What is a critical potassium level?

Potassium is a chemical that is critical to the function of nerve and muscle cells, including those in your heart. Your blood potassium level is normally 3.6 to 5.2 millimoles per liter (mmol/L). Having a blood potassium level higher than 6.0 mmol/L can be dangerous and usually requires immediate treatment.

Is potassium level 5.3 high?

A potassium level higher than 5.5 mmol/L is critically high, and a potassium level over 6 mmol/L can be life-threatening. Small variations in ranges may be possible depending on the laboratory.

What do potassium levels indicate?

In the right amounts, the mineral potassium helps your nerves and muscles “talk” to each other, moves nutrients into and waste out of your cells, and helps your heart function. Kidney disease is a common cause of a high potassium level. Either high or low potassium levels can cause heart problems.
