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?  If so,  I'm not doing as well as I thought.
Or did I misinterpret your article?

Thanks.  I'm sure a lot of relion users would be interested in this
piece of information.

My Ultima strips info indicate they're calibrated for plasma.

Thank you.  I had apparently thrown out the insert from my recent box
of strips.

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.

Thanks to Jenny & Uncle E.

I did write a note to the Relion Folks.  Apparently they have not
updated the information provided to their P/R people as this was my
reply:

Laura,
Thank you for contacting ReliOn® Customer Service.  ReliOn® Ultima is
calibrated for whole blood.  As far as the variance, please contact
our manufacturer directly at 800.992.3612 for this question.  Please
let us know if we can be of further assistance.

Thanks for your support,
ReliOn® Customer Service

I purchased a new box tonight and after deciphering the information
for physicians, I gathered that they calibrate on plasma using the
1.12 x whole blood to get the plasma number.

Very frustrating.  I am thinking of getting another meter for periodic
double checks.  Since my fasting numbers never rate a second glance, I
can't get a prescription, so this is out of pocket, and those other
brands are incredible in price.

We appear to live in a world that punishes proactive patients.  When I
quit smoking a few years back, when nicotine patches and gum were
still prescription, my doc had to fudge the diagnosis for zyban by
calling it treatment for depression (which was part of the package, so
it wasn't completely untrue) and ordering generic welbutrin.  Worked
well enough, though I had to abandon the med after a month because of
heart racing (which I now think was hyperthyroid).  Fortunately, it
had done the trick.

I guess somehow in thier infinite wisdom, the insurers prefer to pay
for the after affects of disease, rather than promote prevention.

Tell me about it. I had to pay for all my testing supplied for several
years after discovering I was diabetic because Kaiser took one look at
my "normal" fasting blood sugar (under 110 mg/dl) and wouldn't pay for
supplies. Eventually they went out of business in my region, I got a new
doctor, and prescriptions for strips.

When I first started buying strips there were no drug store brands so
they were all obscenely expensive. When the Relion and drug store brands
came out I used them. The Relion was more consistent than the Truetrack
back then. Now the Truetrack looks pretty reasonable to me. Their strips
are about $50/100 (though that might have been on a periodic sale).
