Chloride is an electrolyte. When combined with sodium it is mostly found in nature as “salt.” Chloride is important in maintaining the normal acid-base balance of the body and, along with sodium, in keeping normal levels of water in the body. Chloride generally increases or decreases in direct relationship to sodium, but may change without any change in sodium when there are problems with too much acid or base in your body. Chloride is taken into the body through food. Most of the chloride is absorbed by the gastrointestinal tract, and the excess is excreted in urine. The normal blood concentration remains steady, with a slight drop after meals (because the stomach produces hydrochloric acid after eating, using chloride from blood).
How is the sample collected for testing?
A blood sample is taken by needle from the arm. Chloride can also be measured in a urine sample.
Is any test preparation needed to ensure the quality of the sample?
No test preparation is needed.
