Sweat

Sweet test sponsored in the sweat investigation test, the chlorine content in sweat is examined, and the reason for its procedure is to know how to produce sweat, as the sweat in the glands is produced under the skin controlled by the autonomic nervous system (sympathetic) for sweating. The sweat fluid contains the different plaspa punents, as well as a certain amount of sodium chloride, in cystic fibrosis, there are large amounts of chloride in sweat, so this examination is from the set of tests to diagnose cystic fibrosis. The method of conducting the investigation in this test is placed a colorless and odor chemical called Pilocarpine on a small area of ​​the arm or leg to encourage the sweat glands to secrete sweat; The person may feel a tingling in the area. This part of the test takes about five minutes. The sweat is then collected on a filter and the salt content is measured. Analysis of the results to understand what the results of sweat examination mean that it is important to read the following points: The level of chloride is less than or equal to 29 millols/ l, which means cystic fibrosis is unlikely, regardless of age. The chloride level is between 30 – 59 millols/ l, which means that cystic fibrosis is possible and that an additional test should be investigated. The level of chloride is greater than or equal to 60 millol/ l, the patient is diagnosed with cystic fibrosis. In addition, in the following cases we can see a large amount of chloride in sweat: insufficiency of adrenal glands. Galicogen storage – Von Gierke’s Disease – Glycogen storage disease. False diabetes involved in a defect in the production of vasopressin diabets insipidus. Kidney failure.
