Potassium RBC

Potassium is one of the main electrolytes in the body that is important to maintain healthy cell functions. Potassium helps to transport nutrients into cells and waste products out of cells. It is needed for healthy muscle and nerve communication and function. Potassium, along with the other electrolytes, help to regulate the amount of fluids in the body. A potassium rbc blood test is more accurate than a standard blood potassium test, and will show a potassium deficiency much earlier. This test is useful in the diagnosis of kidney disease, adrenal cortical insufficiency and problems with the heartbeat.

This test is performed in following conditions such as:

• Routine medical examination
• Kidney disease
• Muscle weakness
• Irregular heartbeat
• Medications like diuretics or heart medications
• High blood pressure
• Patients receiving dialysis
