Biomarkers are measurable indicators of what’s happening in your body. They can be found in blood, other body fluids, organs, and tissues, and can be used to track healthy processes, disease progression, or even responses to medication. When combined with other tests, biomarkers can also help doctors determine whether a person might have or be at risk of developing Alzheimer’s disease or a related dementia.
