Direct-to-consumer genetic testing and public safety

Genetic testing allows us to identify the likelihood of us getting illnesses and diseases, as well our response to certain medications. Over the years it has become increasingly popular, especially in the area of direct-to-consumer genetic testing (DTC GT) – testing sold directly to consumers without the involvement of their doctor. Individuals simply order a personal testing kit either via the Internet, television or other marketing or advertising avenues, provide a saliva sample, mail it to the lab and await the results. And while the sophistication of DTC GT has increased, cautions should still be taken.

If the privacy of DTC GT results isn’t adequately maintained, potential for harms include discrimination and stigmatization. For example, employers or insurance companies may deny individuals employment, benefits, medical coverage or health insurance based on knowledge of genetic disposition. Additionally, test results could lead to improper use of other health care services such as an inappropriate demand for medications and/or inadequate or incorrect changes in medication by the consumer.

It is imperative that DTC GT not compromise quality patient care, and that consumers don’t use this type of testing to making decisions about their health without the advice of their doctor. And since DTC GT isn’t currently regulated, in a recent policy statement Doctors of BC is calling for the following to better protect consumers:

• Federal regulation of marketing and health-related claims in connection with DTC GT
• The development of national standards for reliability and validity of DTC GT
• Public education initiatives aimed at increasing awareness of potential implications
• Increased education for physicians on interpreting test results
