Gene Testing Often Gets It Wrong

BarbaraHudson writes: ABC is reporting that gene tests for risk of specific diseases are not as accurate as we'd like to think, with different labs giving different interpretations. Over 400 gene variants that could help one make medical decisions regarding breast and ovarian cancer or heart disease have different interpretations from different labs according to the study. "The magnitude of this problem is bigger than most people thought," said Michael Watson, executive director of the American College of Medical Genetics and Genomics, one of the study's authors. Researchers caution consumers to be careful when choosing where to have a gene test done and acting on the results.

Maybe Mr Testing should pay more attention to his work.

If a 99% accurate test is true, but the probability of the condition is only 0.0001%, it is still highly improbable that the person is afflicted by the condition on the basis of the test alone. Its important to narrow down the population before any testing is effective.
