Abstract
The present disclosure relates to a test kit for detecting a concentration of a cardiovascular disease-related biomarker including a group selected from the group consisting of a first aptamer, a second aptamer and a third aptamer. The first aptamer has binding specificity to an N-terminal pro-brain natriuretic peptide (NT-proBNP). The second aptamer has binding specificity to a cardiac Troponin I (cTnI). The third aptamer has binding specificity to a fibrinogen.
