Weight Loss Forum / Low Carb / March 2004testing error margin? or very fast spike/fall?
I know I have fast spikes and falls, but this is ridiculous. A fall of 24 points in 3 minutes? What's the margin for error on these strips? During morning spike before breakfast: 106 After breakfast: BG 103 mt 8.35 starting to drift? pleasantly eyes relaxing BG 129 mt 8.45 drifting way down, getting more 'sleepy'!!! BG 105 mt 8.48 leveling off????, getting clearer? Using TheraSense Freestyle, all three samples drawn close together on wrist. The 129 didn't make sense, so I repeated the test and got the 105. Skinny -- pre-diab hypo The margin of error on my recent strips was 5%. Did you perhaps stick yourself on a finger that had something sugary on it? Did you not get a full drop of blood? Did you get water from washing your hands mixed with the blood? All these can make a difference. -- Jenny - Low Carbing for 4 years. At goal for weight. Type 2 diabetes, hba1c 5.2.

I found out right away when I started checking my BG that even if I tested only minutes apart, I got different readings if I didn't change the lancet. Guess sugars or other impurities on the skin from the first use can affect the readings.

I have used the same lancet many times when comparing my two meters and have gotten results that were almost identical within the range of accuracy of the meter (which is not any 20% no matter how often you read that here.) I have also done two tests close to each other and seen reasonable results. I find new lancets are much more painful than old, for some reason. The dull ones don't hurt, the sharp ones do. Many people on asd report using the same lancets for a month or more without trouble. -- Jenny - Low Carbing for 4 years. At goal for weight. Type 2 diabetes, hba1c 5.2.

Putting in a new lancet adds a long delay and fumble finger factor fffubbffffbbbubbffflllllle.... :-) However wiping the installed lancet on the alcohol swab is easy, so I'll start doing that. /snip/ >I have used the same lancet many times when comparing my two meters and have >gotten results that were almost identical within the range of accuracy of >the meter (which is not any 20% no matter how often you read that here.) Hm?? What I meant to say was, can a bad strip or something account for a reading 20 points above the group of readings? Or does BG really spike and come down that fast? > I >have also done two tests close to each other and seen reasonable results. > >I find new lancets are much more painful than old, for some reason. The dull >ones don't hurt, the sharp ones do. Even the old ones sometimes hurt. I think it's whether they hit a nerve or something. I notice places on my arm always seem to sting, sort of in a line from elbow to wrist, as tho a nerve pathway ran along there. Skinny -- pre-diab hypo Ok, maybe I hadn't changed the lancet or swabbed properly. But the previous and following samples were all pretty close together on the wrist. Is a drop of 8 points a minute even possible? Without extreme sensations? Skinny -- pre-diab hypo --------------------------- >| I know I have fast spikes and falls, but this is ridiculous.

Signature370/300/270 Single malt scotch is awesome (NO it does NOT have carbs as DON'T vodka, gin, rum, bourbon, etc generally) Malt can be made low carb through the judicious use of yeast. Low carb beer? Uh...yeah. Read the books. You can have more than eggs for breakfast. Yes calories do count. Ketosticks are not neccessary to lose weight. Email: Actually my feet are big not medium. |
