Specific chemicals that occur naturally in the body, which can be used to monitor disease progress or effects of treatment. The biomarker used to monitor the progress of Paget’s disease is Serum Alkaline Phosphatase (SAP).
A cellular or molecular indicator of exposure, disease, or susceptibility to disease.
Substances in the blood whose levels can indicate the presence or extent of disease
Any of various biological or biochemical indicators that serve to detect exposures to carcinogenic processes or to predict carcinogenic disposition.
Measuring chemicals or their metabolites in biological materials (e.g., blood, urine, breath) to estimate exposure, or to detect biochemical changes in the exposed subject before or during the onset of adverse health effects. Sometimes refers to a specific indicator for a particular disease/functional disturbance.()
Biological changes that characterize the aging process; because biomarkers are considered a better measure of aging than chronological time, studies are underway to identify biomarkers in cells, tissues, and organs.
or biological markers, are molecular, biochemical, physiological changes that can be used as measures of susceptibility, as measures of exposure to dietary and environmental affects, as measures of ear]y pathological changes and as surrogates for screening and diagnosing disease.
a protein or compound easily detectable in the body that indicates an exposure has occurred.
Substances sometimes found in an increased amount in the blood, other body fluids, or tissues and that may suggest the presence of some types of cancer. Biomarkers include CA 125 (ovarian cancer), CA 15-3 (breast cancer), CEA (ovarian, lung, breast, pancreas, and GI tract cancers), and PSA (prostate cancer). Also called tumor markers.
