Hi ,

I realize that, but if you look at the chart for whole blood there is a

difference.

If I have an A1c of 5.5 using the chart for comparison

plasma blood = an average of 118 bg readings

whole blood = an average of 105 bg readings

I am not starting an argument, but here is the statement from my handbook

that came with the Accu Chek Compact plus meter that I am now using. It is the

same statement that was with the Accu chek Compact meter that I was using.

" Your new blood glucose system is designed and approved for testing fresh

capillary whole blood samples. "

I no long have the handbook that came with my Ultra Touch meters but that

was " plasma blood " . The excel program that I use was based on plasma because I

was using the One Touch meters at that time.

One of the first things I learned when I joined this group was to read the

handbook to see which - plasma or whole blood - my meter tested.

This is the same chart you have listed before in previous posts.

Hi ,

Whenever I've listed this chart, I always list the second chart. Years ago,

all meters tested in whole blood, then most of them changed to plasma. Only

recently have some manufacturers gone back to whole blood.

Here is the statement that is at the bottom of the chart.

FWIW - Accucheck meters are Plasma based readings - that, as I recall, is

The One Touch Ultrasmart or others from this company are also plasma

based.

Here's how I understand it: The A1c chart for corresponding bg doesn't have

anything to do with your home meter, whether it be plasma or whole blood, which

may vary considerably within an acceptable range. It's not telling you what

your glucose meter averages should be; it's telling you you what laboratory

values the A1c numbers relate to. So, it doesn't matter what kind of meter you

are using -- your testing number has nothing to do with the chart.Maybe I'm

missing something in this discussion?

Eunice: No arguments - sharing information is what this list is about! I

gave that information based upon the book that came with my meter. ;OD I

was pleased, as that is a best-reference to reach a reasonable A1C

comparison.

I seem to recall that it was a calibration issue - naturally, they're

testing whole capillary blood.

Checking our little manuals is a good thing.

As I understand it, A1C results are plasma based results. Meters, in

general, test whole blood (capillary) samples. SOME meters are calibrated

to give a close approximation of plasma results. If that is the case, then

you meter readings can give you a good idea of about where your A1C results

will fall. In the case of my meter, they are nearly identical. The HbA1C

gives the average glucose (glycosated hemoglobin) over the course of the

last twelve or so weeks.

Testing SHOULD have some relation to your A1C's - how else would we have any

hope of knowing WHERE our numbers are and should be??

Just weighing in here..

That was exactly what I was trying to convey. The discussion was

relating to A1C and new A1C measurements and comparison to each other,

not what home meters say. You didn't miss anything.

What happened is the subject line was changed to " comparison charts

whole blood vs plasma " . The original subject line was: " blog with

highlights from ADA 66th Scientific Sessions " . In this case we were

still discussing the same subject but there was no reference for the

original discussion.
