![]() WHAT'S THE DIFFERENCE BETWEEN TRADITIONAL BLOOD GLUCOSE TESTING AND FLASH GLUCOSE TESTING?įinger prick blood glucose readings and sensor glucose readings won't always match and in fact are likely to be different. This means that it is calibrated at the factory - so you do not need to calibrate it again. The FreeStyle Libre sensor is made by a process which means the sensitivity of the sensors varies very little. WHAT DOES 'NO USER CALIBRATION' MEAN?Ĭalibration, sometimes called coding is needed because the sensitivity of each sensor can vary within each batch that is made. ![]() As it is made by a process which means the sensitivity of the sensors vary very little - it is calibrated at the factory. You do not need to calibrate the FreeStyle Libre sensor with a finger prick. The FreeStyle Libre sensor is water-resistant and can be worn on the back of your arm for up to 14 days whilst you shower, bathe, swim, exercise or play. This means that for a complete glycaemic picture, you only need to scan once every 8 hours– enabling you to make more informed decisions about how you manage your diabetes. It continuously measures the glucose concentration in your interstitial fluid, and stores 8 hours of data. You can scan as many glucose readings as you want whilst the sensor is being worn – it even scans through clothes! Unlike traditional blood glucose monitoring, using the FreeStyle Libre sensor does not involve painful routine finger pricks. ![]() The Sensor has a small, flexible tip that is inserted just under the skin. It is worn on the back of your upper arm and lasts for up to 14 days. The FreeStyle Libre sensor’s small size makes it discreet to wear.

These effects of such deviations can partly be overcome by optimizing the available user instructions.īlood Glucose Self-Monitoring Continuous Glucose Monitoring Endocrinology Diabetes Glucose Control. Following a standardized glucose load, a slower rise in glucose level was observed for FSL-CGM arm as compared with PCA-HK, StatStrip, FSLC, and iPro2 during the first 45-60 min after glucose load ingestion.Ĭertain matters need attention while using the FSL-CGM in daily life including the observed lower values in the lower ranges, and the underestimation of the effect of a meal on glucose response. The overall correlation of FSL-CGM in the arm and the StatStrip indicates a performance with lower results with the FSL-CGM in the arm than expected based on the StatStrip in the lower glucose ranges, and higher results than expected in the higher ranges. ![]() For FSL-CGM abdomen and FSLC, these percentages were 64% and 98%, respectively. The glucose response after a standardized oral glucose load was measured by FSL-CGM and capillary samples analyzed by perchloric acid hexokinase (PCA-HK) method, StatStrip and FSL test strip (FSLC), and a commonly used CGM system (iPro2).įSL-CGM arm sensor readings showed 85.5% of paired readings falling within Clarke Error Grid (ISO 15197:2013) zone A when compared with StatStrip. FSL-CGM sensor measurements (inserted in arm and abdomen) were compared with capillary blood glucose results analyzed with StatStrip as semigold standard. To evaluate the performance of the FreeStyle Libre Flash continuous glucose monitoring (FSL-CGM) system against established central laboratory methods.Ģ0 subjects (8 type 1 diabetes mellitus, 12 type 2 diabetes mellitus) were analyzed. ![]()
