Overview

  • Present mainly in extracellular fluid but freely diffusible throughout ECF.
  • Usually base excess in diet so dietary alterations unlikely to affect concentrations in body.
  • Regulated by kidneys and important in regulation of fluid balance.
  • Sodium and chloride ions are the most osmotically active solute in plasma.
  • Measured in conjunction with other electrolytes, eg chloride and potassium Blood biochemistry: potassium where metabolic disturbances may be suspected, eg diarrhea. Always assess in association with osmolality where pseudohyponatremia (isotonic/hypertonic) is not significant, whereas true hyponatremia (hypotonic) is significant.
  • In combination with urine electrolyte concentrations for fractional electrolyte excretion in assessment of renal failure.
