Hi Everyone. I have a BS in medical technology (lab), so I have your answer. As each laboratory buys any "machine" to run tests, the lab is required to run numerous random samples thru the machine, calculate the "average" and establish a range for that machine, in their lab, using their patient's blood. Therefore, each lab has a different set of normal values (an expected range) even if they are using the same brand of machine as a lab across town.
