What does the term "biochemical markers" refer to?

The term "biochemical markers" refers to substances that can indicate physiological or pathological processes in the body. These markers can be found in various biological samples, such as blood, urine, or tissues, and their presence, absence, or concentration can provide valuable insights into a person's health status or disease processes.

For example, biochemical markers can be enzymes, hormones, metabolites, or other molecules that reflect normal biological functions or indicate the existence of disease. They are widely used in medical diagnostics and monitoring to help assess conditions such as heart disease, cancer, liver function, and many others. The ability of these markers to signify changes in the body makes them crucial tools in both clinical and research settings, facilitating early detection, diagnosis, and treatment monitoring.
