How to avoid mistakes when measuring blood glucose

Avoid mistakes / measure exact


How to begin	Wash and dry your hand thoroughly Check the shelf life time of the test strips (you find them on the label of the test strip vial) Keep the On/Off button pressed when switching on the device and check the correct function of the display. Release the button. The meter is ready for testing. If "E-1" (Error Message: Meter temperature exceeds the usage temperature from 10°C -35°C) is displayed, go to a place within the usage temperature. Do not try to warm up (hair-dryer) or cool (refrigerator) the meter. If the meter a fast change of temperature (from inside to outside), leave the meter at least 5 min (optimal 30 min) to be adopted to the temperature of the environment, before making the next measurement . When measuring, avoid places where the wind goes, in front of a heater or a climate device, where many people are together.

Check calibration	Check if the code on the test strip vial, you want to withdraw the test strip, matches the one displayed on the meter. If the code do not match, hold the C-button pressed and adjust the code with the > button. TIP: Hold the > button pressed and the Code increases faster. Release the C-Button.

Insert test strip	Insert the test strip with the gold contacts forward and the print facing up into the meter. When correctly inserted a signal resounds Do not insert the test strip several times into the meter! Multiple insertions risk to damage the test strip contacts

Puncture Read to the subject "puncture" also the "hints for using the lancing device "	Unscrew the lancing device Insert a new, sterile lancet Unscrew the protective cap Screw the lancing device and draw the lancing device Leave the hand you want to use for the puncture hang down or throw the hand (this increases the blood presence in the fingers and eases taking the blood probe) Check the adjustment of the lancing device with the setting ring gage Level 3 for normal skin (AutoLancet lancing device) If the puncture hurts, try a lower setting. Use the 3-time facetted GlucoSmart lancets Trigger the lancing device Avoid the sensitive fingertip, do the puncture at the side of the finger Use preferably not the thumb or forefinger, which you use for handling parts.

Probe gathering	Use both thumbs to press slightly the blood from the base of the finger in direction to the puncture until a little blood bowl is available. Do not press directly at the puncture to avoid pressing out lymph fluid, which can falsify the measurement. Lead the test strips capillary side wards to the blood bowl with the test strip nearly parallel to the surface of the skin for to keep the capillary open. The opening of the capillary of the test strip is marked by the pointing finger sign. If blood is absorbed fast until the measurement countdown starts, the statistic deviation of the measurement result will deviate only very little from a reference measurement (at GlucoSmart normally below 5% For information: The measurement results of blood glucose meters for self use are according to Norm EN ISO 15197:2003 by 95%: - when the measurement range is < 75mg/dl (4,2mmol/l): within +/- 15mg/dl (0,83mmol/l) and - when the measurement range is >/= 75mg/dl (4,2mmol/l) within +/- 20% from the laboratory reference value (target). Notices:. Customer complaints about the exactness have their reason mostly in the wrong angle of the test strip to the blood bowl. (At right angle to the surface is wrong! This will eventually close the opening of the capillary). A sufficient size of the blood bowl drawn without interruption within the capillary is the precondition for an exact measurement result. As the measurement process starts up with the blood entering the capillary, no second try is allowed to complete the filling, because this would falsify the measurement result! If the big sight window is not filled completely, repeat the measurement with a new test strip. Sufficient blood for a correct measurement was provided, if right, big control window is completely filled (2,5µl blood probe). Therefore control the big sight window. if the left small window is also filled, 4µl blood were drawn into the test strip capillary. Place the meter during the measurement countdown carefully. A shock or vibrations might cause false measuring results.
