URINARY POTASSIUM (K)
The Urinary Potassium (K) test measures the amount of potassium excreted in the urine. Potassium is an essential electrolyte that plays a vital role in maintaining proper nerve function, muscle contraction, and heart rhythm. This test helps evaluate kidney function and the body’s electrolyte balance.
Abnormal urinary potassium levels can indicate various conditions. Low urinary potassium may be seen in cases where the body is conserving potassium, such as dehydration or certain hormonal disorders. High urinary potassium may suggest excessive loss due to kidney disorders, diuretic use, vomiting, or hormonal imbalances like hyperaldosteronism. Doctors often use this test to investigate abnormal blood potassium levels and assess kidney handling of electrolytes.
The test requires a urine sample, either random or collected over a 24-hour period. Accurate results help doctors diagnose electrolyte imbalances, evaluate kidney function, and guide appropriate treatment to maintain overall health.
