Electrolytes
Na+
K+
Cl-
HCO3-
Ca
Vitamin D |
|
Definition
Na+ : sodium, major cation
K+ : potassium, chief cation (hyperkalemia- raised K+ levels-> metabolic acidosis)
Cl- : chief anion(hyperkalemia-raised levels-> renal tube acidosis)
HCO3- : bicarb, raised in metabolic alkalosis, lowered in metabolic acidosis. Normal levels 22-26 mEq
Ca : calcium
Vitamin D |
