The high-sensitivity cardiac troponin test can detect very small levels of troponin T in the bloodstream. The normal range (value) for high-sensitivity cardiac troponin T test (hs-cTnT) is 14 ng/l.

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. Repeating this test is common because comparing you...
For the most part, heart attacks are unpredictable and that means you can’t prepare for this test. Important: If you need to undergo a troponin test, tell your doctor if you take Vitamin B7 (also known as biotin) and what dose you take. This vitamin can interfere with the results, and your doctor will need to know about this beforehand. Depending o...
This test involves a blood draw for a sample. A phlebotomistor other trained professional will insert an intravenous (IV) needle into a vein (usually a vein in your arm) and fill up one or more test tubes with blood. If you already have an IV line inserted into a vein, a provider may use that line to collect the blood sample.
Test results usually come back in one to two hours. Once they do, your healthcare provider will talk to you about your results and what they mean. Some people may need follow-up testing and additional medical care because of continuing symptoms or concerns, while others may be well enough to go home. Your provider can also tell you more about what ...
In most cases, there are minimal or no side effects from this test. In most cases, there is only a slight pinch or poke when inserting the needle to take the blood sample (unless an existing IV line is available to take the sample). You may develop a small bruise, especially if you bruise easily, but these usually go away within a few or several da...
Troponin I levels are substantially higher than troponin T levels in acute myocardial infarction. Troponin I levels may be up to 100 times higher than troponin T in the same individual. Hence, higher troponin levels should be expected when converting from troponin T to troponin I assays.
Nov 22, 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.

Jul 1, 2022 · A low score ( < 3) predicts 30-day MACE miss rate within a range of 0% to 2%. In adult patients with recurrent, low-risk chest pain for >3 hours duration, we suggest a single, high-sensitivity troponin below a validated threshold to reasonably exclude ACS within 30 days.
Dec 18, 2023 · High-Sensitivity Cardiac Troponin (hs-TnT) The normal levels of troponin in the blood are very low, usually around 0-0.04 nanograms per milliliter.

Oct 1, 2023 · With a minor heart attack, troponin levels can rise two to three times the upper limit of normal, but can go as high as 500 ng/L with a major heart attack. The values usually rise over a 24-hour period and then slowly fall over the following week.
