Background:
Home glucose monitoring system is increasingly recognized as an important tool for glycemic control. We evaluated the clinical performance of the eBsensor glucose monitoring system.
Methods:
Fingertip capillary blood glucose concentrations from 282 subjects were measured using eBsensor glucose monitoring system and compared against predicate devices and the Yellow Springs Instruments (YSI) 2300 blood glucose analyzer. Accuracy and precision of the eBsensor glucose monitoring system were assessed using several methods. The comparative study between the eBsensor and 2 currently marketed monitoring systems was performed.
Results:
The 282 eBsensor readings covered a wide range from 2.6 to 24.4 mmol/l. Deming regression and Pearson correlation analyses showed a linear relationship between the eBsensor readings and the YSI reference method (eBsensor=0.9496 YSI+0.4127 mmol/l; r=0.98). Error Grid analysis demonstrated that 100% of the eBsensor readings in clinically acceptable zones A and B. The CVs for the 6 lots of strips were within the satisfactory interval (<6%). The comparative study showed that the eBsensor readings correlated well with the OneTouch Ultra values (r=0.97) and the Glucocard II values (r=0.97).
Conclusions:
eBsensor is a reliable glucose monitoring system which provides high accurate and precise glucose readings over a wide range of glucose concentrations.

Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.

01:30Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
