Direct to consumer versus clinical genetic testing.

There are approximately 250 direct to consumer (DTC) genetic testing companies marketing different testing options such as genetic health risk, carrier status, ancestry, wellness, traits, noninvasive prenatal genetic testing, athleticism, and many others.

A wealth of information may be discovered and care must be taken by both consumers and clinicians when deciphering test results. This column highlights considerations when proceeding forward with a DTC genetic test.
