May require adjusted cutoff for acceptable precision in clinical use; leaves open assay standardization needs.
The Immulite 2000 cTnI assay has a 99th percentile limit of 0.32 μg/L, but its precision at low concentrations is unsatisfactory, necessitating a cutoff of 0.4 μg/L for a CV of 12% in routine clinical practice.
Scharnhorst et al. (2002) studied this question.
