A biologic feature that can be used to measure the presence or progress of disease or the effects of treatment. For example, prostate specific antigen (PSA) is a biomarker for cancer of the prostate.

A biological molecule found in blood, other body fluids, or tissues that can be used to follow body processes and diseases in humans and animals.For more information, see biomarkers.

A substance produced by the body, often detectable in body fluids such as blood or urine, that indicates a specific process, condition or disease

Objective measurements that indicate a patient’s health status, such as tests of muscle strength, a blood test, imaging, etc. Diagnostic biomarkers show if a person has a disease. Therapeutic biomarkers show if a therapy is having the desired effect.

A biological molecule found in blood, other body fluids, or tissues that is a sign of a normal or abnormal process, or of a condition or disease. A biomarker may be used to see how well the body responds to a treatment for a disease or condition. Also called molecular marker and signature molecule.

observable change (not necessarily pathological) in the function of an organism, related to a specific exposure or event.

A distinctive biological indicator of an event, process, or condition.

A substance sometimes found in the blood, other body fluids, or tissues. A high level of biomarker may mean that a certain type of cancer is in the body. Examples of biomarkers include CA 125 (ovarian [..]

A molecular indicator of a specific biological property; a biochemical feature or facet that can be used to measure the progress of disease or the effects of treatment.

a physical, functional, or biochemical indicator of a physiological or disease process.

A molecule or substance in the body that is used as an indicator of a specific biological process occurring in the body. The most common use is to find indications of disease. For example, the presenc [..]

A biological molecule found in blood, other body fluids, or tissues that is a sign of a normal or abnormal process, or of a condition or disease. A biomarker may be used to see how well the body responds to a treatment for a disease or condition. Also called molecular marker and signature molecule.

An indicator, usually of a disease or a risk for a disease. For example, blood cholesterol is a biomarker for a risk for heart disease.

a protein whose presence or level of expression is an indicator of a cellular process.

A molecular marker associated with a biological function.

A biological marker is an indicator of a biological state. It is a characteristic that is measured and evaluated as an indicator of normal biological or pathogenic processes. Biomarkers are used to indicate an exposure to chemicals in the environment by an organism.

Biomarkers (short for biological markers) are biological measures of a biological state. By definition, a biomarker is “a characteristic that is objectively measured and evaluated as an indicator of normal biological processes, pathogenic processes or pharmacological responses to a therapeutic intervention.”

A variation in cellular or biochemical components or processes, structures, or functions that is objectively measurable in a biological system and that characterizes normal biologic processes, pathogenic processes, an organism's state of health or disease, likelihood of developing a disease, prognosis, or response to a particular therapeutic i [..]

A cellular, biochemical, or molecular indicator of a particular biological condition or process. These indicators can be measured accurately, and are often characterized as biomarkers of exposure, effect, or susceptibility.
