Re: my 18 months old dignosed as Classic CF
Based on the symptoms, I would pursue more extensive genetic testing. There are over 1500 different mutations for CF and mosts tests only include the most common mutations -- so 30-90 out of a much larger number.
DS' sweat test was a normal 32 at about 4 weeks; however, genetic testing showed otherwise. He tends to have more digestive issues. What are your child's stools like? Are they normal or are they frequent, greasy, bulky, very smelly?
