Can you live without knowing you have cystic fibrosis?

Yes, it is possible to live without knowing you have cystic fibrosis. In some cases, symptoms may be mild and go unnoticed for years, or be mistaken for other conditions. In other cases, cystic fibrosis may not be diagnosed until later in life, after symptoms have become more severe.

However, early diagnosis and treatment are important for managing cystic fibrosis and reducing the risk of complications. Newborn screening tests can help detect cystic fibrosis early and allow for early intervention, which can improve long-term outcomes.
