Comparison Of Your Meter And Laboratory Results; Before Going To The Lab; While At The Lab - Advocate Redi-Code+ BMB-EA001 User Manual

Comparison of
Your Meter and
Laboratory Results
Test results with this meter are plasma-calibrated.
Since the laboratory tests provide plasma-calibrated
results, your meter may differ from your laboratory result
due to normal variation. Meter results can be affected by factors
and conditions that do not affect laboratory results in the same way.
To obtain an accurate comparison between meter and laboratory
results, follow a few basic guidelines below.

Before going to the lab

▪ Perform a control solution test to make sure that the meter is
working properly.
▪ Fast for at least eight hours before you perform your blood test.
▪ Take your meter with you to the lab.

While at the lab

▪ Only use fresh capillary blood obtained from the fingertip.
▪ Collect your blood into heparin-containing test tubes and do NOT
use other anticoagulants or preservatives.
▪ Conduct your meter test within 15 minutes of the lab test.
You may still have a variation from the result because blood glucose levels can change in some specific
situations that could cause a difference of more than ±20%.
▪ You have eaten recently. The blood glucose level from a fingertip can be up to 70 mg/dL higher
than blood drawn from a vein (venous sample) used for a lab test *7 .
▪ If your hematocrit (the amount of red blood cells in the blood) is high or low.
▪ You are suffering from severe dehydration (the loss of body fluid).
You may see the package insert of test strip for accuracy and precision data and for important information on
limitations.
