The word biomarker is short for biological markers. Biomarkers are measurable indicators of a biological process. Biomarkers can usually be measured through external testing such as tests of blood, urine or other body fluids such as cerebrospinal fluid (CSF) or can be measured by MRI scans or other physical tests.
Often the term biomarker is used to describe indicators that are observable during disease or a factor which may predict disease onset. Biomarkers may also be used during clinical trials to determine whether the treatment being tested is working.
Biomarkers are an important measure in MS as they can predict disability progression, monitor ongoing disease activity, and assess treatment response, all of which are integral in making important decisions regarding MS treatment.
