2022年3月17日 · This test involves taking a sample of your blood, analyzing it and determining if there's any troponin in the sample. If the troponin level is high enough, it's a clear indicator of heart damage. This test, combined with other diagnostic tests and methods, is a key tool to diagnose a heart attack.

Troponin T (cTnT) and troponin I (cTnI) increase 2-3 hours after the onset of acute myocardial infarction. The maximum troponin value is observed in 12–48 hours. Troponin may be elevated for up to 2 weeks after a heart attack. The larger the infarction, the higher the troponin level and the longer the duration of elevated troponin levels.

2024年9月27日 · The high-sensitivity cardiac troponin test (hs-cTnT) is the latest generation of the cardiac enzyme testing that allows for detection of very low levels of troponin T, helping to diagnose heart attacks more quickly. If the test is negative, it can also help “rule out” heart damage from coronary artery disease (CAD).

Other names: cardiac troponin I (cTnI), cardiac troponin T (cTnT), cardiac troponin (cTn), cardiac-specific troponin I and troponin T. What is it used for? A troponin test is mainly used to: Confirm if a person is having a heart attack or recently had a heart attack. This is the most common reason for troponin testing.

The high sensitive troponin I test is a chemiluminescence microparticle immunoassay, which is used to quantitatively determine cardiac troponin I in human plasma and serum.

2011年11月22日 · Assays for cTn, namely cTnI and cardiac troponin T (cTnT), are the preferred diagnostic tests for ACS, in particular non–ST-segment–elevation myocardial infarction, because of the tissue-specific expression of cTnI and cTnT in the myocardium. The results of cTn testing often guide the decision for coronary intervention.

The i-STAT System test for cardiac troponin-I (cTnI) measures cardiac troponin-I amount-of-substance concentration in plasma or the plasma fraction of whole blood (dimension ng mL-1) for in vitro diagnostic use. Cardiac troponin-I values assigned to i-STAT’s controls and calibration verification materials are

High-sensitivity cardiac troponin is a newer type of testing that can detect lower levels of troponin. This may help diagnose heart injury and acute coronary syndrome earlier. Your healthcare provider will explain which type of troponin testing was done and what the results mean for you. How is this test done?

The i-STAT cardiac troponin I (cTnI) test is an in vitro diagnostic test for the quantitative measurement of cardiac troponin I (cTnI) in whole blood or plasma. Measurements of cardiac troponin I are used in the diagnosis and treatment of myocardial infarction and as an aid in the risk stratification of patients with acute coronary syndromes ...

心肌肌钙蛋白(Cardiac troponin I，CTnI)是心脏特异表达的调控蛋白，通过抑制肌球蛋白和 Actin的结合，介导横纹肌松弛，在心脏的收缩中发挥关键作用。TnI-心肌为TnI亚家族三个基因之一。
