What are the normal and high values of Troponin T (Trop T) levels, and how do they help differentiate between no heart attack, a minor heart attack, and a major heart attack?
Normal Troponin T (Trop T) levels are typically below 15 ng/L in males and below 14 ng/L in females, which indicates no heart attack or heart muscle damage. Values in the range of approximately 14–52 ng/L may suggest a minor heart attack or mild myocardial injury. Values above 52 ng/L are typically associated with a major heart attack and significant heart muscle damage. However, doctors also assess symptoms and repeat Troponin measurements to confirm the diagnosis.
