Potassium levels

Potassium levels refer to the concentration of potassium ions in the blood, typically measured in millimoles per litre (mmol/L). Maintaining appropriate potassium levels is crucial for normal cellular function, particularly in cardiac and muscle tissues, as both hyperkalemia and hypokalemia can lead to serious complications such as arrhythmias or muscle weakness. Clinically, potassium levels are monitored in patients with renal impairment, heart disease, or those on certain medications.
