Sweat test

Question
May a child have CF, even if the sweat test is negative?
Answer
Dear Mrs.
Yes and no. It is a difficult and complex question. It depends on the patient's clinical condition and his medical history. It is very important that this sweat chloride test is conducted correctly in a laboratory which has enough experiences with this test. Negative sweat chloride test should exclude the typical form of CF. In suspicion of CF it is necessary to contact the Center for treatment of cystic fibrosis.
