Biomarkers play an essential role in much disease detection. Much kind of biomarkers are available in the field of medical science with lots of positive as well as negative effect. Biomarkers will become one of the major driving forces of pharmaceutical research and drug development in the coming years. A specific and ideal biomarker for many unbeaten disease like cancer is still a big challenge.
