Long Term Stability: The difference between initial concentration and after 7, 14 and 21 days did not show any significant difference while slight difference in concentration after 28th day was observed which is within the acceptance limit ([greater than or equal to] 15%) of accuracy and precision (Table-8).
In the first case, the acceptance limits are defined by the inherent analytical imprecisions, and in the latter case the acceptance limits are defined by the analytical quality specifications.
The agreement was first determined graphically with a scatterplot produced with the reference method (Cobas) as the x-axis, the compared method (CardioChek) as the j-axis, cholesterol values, equality line, acceptance limits around the equality line, clinical allowable error limits around the equality line, and Passing-Ba-block regression line (Fig 1).
