Biomarkers are playing increasingly important roles, and one disease area, cancer, is getting much attention in this regard. Technologies such as DNA microarrays are being used to analyze biological samples in molecular diagnostics to identify high-risk patients, predict response to therapy, and monitor patients during treatment to either determine effectiveness of treatment or detect recurrence of disease. Numerous companies are developing molecular oncology diagnostics tests.
In 2012, the global DNA diagnostics market was valued at more than $17.3 billion. The total market is projected to grow at a compound annual growth rate (CAGR) of 12.6% from 2013 through 2018 to reach nearly $36.5 billion by 2018.
