Troponin can be a protein in coronary heart muscle that regulates coronary heart muscle mass contractions. A troponin examination is often a laboratory test that measures troponin ranges in blood. Higher troponin levels might suggest coronary heart damage.
Amplified troponin levels could be observed with a big pulmonary embolism, presumably owing to increased right heart pressure. [26] Elevated troponin degrees inside the setting of acute pulmonary embolism portends a even worse prognosis than in clients without the need of elevated troponin ranges. [27]

Serum or heparinized plasma would be the sample type for some commercially obtainable assays; whole blood is utilized for some point-of-care approaches.[30] Nonetheless, several scientific tests report major distinctions in cTnI measured in serum and plasma, with plasma effects reportedly currently being as many as about thirty% decreased when compared with serum.
