A biomarker, or biological marker, usually refers to a measured characteristic which may be utilised as an indicator of some biological state. A biomarker can be a matter that is introduced into an organism as a means to analyze organ function or other aspects of wellbeing. For example, rubidium chloride is utilized as a radioactive isotope to assess perfusion of heart sinew. It can also be a matter whose detection shows a particular disease state, for demonstration, the occurrence of an antibody may show contamination. More specifically, a biomarker shows a change in state of a protein that correlates with the risk or progression of a disease, or with the susceptibility of the infection to a granted remedy. Biomarkers are characteristic biological properties that can be detected and assessed in components of the body like the body-fluid or tissue. They may indicate either normal or diseased methods in the body. Biomarkers can be exact units, molecules, or genes, gene products, enzymes, or hormones. Convoluted organ purposes or general characteristic changes in biological organisations can furthermore serve as biomarkers. Biomarkers can be classified on different parameters. They can be classified founded on their characteristics such as imaging biomarkers (CT, PET, MRI) or molecular biomarkers.
