Service Providers for Potassium (K)
A Potassium (K) test measures the level of potassium in the blood, essential for nerve function and muscle contraction. It’s used to evaluate kidney function, monitor heart problems, or diagnose electrolyte imbalances. No special preparation is usually needed. Blood is drawn from a vein, which may cause mild discomfort. Risks include bruising or fainting. Results show normal levels (3.5–5.0 mmol/L); low potassium (hypokalemia) or high potassium (hyperkalemia) may indicate kidney issues, heart problems, or dehydration. Medications and certain health conditions like kidney disease can affect results. Your doctor will interpret the findings based on overall health and symptoms.
