Diagnostic tests and the biological markers (biomarkers) they measure are often classified based on the circumstances under which they are used. Biomarkers provide information about a patient at virtually every stage of care. They can help doctors evaluate the likelihood that a patient will develop a disease, diagnose a disorder, evaluate the severity of a disorder and/or its likely progression, determine optimal treatment strategies and monitor response to treatment.
Biomarkers can be classified into the following categories. Use the links provided to explore each in more detail.
