Troponin i normal range: Learn about troponin I

Learn about troponin I, a protein found in heart muscle that can indicate heart damage. Find out the normal and high levels of troponin I and other types of troponin tests. Troponin I test measures the levels of troponin I protein for detecting heart muscle damage, the procedure involved, and how to interpret the results. | Drlogy Troponin is a protein complex expressed in cardiac and skeletal muscle. The complex consists of troponin I (TnI), troponin C (TnC) and troponin T (TnT), which enable the interaction between actin and myosin and are therefore fundamental to muscle contraction. There are cardiac-specific isoforms of troponin and these are abbreviated cTnI, cTnT, and cTnC. The isoforms cTnI and cTnT are specific to cardiac muscle cells. Cardiac troponin levels are extremely low in healthy subjects; the 99 th ... In this article, we’ll explain everything you need to know about the troponin test: what it is, why it’s done, what normal ranges look like, and how to interpret the results.
