WebA requirement to the cardiac troponin assays was that they should be able to measure levels of cardiac troponins at the 99th percentile with acceptable imprecision, which was set to ≤10 % CV (coefficient of variation). This requirement, however, was at the time met by very few assays and is still a major challenge to most current commercial assays. WebDifferent labs use slightly different normal ranges and results can vary depending on the type of troponin test done. For example, the normal range for troponin I is between 0 and 0.04 ng/mL but for high-sensitivity cardiac troponin (hs-cTn) normal values are below 14ng/L. Other types of heart injury may cause a rise in troponin levels. swiss olympic talent card fussball
