Hi Jenny,

I was reading an article on your website tonight regarding plasma vs
wholeblood calibrated meters. I use a relion ultima. According to
your article the older relions used the whole blood calibration which
equated to a reading that would be 12% lower than a plasma reading.
Did I understand that correctly? So, if I had a reading of 140 the
reading would equate to 156? To your knowledge, is this the case with
the newer Relion Ultima? I

I am pretty sure that the Relion Ultima is plasma calibrated. In fact, I don't know that there are any meters on sale in the U.S. now that are not. So don't worry about it. The Relion meter that was blood calibrated was a flat rectangular meter.

Blood calibrated meters were still being sold when I posted the web page a couple years ago and there are still people who should know better using them, who don't know about the conversion. In fact, I ran into two nurses, one at my doctor's office and one a Town Nurse who were still using old whole blood calibrated meters as recently as this past September. Neither realized their readings would differ from a lab reading.

But anyone who has bought a new meter in the past year or two has a plasma calibrated one.
