Blood biochemistry: potassium

Synonym(s): K

Contributor(s): Vetstream Ltd, David Perpinan

Overview

  • 98% of potassium is intracellular but passive and freely diffusible in and out of cells.
  • Major intracellular cation.
  • Changes in plasma levels reflect fluid balance, rate of renal excretion and changes in balance between intra- and extracellular fluid.
  • The body maintains potassium concentration primarily through the action of the kidneys. Both aldosterone and antidiuretic hormone (ADH) increase potassium loss into the urine.
  • The pH of the extracellular environment is one of the major influences on potassium serum concentration. Acidotic conditions increase serum potassium, and alkalotic conditions decrease serum potassium.
  • Insulin also causes a decrease in serum potassium, as do catecholamines and increased thyroid hormones.
