10% of CF diagnosis occurs right after childbirth.
10% of CF diagnosis is usually done not long after a child is born, but it may also be found during a routine examination. There are a few tests to check for CF. There is the Sweat Test, which checks the amount of salt one's skin is secreting. They may also perform a genetic test to look for the mutated gene. As of 1968 the Chorionic Villus Sampling test became available to test for CF and similar diseases in the sample of amniotic fluid of an unborn fetus. The more common test would be a gene test to be done on the parents, for it was discovered that if both parents carried the gene it was 100% guaranteed that their child would then inherit the deadly disease.
