Blood Tests and Insulin Injections
Question from New York, USA:
Is it true that there are different cutoff numbers for plasma calibrated meters and whole-blood calibrated meters?
On average, whole blood sugar levels read a little over 12% lower than plasma levels.
[Editor’s comment: Commercial laboratories usually report blood sugar levels in serum (which is essentially the same as plasma). So, if you wish to check your meter against a lab value, it is important to know whether that meter reads serum or plasma, or whole blood.
