Overview
The Troponin I Test (High Sensitivity) is a blood test used to detect levels of troponin I, a protein released when the heart muscle is damaged.
This test is particularly valuable in diagnosing acute coronary syndromes (ACS), including myocardial infarction (heart attack).
Description of Troponin I Test (High Sensitivity)
- Methodology: The hsTnI assay employs a two-site immunoenzymatic (sandwich) method. Monoclonal antibodies specific to cardiac troponin I are used to capture and quantify the troponin in the blood sample.
- Sensitivity: This high-sensitivity test can detect very low levels of troponin, making it more effective than traditional assays in identifying heart damage.
Indications for Testing
- Acute Coronary Syndrome: The hsTnI test is primarily indicated for patients with suspected ACS, particularly those presenting with chest pain or other symptoms suggestive of a heart attack.
- Risk Stratification: It can also be used to assess the risk of future cardiac events in patients without acute symptoms.
Reference Values
- Normal Range: The 99th percentile for hsTnI is typically around 47 ng/L, but this can vary based on the specific assay used and the population studied.
- Interpretation:
- Levels below the normal range suggest no significant heart muscle damage.
- Elevated levels indicate potential myocardial injury, with higher values correlating with an increased likelihood of acute myocardial infarction.
Patient Preparation
- No specific preparation is required prior to testing. However, it is important that the blood sample is drawn at appropriate times, particularly in relation to symptoms and treatment.
Specimen
Serum, Hepranized, 3-5ml
Turnaround Time
Results from the hsTnI test are often available within 1 hour, allowing for rapid clinical decision-making.
