Is a random or 24 hour urine collection more accurate? Why?

Answer 1

Yes, but it depends on what the doctor is looking for. It is the best tool for mojitoring kidney function-Glomerular Filtration Rate and for checking Creatinine Clearance. Both of thesse test require collecting urine for 24 hrs to provide a volume as well as
chemistries tested on the urine, volume is a large part of telling how the kidneys are working. Hope this helps.
