Indus Dolphins sleep even though it's dangerous. These dolphins exist in muddy water and through natural selection have become blind because it served no purpose. Why then do they still sleep?
Sweat chloride measurements are used in the laboratory diagnosis of cystic fibrosis. Chloride Titration. The ChloroChek Chloridometer is a coulometric titrator designed to determine chloride ion concentrations in sweat samples with just 10 microliters of sweat. It displays the concentration directly in mmol/L Cl-. The sweat sample is added to an acid buffer/stabilizer working solution.
Chloride is an electrolyte that helps keep a proper fluid and acid-base balance in your body. The chloride blood test, or serum chloride level, is often a part of a comprehensive metabolic panel or a basic metabolic panel.
