When asked why he bestowed such a title upon a person who is known as an irreligious man, Rabbi Yosef Yitzchak replied:
“When a pathologist is given a blood sample or a particle of body tissue to analyze in his laboratory, he peers at it through his microscope and subjects it to a series of chemical tests and procedures. If he finds so much as the slightest trace of a certain element, or a single cell of a certain organism, he notes this in his report. For though the quantity he discerns might be minuscule and hardly worthy of regard, it points to the existence, or the potential for the existence, of much greater quantities in the person.

She was an American girl from California who had just discovered her Jewish roots. She was learning in a girls’ seminary for people just like her. But her mother had not yet accepted this determination of hers to become religious, and every visit to her home in California ended up being a nightmare of disagreements and explosions.
“That’s it!” She told her friends. “I am cutting off relations with my mother. If she isn’t willing to accept me, then I won’t accept her.”
Her friends begged her: “This is a fateful move. Go the Rebbe, ask him for his advice.”
Recently the question has been posed, when should one check for DY compatibility – before considering any suggestions or only after both sides have done their due diligence and are ready to proceed to date?
In my opinion, DY checking should only be done once all due diligence has finished and both families are ready to proceed. The exception would only be in the circumstance where both sides are aware that a specific genetic problem may be present. Otherwise, protocol is not to check DY every time a suggestion is made.
