Posted September 11, 20186 yr comment_74557 Hi, Is it OK if the LJ chart graph lies on mean consistently (ie without fluctuations) ? Regards
September 12, 20186 yr comment_74572 It sounds like your SD is set too low. Try recalculating it based on recent results. Scott
September 14, 20186 yr comment_74600 Agree - highly probably that the SD being used is not appropriate i.e. to large. Results should be distributed across the L-J chart, with approx. 1:20 results in the 2-3 SD space. Suggest review local and published SD for analytes
September 18, 20186 yr comment_74629 Are you saying that a specific parameter is consistently the same exact value each and every time QC is performed and for all three levels? That would be amazing. There are a couple non reportable items on our analyzer that stay pretty consistent but they are items that have to do with the operation of the instrument such as diff X and Diff Y. none of our reportable parameters are steadily the same number each time...
