Troponin assays are not simply far more sensitive but may also be more certain than CK-MB assays. Expression of CK-MB is just not exclusive to the guts.37 CK-MB is present in skeletal muscle along with the gastrointestinal tract in addition to while in the uterus of pregnant Ladies.38 Furthermore, in patients with myopathies, the CK-MB content of skeletal muscle can increase markedly to up to fifty% of the whole amount of money for each gram of tissue.
