Comparing your meter and laboratory results
Test results with the EasyTouch® BluLink® Blood Glucose Monitoring System are
plasma-equivalent. This method will help you and your Healthcare Professional
compare your meter results with laboratory test results. The EasyTouch® BluLink®
test results and laboratory test results both are expressed in plasma-equivalent
units. However, your glucose monitor results may differ from your laboratory
results due to normal variation. Your glucose monitor results can be affected by
factors and conditions that do not affect laboratory results in the same way.
The following may affect the accuracy of your meter:
• You are severely dehydrated.
· You have eaten recently. The blood glucose level from blood obtained from a
fingertip can be up to 70mg/dL higher than blood drawn from a vein (venous
sample) used for a lab test.
• Your hematocrit is above 55% or below 30%.
If you perform a blood sugar test with the system at temperature near the low end
of the operating range, it could result in a false high blood sugar. Repeat the test
in warmer environment with a new test strip as soon as possible. For additional
information on possible limitations for accuracy on precision, please refer to your
test strip insert. In order to make the most accurate comparison to your laboratory
results, please follow a few basic guidelines:
Before going to the lab
• Do not eat for at least two hours before you test your blood.
• Perform a control solution test to make sure that the meter is working properly.
• Take your meter with you to the lab.
While at the lab
• Follow all instructions in this Instructions for Use for performing a blood sugar
test with your meter.
• Conduct your meter test within 30 minutes after lab test.
• Use only fresh capillary whole blood from the fingertip.
You may still experience a difference from the laboratory test results because
blood sugars can change very rapidly over a short period of time. This can be for a
variety of reasons such as exercise, medication, stress or loss of body fluids.
