Cardiac Troponin Cardiac troponin T (cTnT) and troponin I (cTnI) are specific proteins released into the bloodstream following myocardial injury. These proteins play a critical role in regulating myocardial contraction. Normal values: 0-0.04 ng/mL High sensitivity cardiac troponin (hs-cTnT) assays have been developed to detect even small increases in troponin levels. Normal values are below 14 ng/mL Possible causes of elevated levels: Myocardial infarction Ischemia Stress Blood tests cannot detect non-ischemic causes. Even small increases in troponin levels can indicate damage across the heart. Cardiac Troponin Significantly raised troponin levels after a suspected acute coronary syndrome case are a strong indication of a recent heart attack. Measurement of cardiac troponin I is preferred within the first 12 hours after chest pain onset. It is essential to repeat measurement at a later time interval, either the next day or after a heart attack. Liver Diseases Liver cells contain several enzymes which can be released into the circulation in liver damage. Measurement of selected enzymes in serum is often used to assess liver function. There is no single enzyme that is completely specific for liver damage. Despite this, a combination of different tests can be used to assess liver function.
