The sweat test for cystic fibrosis [letter].

The major issue is not the "lack of interest of clinical chemists," 
but the actual performance of the test. Neither the pathologist nor 
the clinical chemist, in all likelihood, actually performs the test. Rather, 
it is the medical technologist or technician who carries out the 
actual procedure. It is a major part of our roles as 
educators and laboratory administrators to ensure that these people are adequately 
trained for the task and that the test meets high enough 
performance standards to provide a clinically relevant answer.
