Poor Prenatal Diagnosis Index

We do our best to compile informative diagnosis information pages to save you the trouble of running across upsetting search engine results. We try to condense each poor prenatal diagnosis into plain language, then provide hyperlinks to three or more respected medical websites. We will not link our prenatal diagnosis pages to blogs, news articles or “advocacy” sites.

We are not medical professionals and the information on our website is not intended to serve as medical advice. It is simply here as a convenience to our readers. This is not an exhaustive list of poor prenatal diagnosis.

If you’ve received a poor prenatal diagnosis and are in the throes of decision making, we encourage you to do your own research, as well as talk to your doctor, perinatologist or genetic counselor about the particulars of your prenatal diagnosis.
