[QUOTE="Squire Fulwood, post: 276940, member: 44622"] I think I have made a breakthrough with my SD Codefree meter. As I said in my earlier post it reads high when compared to my Freestyle which makes it difficult to discuss the results with my nurse because she lives on a different scale. I have persisted with the comparison between the two and recorded all the results. The next part of the plan was to enter the results of the SD onto a spreadsheet in diary format. There is an identical diary on the right hand side of the spreadsheet where the numbers are derived from the SD readings but multiplied by 0.885. This is a number derived by trial and error because I also entered the actual readings of the Freestyle in order to compare them with the SD derived ones and if they were different I tinkered. A couple of Freestyle readings are identical to the SD derived ones. Most of the rest are acceptably close and, of course, there is always the one that came from nowhere and just wrecks your stats. Also, I did the average of the derived readings. I used to do this when I only used the Freestyle. This is not the same as my Hba1c but gives me a warm feeling when the average is going down and gives me something to aim for. This average is very close to the sort of numbers I used to get with the Freestyle so I think I have made the SD usable, for me at least. Other people may have an SD with a different level of high reading. I am amazed how much work I am willing to put in just so I can use the cheaper test strips. One point to note. My SD can go completely out of whack at extreme ends of the scale so this technique might not be a good thing for anyone who is habitually hyper/hypo. [/QUOTE]
