<section begin="clinical biochemistry" />'''Hyponatraemia''' is a disorder of [[sodium]] homeostasis characterised by low levels of sodium (< 135 or 136 mmol/L). It's the most common electrolyte abnormality, affecting 3-10% of patients in the emergency department. It's usually mild and is self-limiting, but severe hyponatraemia is lethal. Determining the volume status and serum osmolality of the patient is important in determining the cause. Treatment involves water restriction or sodium repletion.
