ID:986 Troponin I (high-sensitivity)
Search Links: General Info : Protocols : LabTestsOnline

DescriptionTroponin I (high sensitivity) is a cardiomyocyte-specific protein used in the detection of cardiac damage and associated risk assessment.
IndicationSuspected Acute Coronary Syndrome (ACS)
Additional InfoThe 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.
Concurrent Testsna
Dietary Requirementsna
InterpretationBaseline 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".

SampleVenous Blood
TubeSerum Gel

Collection ConditionsSamples must arrive in the laboratory within 2 hours of venepuncture. hs-TnI can only be added to a sample within 4 hours of venepuncture.
