the device's removable back cover (battery port) to separate. If there is a loss of primary function of the device due to the described device defect, an immediate health consequence that may result is prolonged hypoglycemia or hyperglycemia due to delay in treatment, as the blood glucose measurement is not available to guide treatment. In a worst-case situation, there is potential for battery swelling to result in explosion of the battery and/ or device. Exposure to explosion, and subsequently projectiles from the explosion, may result in several immediate health consequences, including concussion, headache, dizziness, eye irritation, blurred vision, eye injury, and vision impairment.

Accu-Chek Guide (SC) Kit -Intended to quantitatively measure glucose in fresh capillary whole blood from the fingertip, palm, and upper arm as an aid in monitoring the effectiveness of glucose control. Product REF Number: 08453071001
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.

Contour next GEN Blood Glucose Monitoring System
Ascensia Diabetes Care has determined through customer complaints that 580 of 2900 meters from lot number DM01T033P are reconfigured from mg/dL to mmol/L. Among them, 579 meters distributed in the United States were packaged into the meter kit and had incorrect factory-set unit of measure where the meters display glucose results in mmol/L rather than mg/dL. The standard unit of measurement for the United States is mg/dL. If a consumer does not notice the incorrect unit of measurement, it is possible that the meters glucose measurement will be read as a lower blood glucose measurement than expected, and this may result in the patients glucose level remaining high, which can potentially lead to an injury requiring immediate medical intervention.
