Test Code (รหัสการทดสอบ):
TROPT

Order Name (ชื่อการทดสอบ):
Troponin T

 
Specimen / Container (สิ่งส่งตรวจ/ภาชนะ):
Blood/ Lithium heparin Blood (Green top) 6 mL, 1 tube
 
Turnaround Time (ระยะเวลารอผล):
Specimen collected to reported within 50 Mins.
 
Useful For (ประโยชน์การทดสอบ):
Determination of cardiac troponin T in human plasma.

Used as an aid in the differential diagnosis of acute coronary syndrome to identify necrosis, e.g. acute myocardial infarction. The test is further indicated for the risk stratification of patients presenting with acute coronary syndrome and for cardiac risk in patients with chronic renal failure.

Useful for the selection of more intensive therapy and intervention in patients with elevated levels of cardiac troponin T.

Clinical Information (ข้อมูลทางคลินิก):
Cardiac troponin T (cTnT) is an independent prognostic marker which can predict the near-, mid- and even long‑term outcome of patients with acute coronary syndrome (ACS).  Cardiac troponin has been reconfirmed as the preferred marker of myocardial injury in the new guidelines for the diagnosis and treatment of non‑ST‑segment elevation acute coronary syndromes.  Troponins are released during the process of myocyte necrosis. While they are cardiac specific, they are not specific of MI only. To distinguish between acute and chronic cTn elevations, the Universal Definition of AMI requires the need for serial sampling to observe a rise and/or fall of cTn above the 99th percentile upper reference limit. Absolute changes in cTn appear to
have a higher diagnostic accuracy for AMI compared to relative changes.Results interpretation have to be analyzed integrating the clinical assessment, including ischemic symptoms and electrocardiographic changes.   

Elevated levels of troponin T correlate with the severity of coronary artery disease and to poor outcome independent of natriuretic peptide (NT‑proBNP or BNP) levels.  Myocardial cell injury leading to elevated cTnT concentrations in the blood can also occur in other clinical conditions such as myocarditis,heart contusion, pulmonary embolism and drug‑induced cardiotoxicity.

Low concentrations of troponin T are an independent predictor of cardiovascular events including occurrence and recurrence of atrial fibrillation.
