How accurate is the new blood test for Down syndrome?
When receiving a test result from the new blood test for Down syndrome that says "positive," do patients understand there may be a one-in-five chance of a false positive? Or even a one-in-two, depending on the mother's age? Even genetic counselors admit this is difficult to grasp. Continue Reading

The nonmaleficent role of NIPT
At last week's ACMG Annual Clinical Meeting, I presented a poster titled "The Ethics of Non-Invasive Prenatal Testing." It turns out that the logic of my argument could very well be reflected in practice guidelines that are soon-to-be-released. I doubt the force of my abstract submitted last winter is to account for the change. But, it is a bit ironic that because NIPT will cause a test with risk to potentially have greater risk, NIPT has justified itself being inserted as a step before the test Continue Reading

North Dakota enacts law banning Down syndrome-selective abortion
Yesterday, the Governor of North Dakota signed House Bill 1305, prohibiting sex-selective abortion and abortion for genetic abnormality. That same day, the Governor also signed a law banning abortion once a fetal heartbeat is detected. As a result, with abortion being invoked, the media reporting and instant comments devolved into pro-life/pro-choice arguments. But let's look at the actual language of the law that concerns Down syndrome abortions and see what it actually says before we choose Continue Reading
