Hello this is my first message to this sight. I am a mother of 4 and my 4 yr old has CF. He was diagnosed at 2mos. old through genetic testing. He has not been sick since. He will be 5 in September and he has been off all meds for 2 yrs now due to insurance issues. I'm really scared. I think I am making him worse. His pediatrician says he is perfectly healthy. Bloodwork, weight gain,and lungs are clear. I am not very familiar with all the gene testing but what can you get from finding out the specific mutations? Does this effect how healthy he is or is his doctor lying to me. Please help I am very concerned and confused. Any comments or suggestions would be helpful.
