Overview
Troponin I Normal value range
Pathophysiology
Special considerations
Elevations in lab values
Nursing Points General
Normal value range Typically less than 0.035 ng/mL or less
Can vary among institutions
Has to be greater than the 99th percentile
Pathophysiology Troponin is released during myocardial cell damage
Decreased perfusion causes myocardial cell damage
Causes of myocardial cell damage Myocardial infarction
Demand ischemia
Cardiogenic ACS
Noncardiogenic Sepsis
Renal failure
Extreme exercise
