[IP] Freestyle Meter



Here is some data I have personally collected on this issue. The FastTake
data is taken using the new style FastDraw test strips

Date/Time                         FreeStyle     FastTake
11/07/2000 07:02:00 PM     200             222
11/02/2000 10:10:00 PM     357             382
11/01/2000 07:08:00 PM     313             298
11/01/2000 06:43:00 AM     203             200
10/31/2000 10:21:00 PM     292             328
10/31/2000 07:15:00 PM     364             372
10/31/2000 06:32:00 AM     73                 69
10/29/2000 12:36:00 PM     128             126

Regression Output (Independent=FastTake, Dependent=FreeStyle):

Constant                     10.3
Std Err of Y Est           16.6
R Squared                   0.9796
No. of Observations       8
Degrees of Freedom       6

X Coefficient(s)          0.9251
Std Err of Coef.          0.0546

The one thing I have noticed is that (as Lifescan warns) if the window of
the FastTake strip is not completely full then the reading will be low. This
was a real problem when I was taking samples from the top of my arm. All of
the above data is from generous size fingertip samples.

At this point I'm happy with either meter.
