why would a doctor ask you to fast before a kidney ultrasound?I only have one kidney and lupus and my doctor is just seeing how my kidney is doing because i have had increasing numbers of protine in my urine, but why would I need to fast??

iam guesing that because the food or liquids might mixs up with your urine giving wrong results

well i havent been asked to fast before..
but it would be so you dont have a load of food lest in your intestines,, because that covers part of the ureta on the scan :)
