Study Notes
Critical Analytes and Life Threatening Conditions
- Serum potassium is recognized as the single most critical analyte due to its direct impact on cardiac function; abnormalities can lead to life-threatening arrhythmias.
Major Intracellular Cation
- Potassium (K+) is the major intracellular cation, crucial for various cellular functions.
Reference Range for Serum Potassium
- The reference range for serum potassium is typically between 3.5 to 5.0 mEq/L.
Serum vs. Plasma Potassium Levels
- Serum potassium levels are generally higher than plasma potassium levels due to the release of potassium from platelets during clotting; this leads to slightly elevated measurements in serum samples.
Functions of Potassium in the Body
- Potassium plays a vital role in maintaining normal cell function, regulating fluid balance, transmitting nerve impulses, and muscle contractions, particularly in the heart.
