1. If one of my children has CF, should my other children be tested?
Yes. If the genetic mutations causing your child’s CF are known, your doctor may prefer to test the other siblings for these specific mutations. This will let you know if your children have CF or are just carriers. Carriers are not ill and do not need treatment, but they may want to consider genetic counseling before they decide to have children themselves. Some argue that testing on siblings not be done unless they are symptomatic; testing and counseling for reproductive choices can be done later.
2. What other tests may my doctor recommend if my child has CF?
Your doctor may do other tests, such as chest X-rays as well as lung function and pancreas function testing, to find out how severe your child’s CF is. This can guide them in recommending a treatment plan and/or a referral to a special CF center where your child can get expert help, advice, and monitoring.
