What is the normal potassium level range?

The normal potassium level range in the blood is essential for various physiological functions, including nerve impulse transmission and muscle contraction. The correct range is between 3.5 to 5.0 milliequivalents per liter (mEq/L). This range is based on standard laboratory values that reflect the concentration of potassium needed for optimal cellular function and overall homeostasis.

Levels below or above this range can indicate various medical conditions. For example, hypokalemia (low potassium) can lead to muscle weakness, arrhythmias, and other issues, while hyperkalemia (high potassium) can have serious cardiovascular implications.

The other ranges provided are either too narrow or outside the standard reference values, which may lead to misinterpretation of a patient's electrolyte status, potentially impacting clinical decisions and patient care. Recognizing the accurate range is critical for healthcare professionals in monitoring and managing electrolyte imbalances.
