Guest guest Posted January 30, 2004 Report Share Posted January 30, 2004 HI , Did he happen to mention anything about whether these figures quoted are based on capillary (fingerprick) or vein readings? There is quite a big diff in the 2, because fingerprick (capillary) readings are 'diluted' with plasma etc, so I think these come out as about 30% lower reading wise than they would if a vein test instead. Hopkins originally used ketone meters that were already calibrated to allow for the difference bwteen the 2 diff methods of sampling (I emailed the author of one of their first papers on the bhb readings a couple of yrs ago) but I'm not sure whether that would still apply in this latest info Dr Freeman has supplied here??

Guest guest Posted January 30, 2004 Report Share Posted January 30, 2004 When your children have Venous blood work done-do 2 things !. do a finger stick and check results with the lab 2. Use the venous sample and then check the level on your machine Compare the results venous & capillary But you are also checking the venous in your monitor against the lab And seeing what the capillary is vs venous This will help you get the numbers to strive for during fine-tuning Sandi Quote Link to comment Share on other sites More sharing options...
