Blood Based Biomarker: A Promising Avenue for Non-Invasive Disease Diagnosis and Monitoring

Blood is one of the most accessible biofluids in the human body. It carries biological molecules that are released by organs, tissues and cells. These molecules can provide a wealth of information about physiological and pathological processes occurring inside the body. Researchers have long sought to identify and characterize biomarkers in the blood that can serve as signatures of disease. Successful identification of such biomarkers has the potential to transform medicine by enabling simple, inexpensive and non-invasive methods for disease diagnosis, prognosis, screening and monitoring treatment response.

What is blood based biomarker?

blood based biomarker refer to molecules found in blood samples that can act as indicators of normal biological or pathological processes, or as indicators of exposure to environmental agents including chemicals, drugs, or infectious agents
