Test Description: Potassium

The Potassium test measures the level of potassium, a key electrolyte, in the blood. Potassium plays a vital role in maintaining proper heart function, muscle contraction, and nerve transmission. Abnormal potassium levels, either too high (hyperkalemia) or too low (hypokalemia), can lead to serious health issues, including heart arrhythmias, muscle weakness, or paralysis. This test is often used to assess kidney function, monitor patients on certain medications (like diuretics), or evaluate conditions like dehydration, kidney disease, and metabolic disorders.
