Disease markers

Disease markers are specific substances or changes in the body that indicate the presence or progression of a disease. They can be molecules like proteins, genes, or chemicals measured through blood tests, tissue samples, or imaging. These markers help doctors detect, diagnose, and monitor diseases more accurately, and sometimes predict how a disease might develop. For example, certain markers are elevated in cancer or infections, guiding treatment decisions. Overall, disease markers are valuable tools that serve as indicators to understand and manage health conditions effectively.
