In that scenario, I think I'd be leaning towards the blood reading (unless that one seems way off).

I would love to see an image of your log - do you have a picture online anywhere? If not, are you willing to share?

I would be willing to share, Scott, but I'm not quite sure the easiest way to do this.
Please advise.

Yeah, I'm not sure of the best way either. Maybe even just snapping a picture of what you use and posting it? Don't spend too much energy on it, it's just a curiosity thing.

Okay Scott, I'll get my granddaughter to help me with this. We are going away for 10 days beginning tomorrow.
I'll get at this after I return.
Sorry

Hi, I am new to DEX, 1 week. So far so good. Type 1 45 years. I also would love to see this log. I put all the numbers in my log book and it gets to the point I can't read anything.

Given my writing looks like cluster of turkeys heading over the horizon plus I am messy; I rely on automation to store/list BG readings and find that better.

I also run handwriiten log for food, insulin doses, walks and caveman readings ( but that caveman numbers is on line as well with log printouts.

For caveman machine I use a Nova Max Biomedicals software package on PC.

Best wishes and good luck.

Thanks for you info. I am assuming you use a smart phone or something like that. Regretfully, I am really behind the times and do not even have a cell phone!
I think I will try to just put a log together myself.
I have seen your posts on other topics and I always get a giggle from your responses.

I always use the meter reading, too. That's what both CGM manufacturers recommend. And then, I remember that diabetes control, considering the tools we have to work with, is an art, not a science. Which is not to say that it's not a lot better than it was when YOU were diagnosed, but it's still lacking compared to what it COULD be.

Keep up the good work! :-)

It sounds like you have a great system that works for you. I would use the reading from the glucometer to calculate insulin needs.

What you describe is what I and probably Dexcom would expect. The CGM reading is an estimate of you BG levels based on your instatial fluid and it is approximately 20 minutes behind your finger stick levels. I do not know exactly what happens when you calibrate, however I would expect that the reading you see after calibration is calculated to where you would have been about 20 minutes prior to calibration. If you call tech support at Dexcom, they could probably give you a better explanation.

I always take a reading from caveman machine on each hand - bets finger on each and average that and use for insulin dosing as well as calibration entry.

I would have made many mistakes if I trusted the dexcom reading (on my arm)when dosing insulin.

Unfortunately, fingetips are always the most accurate and track the fastest BG activity of body on caveman machine. One would hope expensive gear and sensor would have best/fastest response but not so. Interstitial tissue readings are delayed as well as filtered/averaged thru interstitial tissue along with dexcom software.

I can track my liver's nasty dumps up to peaks on caveman and test strips but dexcom does not have frequency response to really follow. Stomack/intestine glucose release do not seem able to really ram the BG up fast on my body nor match the attack of the liver when it gets into act.

Otherwise, Brad dead on target from these quarters.
