I understood everything from your first post except the column "period"

I mentioned it. First digit is "meal", second digit is "hours since", do:

10 before breakfast
12 2 hours after breakfast
30 before dinner

etc.

Funny about the OneTouch and the Accu-Check. I had the opposite experience. I had used the OT for years and results seemed consistent and to make a lot of sense. I started side-by-side with the AC. Every result was 5 - 40 points higher, with a very rare exact match. The average difference was close to 30, always in the same direction. I didn't like the large sample size required anyway, so it stays in the drawer for now.

Then I got the Freestyle. It's also higher but only an overall average of 10 points and more so at lower numbers. But, one thing that seems to impact it is the strip touching the skin. It's not totally consistent yet, but if a make a bigger drop (in spite of the tiny amount required) and avoid touching the skin with the strip, the FS often reads much closer to the OT.

According to both meters, I apparently live basically my whole life between the 80s and the 130s. What the test shows is that in that context, my meter readings are worth basically nothing. Take some of my "10" (before breakfast) results 86 vs. 98!? That's all I wanted to know! Am I in the 80s or 90s? I'm never anywhere else, so what is the use of meters which can't answer my questions?

Thanks, moment of denseness on my part.

Thanks! Good to know - and I hadn't noticed that yet (although I had noticed it was a bit higher than my prior TrueResults meter.)

Interesting! I'm pretty sure I ALWAYS touch my skin when I take the blood... should I not be doing that? I just lower the strip into the bead of blood until it hits my skin, and the blood gets drawn up.

My original premise concerns calculating insulin units. Since you take no medications, a range within 80's or 90's is certainly sufficient. But I'm using my meter reading to calculate the number of units of insulin I should take. I was perfectly content to observe trends within ranges on the Relion meter prior to taking insulin. Now I would like to have as accurate a reading as possible.

Concerning meter use over the course of this test, I have begun wiping the first blood drop away, gathering a larger drop to test than normal (past history). Using this method I think the meters read much closer... I even had an identical reading on both meters. I'll post today's numbers sometime tomorrow but I also had a very high fasting number today of 170 on the Trueresult and 173 on the Relion... disturbingly high but amazingly close between meters!

I have used a OneTouch Ultra, Freestyle Lite and AccuCheck Compact. The OneTouch was middle of the pack reading-wise, and needed the most blood. The Freestyle Lite needed the least blood, but seemed to give much too low of results. Maybe I just had a bad one?

My current AccuCheck, reads higher than either and seems to be the most accurate. If I give it the bare minimum of blood, it reads lower than if I give it a big juicy drop. I try to use the same amount of blood each time to keep it consistent.

Steve, I am not sure what the answer is with regards to matching your insulin dose to your meter readings. I think if you don't want to drive yourself crazy, stick to one meter, and unless the number seems wildly wrong (in which case retest), just work with the number given.

Thanks! That sounds worth trying and may relate to how my Freestyle seemed to read even higher if the strip touched my skin.

This is the method the nurses used when they checked my sugar in the hospital last fall.
