Should Troponin Be Zero?

Raised troponin levels indicate cardiac muscle cell death as the enzyme is released into the blood upon injury to the heart. Normal levels of troponin should be zero and even small levels of detectable troponin indicate cardiac muscle cell death.

Is troponin 0.01 normal?

A normal troponin level is that within the normal reported reference range. So if the lab says < 0.04 is normal, then 0.03 and 0.02 and 0. o01 etc. are all normal!

What happens if there is no troponin?

Test results of your cardiac enzymes can indicate whether it's likely you had a heart attack. For example, most healthy, young people have no troponin T circulating in their bloodstream. The more damage the heart muscle has suffered during a heart attack, the higher the levels of troponin T circulating in your blood.
