sweat test

a test for cystic fibrosis of the pancreas in which electrolytes are measured in collected sweat; sodium chloride concentration above 50 mEq/L (children) or 60 mEq/L (adults) is positive.

sweat test

A laboratory test that measures the amount of chloride and sodium in a patient's sweat, performed to diagnose cystic fibrosis.

sweat test

a method for evaluating sodium and chloride excretion from the sweat glands, often the first test performed in the diagnosis of cystic fibrosis. The sweat glands are stimulated with a drug such as pilocarpine, and the perspiration produced is analyzed. The eccrine glands of patients with cystic fibrosis produce sodium and chloride concentrations that are three to six times normal. Chloride levels above 60 mEq/L and sodium levels above 90 mEq/L are considered diagnostic for the disease. The test is very reliable, and although it may be useful at any age, it is usually performed on infants from 2 weeks to 1 year of age. See also cystic fibrosis.

sweat test

Pediatrics A test used to diagnose cystic fibrosis–CF, which is characterized by defects in secretion–especially of sodium and chloride–by exocrine glands. See Cystic fibrosis. Cf Sweat testing.

Cystic fibrosis; etiology, diagnosis and treatments

Based on positive quantitative sweat test [greater than or equal to] 60 mmol/L and the presence of 2 cystic fibrosis-causing mutations, we made the diagnosis of cystic fibrosis.

When to suspect atypical cystic fibrosis: not all patients with cystic fibrosis have abnormal sweat chloride levels, severe lung disease, or failure to thrive. These 2 cases remind us to think "outside the box."
