27 wrz 2024 · For high-sensitivity cardiac troponin T (hs-cTnT), levels above 14 ng/l (nanograms per liter) are considered elevated and may indicate heart damage or a heart attack. For high-sensitivity troponin I (hs-TnI), the normal reference ranges are: ≤15 picograms per milliliter (pg/ml) for women. ≤20 pg/ml for men.
22 lis 2011 · These levels used to be considered indicative of myocardial necrosis. However, with high-sensitivity troponin assays, circulating cTnT or cTnI can be found in the plasma as a result of transient ischemic or inflammatory myocardial injury.
28 lis 2023 · Normal troponin levels range from 0–0.04 nanograms per milliliter (ng/ml). The three proteins are troponin C, troponin I, and troponin T. Troponin C binds calcium and transports troponin I so...
Troponin test result ranges. In healthy adults, the reference range (expected level) of troponin is very low or undetectable. When troponin levels are higher than the reference range that means damaged heart muscle cells are leaking troponin into your blood.
18 lis 2019 · When measured with older generation assays, elevated troponin levels can be detected 6-12 hours after onset of myocardial injury, peaking at about 24 hours, followed by a gradual decline...
28 mar 2022 · It has been shown that there is a variability of troponin levels even in healthy patients, men presenting a higher level than the women, a circadian variability, with their values being slightly higher in the morning in healthy patients, age related variability.
2 paź 2023 · Cardiac troponin I and T are specific and sensitive biomarkers of myocardial injury. They are the preferred serologic tests for the evaluation of patients with suspected acute myocardial infarction. (See "Use of creatine kinase to detect myocardial injury", section on 'Why troponin is preferred'.)
