Comparing your meter and laboratory results
Test results with the OKRA Pro Blood Glucose Monitoring System are plasma-equiv-
alent. This method will help you and your Healthcare Professional compare your
meter results with laboratory test results. The OKRA Pro 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:
1. You are severely dehydrated.
2. 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.1
3. Your hematocrit is above 65% or below 20 %.

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:
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.
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.
