of Using DTC Genetic Tests
These tests may encourage
and empower consumers
to take a proactive role
in their health care.
Potential Risks of Using
DTC Genetic Tests
These tests may mislead or
misinform people about
their health status.
DIRECT-TO-CONSUMER GENETIC TESTING
Direct-to-consumer (DTC) genetic tests are marketed directly to consumers, in contrast to tests
that are ordered by a physician for a patient. This growing form of testing, also known as at-home
testing, allows a consumer or patient to obtain access to his or her genetic information without
necessarily involving a doctor or insurance company in the process. Below are a number
of important facts about DTC genetic tests.
Because of the complexities of such tests, both the FDA and Federal Trade Commission recommend
involving a health care professional in any decision to use DTC testing, as well as to interpret the results.

DTC Genetic Tests and the FDA
DTC tests that claim to provide only information such as a person’s ancestry
or genealogy are not regulated by the U. S. Food and Drug Administration (FDA).
In February 2015, however, the FDA authorized marketing of the first DTC genetic
test: 23andMe’s Bloom Syndrome carrier test. This test can help determine whether
a healthy person has a variant in a gene that could lead to his or her children
inheriting this serious disorder.
