When my oldest daughter was pregnant, her blood work showed her to be a carrier of CF. Her husband was then tested, and he is not a carrier. However, my second daughter was worried that she too may be a carrier and asked her doctor to test her. She is also a carrier. She is 25 years old and in a committed relationship. In fact, she and her boyfriend plan on getting engaged soon. My daughter wants her boyfriend to get tested to find out if he is a carrier. He doesn't want to be tested because he says that it wouldn't matter to him if he was a carrier. He doesn't want their relationship or plans for the future to be affected by the test results. However, to appease her, he asked his doctor about being tested. His doctor said that he wouldn't give him the test unless she was pregnant. My daughter is very concerned. she says that she would still marry him if he is a carrier, but she wants to know. Actually, she wants to know that he is not a carrier and then her fears can be alleaved. However, it's impossible to know what the test results would be. Knowing what you all know about CF, would you avoid it at all costs? Or would you wait until pregnancy to find out if there is a possibility of the child having CF (abortion is not an option)? I feel that you never know what difficulties your child may have, whether CF or any other special needs, from birth or later in life. Am I giving her bad advise? I hope this is not too confusing.
