I thank you, Dr. Pepper, for your thoughtful reply. BTW, I know a couple that did not get married who had been tested, but were not notified what the incompatibility was, only that it was not shayach. I don’t doubt the validity of the reasoning at D”Y, I just feel it would be better to let people know what is going on with them. Even if the parents themselves are tested, that doesn’t say what the kids may or may not have inherited from them.
