Potassium
- Sample Type
- Standard
- Fasting
- No
- Unit
- mmol/L
Potassium (K+) is the primary intracellular cation and is essential for maintaining the resting membrane potential of cells. In the Basic Kidney Profile, it is monitored because the kidneys are the main regulators of potassium balance. Dysregulation can lead to life-threatening cardiac arrhythmias and muscle paralysis.

Why Context Matters
Pseudohyperkalemia is a common confounding factor, where potassium leaks out of red blood cells during the blood draw (hemolysis) or if the sample sits too long before centrifugation, giving a falsely high reading.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
