Serum biomarker

Serum biomarkers are substances found in blood that can indicate the presence or state of a disease, condition, or physiological process. They often include proteins, hormones, or other molecules released into the bloodstream by organs or tissues. Healthcare providers analyze these biomarkers through blood tests to help diagnose conditions, monitor disease progression, or evaluate treatment response. Because they are easily accessible via a simple blood draw, serum biomarkers are valuable tools for early detection and personalized medicine, offering insights into health status without invasive procedures.
