Please support lifesaving research today. He said expectant mothers should always consult a well-trained doctor or geneticist to determine the PPV so they can make an “informed decision.”, “It seems like math mumbo jumbo when you put the numbers together,” said Skotko. Most ppl would get the cvs done and if any grey area in results go onto amnio aswell, but on most part u wouldn’t need to cvs would give the answer. Really aggravating the Amnio didn’t show more.
