From: Thelma Lubkin on 11 Oct 2005 19:25 My husband just noticed that he's gone through about 20 strips with his Freestyle blood glucose monitor code set to 17 when it should have been set to 12. He's not expecting to correct those readings with any precision, but does anyone know at least what direction the correction would go in, and better yet a back of the envelope algorithm for a reasonable guess? thanks, --thelma

This should be done with all meters, and as far as I know, it is not done for any. -- This address is for information only.

No, but why don't you find out yourself? Do threee tests at different times, each test with two strips, one set to code 17 and one to code 12. Either there is a pattern or there is not... and please tell us about your findings ;-) Anja

If I could convince him to explore this any further I wouldn't have posted. --thelma : Anja
