A Potassium Test measures the level of potassium in your blood. It helps evaluate muscle function, nerve activity, heart rhythm, kidney health, and electrolyte balance in the body.
Doctors recommend a Potassium Test if you experience symptoms like muscle weakness, fatigue, irregular heartbeat, cramps, dehydration, or kidney-related issues. It is also commonly advised for patients taking blood pressure or diuretic medications.
No fasting is required for a Potassium Test. However, your doctor may provide special instructions depending on your medical condition or if the test is part of a larger health profile.
Low potassium levels may cause weakness, muscle cramps, or irregular heartbeat, while high potassium levels can affect heart function and may indicate kidney or metabolic disorders.
The test is done using a simple blood sample, usually collected from a vein in your arm. The sample is then analyzed in the laboratory to measure potassium levels accurately.
Potassium Test reports are generally available within 16 hours, depending on the laboratory processing time.
Yes, you can conveniently book a Potassium Test online with home sample collection or visit the lab directly for testing.
