A troponin test measures the level of troponin in your blood. Troponin is a type of protein found in the muscles of your heart. Troponin isn’t normally found in the blood. When heart muscles become damaged, troponin is sent into the bloodstream. As heart damage increases, greater amounts of troponin are released in the blood.

SPECIMEN: 2 mL (1 mL min.) serum in 1 SST. Ship refrigerated or frozen.

STABILITY: Room: 8 hrs; Refrigerated: 72 hrs; Frozen: 4 weeks

REPORT: Daily

PRE-TEST INFORMATION: No special preparation required

USAGE: Troponin-I is a cardiac marker elevated only in patients suffering from acute Myocardial Infarction. Patients with renal disease or acute muscle injury show normal levels. High sensitivity assays can detect elevated levels of Troponin-I (above the 99th percentile of an apparently healthy reference population) within 3 hours after the onset of chest pain.
