|Description||Troponin I (high sensitivity) is a cardiomyocyte-specific protein used in the detection of cardiac damage and associated risk assessment.|
|Indication||Suspected Acute Coronary Syndrome (ACS)|
|Additional Info||The high-sensitivity assay is capable of detecting lower concentrations of Troponin I and, in patients with suspected low-risk ACS, can be used as a rule-out test (use in conjunction with ED pathway).
hs-TnI should NOT be measured in Primary Care - if a patient is suspected of having ACS/MI, they should be referred to Secondary Care immediately.|
|Interpretation||Baseline hs-TnI <10 ng/L - rule out ACS.
Results >10 ng/L require a further test (after at least 3 hours) and should be interpreted according to the "Suspected Low Risk ACS Emergency Department Pathway".|
|Collection Conditions||Samples must arrive in the laboratory within 2 hours of venepuncture.
hs-TnI can only be added to a sample within 4 hours of venepuncture.|
