New troponin assay
Witryna1 lip 2024 · In the early 1990s, assays were developed to quantify the level of cardiac troponin (cTn) in the blood. Early testing quickly proved that the presence of cardiac troponin indicated cardiac injury had occurred. Since then, rapid measurement of cardiac troponin has become a crucial step in the early diagnosis of acute coronary … Witryna10 maj 2016 · Another group devised a signal quenching system by coupling quantum dot and graphene, each of which was ...
