Overview

The Complete Kidney Function Panel is a thorough blood test designed to evaluate kidney health and function by measuring levels of waste products, electrolytes, and filtration rates. This panel assesses creatinine, urea, electrolytes (sodium, potassium, chloride, bicarbonate), and calculated ratios and rates to detect impaired kidney function, electrolyte imbalances, dehydration, or acid-base disturbances. Kidneys play a vital role in filtering waste, regulating fluids, and maintaining electrolyte balance, and early detection of issues can prevent progression to chronic kidney disease, which affects millions worldwide.
