Metabolic / Electrolytes
Also known as: potassium serum, serum potassium, serum electrolytes
If you experience severe symptoms like chest pain, heart palpitations, severe muscle weakness, or trouble breathing, seek urgent medical care immediately.
This blood test checks how much potassium is in your blood. Potassium is a special helper in your body. It helps manage your body's fluids. It also helps keep your body's balance right. And it helps your muscles and nerves work well.
Your doctor might order this test during a regular check-up. They may also order it to keep an eye on health problems you already have, like diabetes or kidney disease. This test is also used if you take medicines that can change your potassium levels.
Potassium levels can vary, and what's considered normal can depend on the lab that does your test. Your doctor will help you understand your specific results.
