One of the big ideas that emerged since the completion of the human genome project was molecular biomarkers. Scientists studying biomarkers associate them with human diseases and drug responses. Today, biomarkers are frequently used to target immunoassays for mark detection and quantitation of disease. Molecular biomarkers could be particular kinds of cells (I.e. CD4 cells in HIV), specific molecules, or...
Biomarkers are substances, structures, or processes that can be measured in biological samples such as urine, blood, or saliva. A biomarker is a measurable characteristic in a biological system that changes due to disease, exposure to chemicals, or exposure to organisms.
