Testing for Blood Sugar

the LPN's here seem to think that when taking a test for b/g the faster you can get the strip out of the blood spot the more accurate it is.  which is contrary to how it actually works.  I had mine tested today as usual and got a reading of 156 with his meter which usually measures 10 to 30 lower than the Prime meter I use.  I came back up and and used the prime and got a 120 or so.  I watched him as usual and he had the strip out very fast and I suspected it was innacurate.  Doctors depend upon these readings to medicate you.  Whata bunch of dunces.
