Diagnosis of Cystic Fibrosis: Sweat Test

A sweat test is the standard method used to make the diagnosis of cystic fibrosis (CF). This test is simple and painless. It requires no special preparation. Before the sweat test the baby can be fed, bathed and cared for as usual. Parents may remain with their baby while the test is being done.

Cystic Fibrosis Prognosis

Since cystic fibrosis was first identified in 1938, advances in its diagnosis and treatment have led to marked improvement in the quality and length of life for people with cystic fibrosis.

During the 1940s, few children survived their first year. In 2005, the average age of survival was 36.8 years, an increase from 35.1 in 2004 and an increase from 32 years in 2001. Many people live well into their thirties and forties. With continued medical advances a baby born with cystic fibrosis today may live well into his/her fifties or sixties.
