Definition
If the urine is alkaline, with an elevated [Na+] and [K+] but low [Cl–], the diagnosis is usually either vomiting (overt or surreptitious) or alkali ingestion

neither the urine sodium, potassium, nor chloride concentrations are depressed, magnesium deficiency, Bartter's or Gitelman's syndrome, or current diuretic ingestion should be considered |

|
|
Term
a low urine chloride concentration in a patient with unexplained metabolic alkalosis and hypokalemia usually reflects vomiting or prior diuretic therapy |
|
Definition
|
|
Term
The distinction between vomiting and diuretic therapy in this setting can be made only if the characteristic physical findings of self-induced vomiting are present, if a urine assay for diuretics is positive, or if the urine chloride concentration is high at a subsequent measurement (because the diuretic is acting) while the patient still has metabolic alkalosis |
|
Definition
|
|
Term
a urine chloride concentration that is not low suggests either continued diuretic therapy or Bartter or Gitelman syndrome |
|
Definition
These disorders cannot be distinguished in the absence of a history of diuretic use or a positive urine assay for diuretics, since they have identical clinical manifestations and pathogeneses |
|
|
Term
metabolic alkalosis represents one of the conditions in which volume depletion may not lead to a low urine sodium concentration |
|
Definition
|
|
Term
The presence of underlying hypovolemia can be detected more accurately by finding a urine chloride concentration below 25 meq/L |
|
Definition
|
|
Term
he urine chloride concentration, however, may be inappropriately elevated if there is a defect in chloride reabsorption. This most commonly occurs with diuretic therapy and is transient, as chloride is appropriately conserved once the drug effect wears off. Marked hypokalemia (plasma potassium concentration below 2 meq/L) also can reversibly impair chloride transport, leading to a rise in chloride excretion that is independent of volume status |
