Glucose monitoring at the arm: risky delays of hypoglycemia and hyperglycemia detection

OBJECTIVE: We have examined whether rapid changes in blood glucose (BG) result in clinically relevant differences between capillary BG values measured at the forearm and the fingertip and whether local rubbing of the skin before blood sampling can diminish such differences. RESEARCH DESIGN AND METHODS: Capillary BG samples were collected every 15 min for 3-5 h from the fingertip and the forearm of 17 insulin-treated diabetic patients and analyzed with different glucose monitors (FreeStyle, One Touch Ultra, and Soft-Sense). In a subgroup of patients (n = 8), local rubbing of the forearm skin was performed before blood sampling. A rapid increase in BG was induced by oral administration of glucose, and subsequently, a rapid decrease in glucose was induced by intravenous administration of insulin. RESULTS: In the fasting state, the BG values at the fingertip and at the forearm were similar (7.8 +/- 2.4 vs. 7.2 +/- 2.3 mmol/l, P = 0.06). However, during rapid increase in glucose, BG values at the fingertip were consistently higher than at the forearm (maximal difference 4.6 +/- 1.2 mmol/l, P < 0.001). During rapid decrease in glucose, lower BG values were recorded at the fingertip (maximal difference to forearm 5.0 +/- 1.0 mmol/l, P < 0.001). At the forearm, BG was delayed by a median of 35 min (P < 0.01) in relation to the fingertip. Rubbing of forearm skin decreased the observed differences but with a large intraindividual and interindividual variability. There were no obvious device-specific differences. CONCLUSIONS: To avoid risky delays of hyperglycemia and hypoglycemia detection, BG monitoring at the arm should be limited to situations in which ongoing rapid changes in BG can be excluded.

Correlation of fingerstick blood glucose measurements with GlucoWatch biographer glucose results in young subjects with type 1 diabetes.

OBJECTIVE: The purpose of this study was to compare measurements of glucose obtained via iontophoretic extraction with the GlucoWatch automatic glucose biographer (Cygnus, Inc., Redwood City, CA) with capillary blood glucose values that were determined 1) in a controlled outpatient clinic setting and 2) in a home setting. RESEARCH DESIGN AND METHODS: There were 76 GlucoWatch biographers used on 28 different young adults (21 women and 7 men) with type 1 diabetes (age 30.9 +/- 6.9 years and duration of diabetes 18.4 +/- 8.1 years [mean +/- SD]) in a controlled outpatient clinic setting. Some subjects participated on multiple days. Subjects wore two GlucoWatch biographers, each on the forearm (ventral aspect). Comparisons were made to HemoCue blood glucose analyzer (Aktiebolgat Leo, Helsingborg, Sweden) capillary blood glucose measurements. In addition, GlucoWatch biographers (one each day for 3 consecutive days) were used by 12 subjects (8 women, 4 men) in a home setting. Comparisons were made to capillary blood glucose values determined using the One Touch Profile meter (Johnson & Johnson, New Brunswick, NJ). RESULTS: GlucoWatch biographer glucose values correlated well with capillary blood glucose values determined using the HemoCue analyzer in the clinic setting (r = 0.90, 1,554 paired data points) and using the One Touch Profile meter in the home setting (r = 0.85, 204 paired data points). When 36 subjects wore two biographers simultaneously, the correlation between the two biographers was r = 0.94. The error grid analysis demonstrated that > 96% of biographer glucose values determined in the clinic or home setting were in the clinically acceptable A and B regions. CONCLUSIONS: This study confirms the accuracy and precision of glucose values as determined using the GlucoWatch biographer in clinic and home settings.     

Accuracy of home blood glucose monitors.

OBJECTIVE--To determine the accuracy of five home blood glucose monitors (HBGM) in reference to a standard laboratory reference method. RESEARCH DESIGN AND METHODS--The study took place in the laboratory of a 350-bed private acute-care hospital. Subjects were a sample of convenience of 207 diabetic and nondiabetic adult and pediatric patients scheduled for fasting blood work that included a blood glucose test. Venous blood samples were collected for laboratory determination of blood glucose level. A separate sample was collected for testing on two each of five HBGMs: AccuChek II M, Tracer II, ExacTech, Glucometer II with Memory, and One Touch. RESULTS--Multiple regression analysis showed that all 10 monitors could be used to predict laboratory blood glucose values. The monitors with the highest predictabilities were One Touch, Tracer II, and AccuChek II M. Consistency between monitors of the same brand was lowest with One Touch. AccuChek II M had the smallest SD between the 2 monitors used in the study. CONCLUSIONS--HBGM can be used to predict actual laboratory values of blood glucose. However, the controlled environment of the study should be considered and patient education made a high priority when recommending monitors.
