Matchmaking and Genetic Testing

Hello,\r\nPlease, if possible, forward the question to the esteemed Rabbi Frid,\r\n\r\nThe mother of my son's match approached me because she wants them to undergo genetic testing after consulting with a medical institute.\r\n\r\nI would like to note that my son already informed the match about the medical information during the first month.\r\n\r\nAt her request:\r\n1. Two brothers have been diagnosed with autism,\r\nand it is required: genetic blood test for both, including the matched son.\r\nWhich is very difficult for both brothers to undergo a blood test.\r\n\r\n2. He has an eye disease, keratoconus,\r\nshe requests that he undergo a test for this. \r\nAfter checking with his doctor, he was informed that for a genetic test, all brothers (8 brothers in the family, including him) need to be tested as well.\r\n\r\nI am very concerned for my son,\r\nthey have known each other for 3 months\r\n\r\nAnd really need urgent advice on what to do, whether to proceed and ask all brothers to undergo eye tests, and even though I fear that for the 2 brothers with autism there will be resistance to undergo a blood test?

Peace and blessings 

According to the instructions of the Gaon, Rabbi A. Frid, shlita:

A. It is not possible to force someone to undergo a genetic test; only those who agree will do it. 

B. Today, through artificial insemination, it is possible, with God's help, to check and arrange everything.
