Viewpoint: Will consumer genetic tests disrupt the physician-patient relationship?

In an op-ed published in the state medical association journal Missouri Medicine, Joel Eissenberg, PhD, asks whether the rise in direct-to-consumer genetic testing is harmful or empowering for patients.

Dr. Eissenberg, a professor of biochemistry and molecular biology at Saint Louis University, noted how recent scientific advancement has led to less expensive genetic sequencing. Today, healthcare consumers can order mail-in genetic tests to learn about inherited traits, such as whether they carry an increased risk of diseases like breast cancer or Alzheimer’s.

Dr. Eissenberg emphasized that patients should have the autonomy to access their own genome data. “At its best, direct-to-consumer genomics testing could eventually become like other forms of home medical testing — another way for people to take personal control of their health and wellness,” he wrote.

However, Dr. Eissenberg also raised some concerns, including patients’ potentially limited understanding of genetics, which can lead to confusion without proper guidance from a physician or genetic counselor. To address these issues, he said patients should consult a medical professional for assistance in interpreting their results.
