Popa, DY: I don’t think that it’s a monopoly on purpose, but effectively it is one. If I decided on my own that I wanted to be tested by 23andme, bd”e (whatever I may think of the advisability of that), should I really not be able to be tested by Dor Yeshorim? Having whatever recessive gene should not be a stigma, but as it does seem to be one for some people and everyone wants to be tested for these diseases, you kind of HAVE to go through Dor Yeshorim, which prevents you from doing anything else beforehand. (Afterward, sure, but by then you’ve already used them…)
I’m not saying that they’re TRYING to have a monopoly, and their logic makes sense (once you come to terms with the fundamental assumptions about stigma), but it’s frustrating that there IS such a monopoly.
