Which levels are measured in an electrolyte panel?

Electrolyte panels focus on the charged minerals that regulate fluid balance and electrical activity in the body. Sodium and potassium are the primary electrolytes measured because they directly govern osmolality, nerve impulses, and muscle function. Getting their levels right helps assess hydration status, kidney function, and a range of metabolic or clinical conditions; sometimes chloride and bicarbonate are also looked at, but sodium and potassium form the core snapshot of electrolytes. The other items shown are not electrolytes: bilirubin and creatinine relate to liver and kidney function, BUN and cholesterol pertain to renal function and lipid levels, and glucose with uric acid reflect metabolic waste and sugar handling.
