Troponin i normal range: 2 mL (1 mL

2 mL (1 mL min.) Serum in 1 SST. Ship refrigerated or frozen. Normal Values: The normal range for Troponin I levels may vary slightly depending on the laboratory that performs the test and the specific assay used. Source 1 Troponin-I = < 0.03 mg/mL Source 2 Troponin-I = <3.1 µg/L Source 3 Troponin I = <0.35 ng/mL Or <0.35 µg/L Interpreting ... 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 ... Learn what troponin is, how it relates to heart health, and what the normal and high ranges of troponin levels are.
