Direct-to-consumer (DTC) testing offers health insights but requires careful consideration. Consumers should weigh the benefits of DTC genetic testing against potential risks like privacy concerns and misinterpretation of results.
Area of Science:
- Genetics
- Consumer Health
- Laboratory Medicine
Background:
- Direct-to-consumer (DTC) testing is increasingly popular, driven by convenience and a desire for health control.
- These tests provide insights into health status, disease risk, ancestry, and medication response without physician orders.
Purpose of the Study:
- To review the perceived and potential benefits of DTC testing.
- To discuss the potential risks associated with DTC testing.
Main Methods:
- Literature review of recent publications on DTC testing.
Main Results:
- DTC testing offers enticing benefits, driving market growth.
- Potential risks include privacy issues, confusing results, emotional distress, misdiagnosis, and over-testing.
Conclusions:
- Consumers must balance the advantages of DTC testing against its inherent risks.
- Informed decision-making is crucial for individuals utilizing DTC health information.
