Potassium- Reference Levels

Potassium is an essential electrolyte, which is a mineral your body needs to function correctly. Potassium is especially important for your nerves and muscles, including your heart.

The normal range of potassium is between 3.6 and 5.2 millimoles per liter (mmol/L). A potassium level higher than 5.5 mmol/L is considered critically high, and a potassium level over 6 mmol/L will be life-threatening.

High potassium levels may indicate:

  • Kidney failure
  • Trauma
  • Dehydration
  • Type 1 diabetes
  • Addison’s disease
  • Internal bleeding

Besides, taking some medications may lead to high potassium levels. These medications include certain chemotherapy drugs, angiotensin receptor blockers and angiotensin-converting enzyme (ACE) inhibitors.
