Why might it be that we use urine creatinine when caclucating GFR ?

Not reabsorbed: Creatinine is used to calculate glomerular filtration rates because the kidney does not reabsorb it: whatever gets filtered into the glomerulus ends up in the urine. So it is a reliable indicator of how much blood has been filtered. All you have to calculate is the volume of blood that contained the amount of creatinine that appeared in the urine over a certain time. ...Read more

Why would my blood creatinine be low and my urine creatinine be high?

Why would my blood creatinine be low and my urine creatinine be high?

Strong kidneys!: It sounds like your kidneys are working normally. That's what they're supposed to do -- clear metabolic products like creatinine from the blood, dumping it into the urine.

In any case, this is a good sign, nothing to worry about. ...Read more

Can eating lots of food like protein cause high urine creatinine?

Can eating lots of food like protein cause high urine creatinine?

Muscle is muscle: There is a trace amount of creatine and creatinine in muscle meats which contributes slightly to urine creatinine, but most of it comes from the production of creatine in your own muscle. Creatine is used for short term storage of energy as creatine phosphate and some leaks out of your muscles every day. After a loading dose of 25 g per day for a week, 5 g creatine per day helps muscles work. ...Read more

My urine creatinine was 20 when 4 months ago it was 73, my BUN level was 7. What could be causing this?

This means nothing: Urine creatinine varies with your hydration. You excrete a certain amount daily depending mostly on your muscle mass. Drink twice as much water, and you cut your creatinine in half. It's worth measuring only as a standard against which to compare other elements measured in your urine. A "low BUN" means nothing. You're not a kidney patient. I'm sorry no one explained this to you. ...Read more
