Biomarker

A bio-marker, or biological marker is a measurable indicator of some biological state or condition.

Biomarkers are used in many scientific fields.In medicine, a biomarker is a measurable indicator of the severity or presence of some disease state. 

Biomarkers used for medicine, or precision medicine, are a part of a relatively new clinical toolset. They are categorized in 3 primary ways according to their clinical applications. They are classified as molecular biomarkers, cellular biomarkers or imaging biomarkers. All 3 types of biomarkers have a clinical role in narrowing or guiding treatment decisions and follow a sub-categorization of being either predictive, prognostic, or diagnostic.
