Dear Colleagues, I have some questions regarding the implementation of delta checks (DC) for endocrine tests. Which criteria did you use to calculate the delta check value for each analyte? Did you calculate the DC using analytical and biological variation for each analyte? How did you decide on the look back time interval for each analyte? Any other information which you are able to provide will be greatly appreciated.
