What Is The Most Reliable Test To Measure Kidney Function?

What is the most reliable test to measure kidney function? A fasting CMP measuring creatinine? Results seem to be based on hydration and if fasting for 12 hour without fluids also cause creatinine to increase is this reliable indicator? Should CMP be repeated with good hydration to be reliable?

the best way to measure kidney function is to have your GFR measured. this is similar to a ct scan and is the gold standard.
