High-sensitivity troponin (hs-troponin) The definition of high-sensitivity assays is that it is able to detect troponin in healthy subjects without myocardial injury (i.e a few nanograms of troponin per liter blood).

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...
The high-sensitive troponin test is used to help doctors diagnose heart attacks and other potentially fatal heart conditions. Learn the meaning, procedure, diagnosis, complications, and prevention, as well as the normal range and high levels.
Nov 22, 2011 · What Is a High-Sensitivity Troponin Test? Rapid advances in immunoassay technologies and the international adoption of traceable troponin calibration standards have allowed manufacturers to develop and calibrate troponin assays with unprecedented analytic sensitivity and precision.

Jul 16, 2018 · High-sensitivity (hs) cardiac troponin (cTn) assays expedite the evaluation of patients with possible acute coronary syndromes (ACS) in the emergency department. Rapid screening protocols with hscTn have been proposed for patients for whom ruling-in or ruling-out acute myocardial infarction (AMI) is the primary issue.
Mar 1, 2021 · High-sensitivity cardiac troponin (hs-cTn) assays have the ability to detect minute troponin concentrations and resolve minor changes in biomarker concentrations.
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.
