The magnitude of the concentration change that best discriminates between acute and chronic increases has not been defined yet, and it is still a matter of debate whether one should prefer relative changes, absolute changes, or the reference change value, a metric calculated from short-term or intermediate-term biological variation in cardiac troponin.
To assess the significance of the difference between 2 serial data points, the percent difference between 2 serial points is compared to the critical difference, or reference change value (RCV).
Reference change values (RCVs) were calculated as previously described (4) according to the method of Fokkema et al.
Recent publications have reported both shortand long-term reference change values (RCVs) in healthy populations for both high-sensitivity cardiac troponin I (hs-cTnI) and high-sensitivitycardiac troponin T (hs-cTnT); thus, the RCV perhaps could be the metric used for determining the optimal clinical change value (2, 3).
The use of data from studies of biological variation permits calculation of the reference change value (RCV): RCV = z X [square root of (2)] X ([square root of ([CV.
BACKGROUND: High-sensitivity cardiac troponin assays will augment the frequency of increased results, making important the determination of reference change values to distinguish acute from chronic increases.
It is unclear whether one should rely on a reference change value based on analytical and biological variability or clinical optimization.
