Notes |
Units: results are reported as ng/L.
Reference range for high-sensitivity Troponin T(hsTnT) is <14ng/L
hsTnT can be within the normal range for up to 6 hr post acute MI
If hsTnT ≤ 14ng/L consider retesting in 6-12 hours to rule out MI
hsTnT >14ng/L is indicative of myocardial injury, however elevated hsTnT may occur due to non-ischaemic myocardial injury.
If hsTNT >14ng/L consider retesting in 6 hours
hsTnT > 53ng/L is highly indicative of myocardial injury
Consult hospital guidelines on the use of hsTnT in diagnosis of MI Haemolysis can produce a negative interference in the analysis of plasma Troponin T (HS), thus causing a potential underestimation of the actual result. Therefore please note that while a result for Troponin T (HS) will be reported in a moderately haemolysed sample, this may not represent the true value for that sample and the taking of a repeat sample for plasma Troponin T (HS) is strongly advised in order to facilitate the appropriate clinical management of patients. In addition, any Troponin T (HS) result ≤14 ng/L in a moderately haemolysed sample WILL NOT be reported at all due to the risk of underestimation.
