Potassium

Potassium is predominantly present inside the cells throughout the body, and the kidneys regulate its level. It performs several vital functions, such as regulating fluid levels, balancing the acid-base (pH) levels, or maintaining nerve and muscle functions. Potassium is also essential for the proper functioning of the heart. Therefore, any fluctuations in its levels can be alarming as this can cause potentially serious health concerns.

Your doctor may advise the Potassium test if you experience symptoms such as extreme fatigue, chest pain, irregular heartbeat, irregular pulse, difficulty in breathing, muscle weakness, and numbness. This test is also used as a follow-up test for those undergoing diuretic therapy or kidney dialysis. Usually, no special preparation is required for this test; eat and drink as per your daily routine.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. Narrate your complete medical history to help the doctor correlate your clinical and laboratory findings. The test results will help them determine your medical condition, make recommendations for lifestyle modifications such as diet and exercise, decide whether or not medication will be required to manage your health and formulate your overall treatment plan.
