Potassium- Serum
What does Potassium- Serum measure?
This test measures the level of potassium in the blood. Potassium is an important mineral that helps support normal nerve signaling, muscle function, and heart rhythm. A healthcare professional may order it to assess electrolyte balance, monitor kidney function, or evaluate conditions or medicines that may affect potassium levels. Results are interpreted along with symptoms, medical history, and other laboratory findings.
