A blood test before birth could predict your medical destiny – CNN reports


In 1996, Prof Dennis LO discovered a “treasure trove” of valuable DNA floating freely in the bloodstream. With this discovery, Prof LO made it possible for pregnant women to safely screen their unborn children for genetic conditions, to map out the entire genome of their fetus, and potentially screen all ages for cancer at its earliest stages. All using a simple blood test. After 20 years, Prof LO now moves on to an even less invasive form of DNA testing — using a mother’s urine.
