Genetic Testing
Genomic Tests and Family History by Levels of Evidence
The CDC Office of Public Health Genomics provides the following list of genomic tests and applications in practice according to three levels of evidence based on the paper by Khoury et al
. This list is provided only for informational purposes to researchers, providers, public health programs and others. The most recent additions to the list are applications relevant to family health history based on existing recommendations from the US Preventive Services Task Force. For additional information on updates to this list, read our accompanying blog.Tier 1 genomic and family health history applications are recommended for clinical use by evidence-based panels based on a systematic review of analytic validity, clinical validity and utility for specific clinical scenarios

Tier 3 genomic and family health history applications have not demonstrated adequate analytic validity, clinical validity, or clinical utility. This also includes applications for which evidence-based panels have recommended against their use based on the synthesis of the balance of benefits and harms. Such applications are not ready for routine practice, but may be considered in clinical and population research.
