Sodium/Potassium Ratio
The sodium/potassium ratio compares the two main electrolytes in blood. Sodium predominates outside cells, potassium inside. The body keeps the ratio remarkably stable through kidney filtering and hormonal control.
Why it matters: Shifts in the sodium/potassium ratio can reflect changes in fluid balance, adrenal hormone output, or kidney handling of electrolytes. It is a context indicator alongside the absolute sodium and potassium values.

What is Sodium/Potassium Ratio?
The sodium/potassium ratio compares the two main electrolytes in blood. Sodium predominates outside cells, potassium inside. The body keeps the ratio remarkably stable through kidney filtering and hormonal control.
What might a high or low Sodium/Potassium Ratio mean?
Shifts in the sodium/potassium ratio can reflect changes in fluid balance, adrenal hormone output, or kidney handling of electrolytes. It is a context indicator alongside the absolute sodium and potassium values.
What can affect Sodium/Potassium Ratio?
It may be higher with: High sodium intake, Low potassium intake, Adrenal hyperfunction. It may be lower with: Low sodium intake, High potassium intake, Adrenal insufficiency.
