99th centile=the upper reference limit as determined in a healthy reference range population
| 99th centile (Diagnostic threshold) | 10% coefficient of variation* | Limit of detection | |
| Roche Elecsys high-sensitivity cardiac troponin T7 | 14 ng/L | 13 ng/L | 5 ng/L |
| Abbott ARCHITECTSTAT high-sensitivity cardiac troponin I8 | 16 ng/L (females) 34 ng/L (males) 26 ng/L (single threshold) | 4.7 ng/L | 2 ng/L |
Limit of detection,the lowest concentration which can be reliably distinguished from a sample with no troponin present.
*Lowest concentration where coefficient of variation is <10% (measure of dispersion of replicate sample results around the mean (SD/mean)).
