Mainstream doctors don't as a rule use the cell tests.
Some holistic ones do however. There is pyridoxal in red blood cells and if they burst during handling of the sample, that is reading serum levels, then a false elevated result occurs. This also happens for potassium. Doctors know this and reorder another test if potassium results are high. The medical term for this is a "factitious elevation".
I really don't put much stock in B6 testing. It is only really valuable for extreme lows.
