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 today are used for diagnosis and disease detection, but capable of so much more. They can tell us when drugs are effective and safe, and when and for whom a precise therapy should be started.
