Is fasting required when comparing a blood glucose lab test result to a blood glucose meter result using an forearm sample?
As when comparing capillary fingertip results to a venous laboratory value, the sample collections should be performed at the same time when the patient is in a fasting state. When comparing results from the lab and a result using a sample obtained from the forearm on a blood glucose meter, it is best to have had no food in the last 4 hours.
