EVALUATION OF HYPONATREMIA 

Urine osmolality and urine sodium concentrations are essential in the differential diagnosis of hyponatremia. The basic urine metabolic panel provides both of these together. Serial determinations, for example, before and after administration of isotonic saline can be helpful. In hypovolemic hyponatremia, urine sodium excretion may remain low after volume resuscitation as the urine osmolality falls; in the syndrome of antidiuretic hormone secretion, urine sodium rises and the urine osmolality remains elevated.

低钠血症的评估

尿渗透压和尿钠浓度在低钠血症的鉴别诊断中必不可少。尿液代谢组套检查同时提供这两种检查。例如，在给药前和给药后进行一系列的测定可能对鉴别诊断会有帮助。在低血容量性低钠血症患者中，在容量复苏后因尿渗透压下降尿钠排泄量可能仍然较低；而在抗利尿激素分泌综合征患者在容量复苏后，尿钠会升高和尿液渗透压仍然升高。

In hypovolemic hyponatremia, urine sodium excretion may remain low after volume resuscitation as the urine osmolality falls; in the syndrome of antidiuretic hormone secretion, urine sodium rises and the urine osmolality remains elevated.

urine sodium rises and the urine osmolality remains elevated  后面是不是省略after volume resuscitation
