Self-monitoring of blood glucose (SMBG) both in insulintreated and non-insulin-treated people with diabetes is supported by recently published trials, reviews, meta-analyses, and guidelines. [1][2][3][4][5][6][7] SMBG is recommended to be performed in a structured approach. 2,5,8,9 It is reported to be only useful when blood glucose (BG) data are interpreted and utilized for immediate therapeutic actions. 3,4,[10][11][12][13] For instance, the need for adequate dosing of insulin heavily depends on reliable glucose information. 8 In particular, patients with insulintreated diabetes perform SMBG as a substantial element of daily management of diabetes.14,15 The term "BG system" denotes the combination of a BG meter and test strips, and both determine analytical performance. 8 The analytical and handling performance of BG systems has largely improved over the past decades. In addition, the implementation of inmeter safety features (ie, validity of test strips check) has further increased the safety of these devices. 16 Consequently, patients with appropriate training and a good performance of BG testing can typically rely on the precision of BG measurement results. However, in the daily practice a range of factors with potential impact on the reliability of BG measurement needs to be considered. In fact, this is an important aspect in field of point-of-care (POC) testing. 17 Members of the diabetes team and patients should be well informed about all factors potentially falsifying BG measurement results: human, meter-inherent, test-strip-inherent, environmental, physiological, and medication-related impact factors (Table 1).The risk of misinterpretation of BG readings can be minimized by detailed information on the factors potentially affecting BG measurement. Hence, the aim of this publication is to review the current knowledge on limitations and interferences significant for reliable BG testing.Nonetheless, due to the rapid technological progress, it should be kept in mind that performance of most more recent BG meters may not always be reflected by the reviewed literature, since it reports on data generated with older BG generations. 17 Moreover, it is important to note that some studies on limitations of BG meters were performed under extreme conditions which do not comply with the approved conditions of usage. AbstractIn general, patients with diabetes performing self-monitoring of blood glucose (SMBG) can strongly rely on the accuracy of measurement results. However, various factors such as application errors, extreme environmental conditions, extreme hematocrit values, or medication interferences may potentially falsify blood glucose readings. Incorrect blood glucose readings may lead to treatment errors, for example, incorrect insulin dosing. Therefore, the diabetes team as well as the patients should be well informed about limitations in blood glucose testing. The aim of this publication is to review the current knowledge on limitations and interferences in blood glucose testing with the perspective of the...

“…[8][9][10][11] Data from computer simulations have shown what enormous impact the total analytical error of BG meters can have on clinical decision-making and on glucose control. [12][13][14] The aim of this study was to investigate the accuracy of SMBG values in children and adolescents with type 1 diabetes by comparison with laboratory-obtained glucose levels measured in parallel and to identify possible effects on both glucose control and hypoglycemic events.…”

“…[1][2][3][4] As SMBG systems are used to make therapeutic decisions, accuracy is an important issue to avoid improper actions. 5,6 The accuracy of SMBG systems is often assessed by using the protocol stated in the International Organization for Standardization (ISO) standard 15197. 7,8 According to the system accuracy criteria of the 2003 version, at least 95% of individual meter results must fall within -15 mg/dL of the comparison method result for blood glucose (BG) concentrations < 75 mg/dL and within -20% for BG concentrations ‡ 75 mg/dL.…”
