I have an appt with the doctor today. Mu husband and I will get the results of the genetic testing they did to check the mutation of our genes. I am nervous becuse the counselor said there is a 5% chance that some genes are not detctable. they will use our blood test to compare it to my amnio or cvs sample when they do it very soo. has anyone had any experience with this where the genes were undetectable? Let me know.
