NTSAD - If I already have a healthy child, do I still need to have carrier screening?
Category: General Topics
Yes. If you and your partner are carriers for the same recessive disease, there is a 25% chance with each pregnancy that your child will be affected with the disease as well as a 75% chance of having an unaffected child. Two carrier parents could have several healthy children before having an affected child.
