News from just the past week has featured a number of questionable headlines. See if you can spot what’s wrong about them.
- Noninvasive prenatal testing is so good at ruling out certain fetal abnormalities that rates of more invasive procedures have plummeted.
- “It can’t be diagnostic for the fetus. We’re not really assaying the fetal nucleic acids; we’re assaying a mix of placenta and mother,” [Bianchi] said.
Again, what is wrong about the headline based on what is reported in the article:
Dr Sheila Macphail, consultant in Obstetrics and Fetal Medicine at the RVI, said: “A small amount of DNA from the unborn baby always circulates in the mother’s blood stream.
“The new technology allows this small amount to be identified and amplified permitting greater diagnostic accuracy. Any results which indicate a high risk would then require a further diagnostic test.
“We still advise expectant mothers to have their usual ultrasound scans and testing for Down’s Syndrome as part of their routine NHS care.”
