Delta check methods for outpatients based on the CV of ADD and time dependency

^*The median CV% of the ADD (105.06%) and the median Pearson r between the ADD and the time difference between the paired test result (0.052) were used as the cut-off values for the determination of delta check methods for each test item; ^†The values that corresponded to 2.5% and 97.5% of the determined delta check method are presented as the lower and upper limits of delta check.

Abbreviations: ADD, absolute delta difference; ALP, alkaline phosphatase; T, total; BUN, blood urea nitrogen; D, direct; CK, creatine kinase; TIBC, total iron binding capacity; TG, triglyceride; Chol, cholesterol; DD, delta difference; DPC, delta percent change; RD, rate difference; RPC, rate percent change.
