Such assays generally fall into one of six categories:
- Assays that screen for disease in an apparently healthy population
- Assays used to aid in the diagnosis of a particular disease
- Assays that monitor a disease or the efficacy of its treatment
- Assays that stratify risk for a particular disease
- Assays that prognose the natural course of a disease or condition
- Assays that predict response to a therapeutic intervention (often called a ‘companion diagnostic’)
