Overview
Hyperkalemia (AE) or Hyperkalaemia (BE) is an elevated blood level (above 5.0 mmol/L) of the electrolyte potassium. The prefix hyper- means high (contrast with hypo-, meaning low). The middle kal refers to kalium, which is Latin for potassium. The end portion of the word, -emia, means "in the blood". Extreme degrees of hyperkalemia are considered a medical emergency due to the risk of potentially fatal arrhythmias.
Lab tests
Initial
- Calcium
- Phosphate
- Magnesium
- Blood urea nitrogen (BUN)/creatinine
Extensive Evaluation
- Cortisol
- Renin
- Aldosterone levels
- Transtubular potassium gradient (by assessing potassium+ secretion)
