Types of biomarkers:

1. Diagnostic biomarkers: "identify the presence of disease at the earliest stage, before clinical manifestation. (Wilson et al., 2007)
2. Prognostic biomarkers "stratify risk of disease progression in patients undergoing definitive therapy." (Wilson et al., 2007)
3. Predictive biomarkers: identify patients most likely to respond to specific interventions." (Wilson et al., 2007)
4. Therapeutic biomarkers: "provide a quantifiable measure of response to therapy in patients undergoing treatment." (Wilson et al., 2007)
5. Toxicity biomarkers: "biomarkers can be used to identify patients at risk for developing adverse reactions to individual therapeutics." (Wilson et al., 2007)

Types of "genetic testing" services

1. Diagnostics: "companies can go to market as soon as they have phenotype-gene association information and the necessary genetic sequencing equipment in hand. (Herder, M., 2009)
2. Pharmacogenomics(also pharmacogenetics): personalized medicine through incorporate genetic information into drug choice
3. Theragnostics: focuses on "integration of information from a diverse set of biomarkers" (Herder, M., 2009)

Regulatory framework

• Regulation is carried out by the FDA and/or the Centers for Medicare and Medicaid Services (CMS)
  • Testing requires both analytically and clinically valid
  • Currently there is ambiguity in the process
