# Potassium

> This test measures the level of potassium in your blood, a mineral that helps your nerves and muscles, including your heart, work properly. It is useful for checking your body's fluid and electrolyte balance, which is important if you take certain medications or have symptoms like muscle weakness. The results help rule out or identify problems related to kidney function, dehydration, or adrenal gland disorders. However, this test cannot identify the specific cause of an imbalance on its own and is often reviewed alongside other lab results.
