WebJan 1, 2024 · The LoB is the highest cardiac troponin concentration expected to be found when replicates of a sample containing the zero calibrator for a cardiac troponin assay are tested. Statistically, it is often represented as: LoB = mean (zero calibrator) + 1.645 × SD (zero calibrator). WebAug 8, 2024 · Cardiac troponin is currently the first-line test for evaluating patients with suspected acute MI. Troponin is a protein found in both cardiac and skeletal muscles that play a role in muscle contraction. It is comprised up of three subunits, troponin C, troponin I and troponin T. Troponin I and troponin T in the heart are structurally different ...
