Analytic Comparisons of Contemporary High‐Sensitivity Cardiac Troponin Assays^*

	Limit of Detection (ng/L)	99% (CV) (ng/L)	10% CV (ng/L)
Hs‐cTn‐T
Roche Elecsys	5.0	14 (13%)	13
Hs‐cTn‐I
Abbot ARCHITECT	1.2	16 (5.6%)	3.0
Beckman ACCESS	2 to 3	8.6 (10%)	8.6
Mitsubishi Pathfast	8.0	29 (5%)	14
Nanosphere	0.2	2.8 (9.5%)	0.5
Radiometer AQT90	9.5	23 (17.7%)	39
Singulex Erenna	0.09	10.1 (9.0%)	0.88
Siemens Vista	0.5	9 (5.0%)	3
Siemens Centaur	6.0	40 (10%)	30

CV indicates coefficient of variance; Hs‐cTn‐T, high‐sensitivity cardiac troponin T; Hs‐cTn‐I, high‐sensitivity cardiac troponin I.

^*Typical units for troponin and hs Tn assays are μg/L.
