No cardiac certain isoforms are noted for human TnC.
A Look at of troponin levels is done with a blood draw that checks how much from the protein troponin is circulating within the blood. Greater than 0.04 nanograms per milliliter (ng/ml) can indicate coronary heart problems. The looking at may well range, however, dependant upon the style of examination getting completed.
