I think it's all good potential revenue for CBAI but DNA testing is a total "psyche" thing for the expectant parents. As an administrator for a Neonatal ICU for many years, I see it everyday. Parents absolutely mourn over the loss of their anticipated experience of a perfect birth ie something goes wrong in the delivery room or during the pregnancy.
I'm not saying the concept is logical or anything...it just is what it is. When a woman becomes pregnant, she has a love affair with her unborn baby and all the future holds for the family. I know, I have 3 children myself. If a family has a baby in the NICU for more than a week, they adjust. For those parents who spend a few hours or few days with their baby in the NICU, the experience is devastating. Believe it or not the impact is more severe than having a baby in the NICU for several weeks. I tell you all this gobbly gook to help identify where the opportunity is IMO, which is not as a wellness or a preventative decision.
Just as the cord blood business went to the Obstetricians before they experienced any real success, I think DNA testing would find the earliest success with Maternal Fetal Medicine docs or physicians who specialize in perinatal medicine. The women seeking care from these physicians are high risk. They know their baby will have some problems and the goal would be to minimize the impact in any way possible. I'm not saying the MFM would be a "salesman". The physicians I have met in this specialty are some of the greatest in all of medicine in my experience. I think they are the target audience, however. AIMVHO of course.
