Direct-to-Consumer Genetic Testing

Meaning

Direct-to-Consumer Genetic Testing (DTC-GT) encompasses genetic analyses offered directly to the public without the mandatory involvement of a healthcare professional for ordering or interpreting the results. These services typically analyze single nucleotide polymorphisms (SNPs) to provide personalized information regarding ancestry, predisposition to certain health traits, or potential drug metabolism profiles. While offering accessible insights into one’s genomic landscape, these tests often provide raw data or interpretations that require careful clinical translation, particularly when considering complex endocrine pathways or pharmacological sensitivities. Consumers must understand that these reports offer risk predisposition rather than definitive diagnoses.
