Potassium Test

Fasting Required: Yes 10-12 Hours
Specimen: Blood
Results: 1-2 Business Days
Description: Potassium is an electrolyte that is vital to cell metabolism and muscle function. If potassium levels are too low or too high, there can be serious health consequences; a person may be at risk for developing shock, respiratory failure, or heart rhythm disturbances.
Methodology: Ion Selective Electrode (ISE)
Clinical Significance: Potassium measurements are useful in monitoring electrolyte balance in the diagnosis and treatment of disease conditions characterized by low or high blood potassium levels. Potassium is elevated in adrenal cortical insufficiency, acute renal failure and in some cases of diabetic acidosis. Potassium is decreased in diuretic administration and renal tubular acidosis.
