Urine Creatinine Values
No such thing: We don't publish a reference range as people would worry. The more muscle mass you have, the more creatinine you put out daily. The level in turn is also a function of how much water you drink -- whether the urine is concentrated or dilute. And there's no illness for which increased or decreased production is a marker. If you do find a published range, ignore it. ...Read more
Urine is the product of the kidneys, which is produced to eliminate the waste products of metabolism, manage body fluid balance, &maintain acid-base balance. The blood is first filtered by the kidneys, and the composition of the resulting fluid is then altered depending on the body's needs. It is composed of mostly water, and breakdown products from blood cells impart ...Read more
Absolutely nothing: You're probably not a female bodybuilder and you drank a little extra water. I'm glad I could reassure you. ...Read more
Dehydration: It appears that you may have dehyrdated cauisng hypernatremic (hypertonic) dehydration. This occurs when the lost fluid contains less sodium than the blood (loss of hypotonic fluid). Relatively less sodium than water is lost. Please be sure blood glucose, sodium and chloride levels were normal. I would see your doctor and have the urine test repeated along with a urinary sodium level. ...Read moreSee 1 more doctor answer
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
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. The urine level might be especially high if you haven't been drinking lots of fluids lately, i.e. if the urine is relatively concentrated. In any case, this is a good sign, nothing to worry about. ...Read more

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
What means an urine-to plasma creatinine ratio > 200? My urine creatinine was 171mg/dl, serum creatinine 0.8mg/dl, ratio:213.
Nothing: This is a meaningless number that is primarily a function of how much water you were drinking. It's used to help calculate other labs. ...Read more
Kindly interpret: my random urine albumin: less than 5.0 mg/l, random urine creatinine: less than 15.0 mg/dl. What is my albuminl:creatinine ratio?
Check again.: These readings seem more like those in serum although they are far below normal levels for Albumin and above normal for creatinine. The normal levels are 3.5-5.0 g/dl and <1.5 mg/dl for serum Albumin and creatinine respectively. The urine protein levels are <150 mg/day and creatinine is 1.0-1.6 g/day. The normal range of urine output is 0.4-3.0 l/day. These are low normal at most so recheck. ...Read moreSee 1 more doctor answer
Creatinine Clearance test - creatinine 1.2 & result was 140 of 24hr urine creatinine clearance - scale 66 - 143 is this high or does it mean v good ?
Creatinine clearance: The results are normal. Don't worry!Get a more detailed answer ›
Urine creatinine 24hour is 18.5 (7.1-17.7mmol/d) and my urine protein 24hour is 0.14 (<0.15g/d), I have IgM k monocloncal protein in b2 what is this?
Stop worrying: Reference ranges are where most people fall; there's no reason at all to get upset about a trivially high creatinine on a test that is done only to make a ratio with the albumin, which seems quite normal, thanks. My own guess is that your physician is eager to reassure you, and i'd urge you to accept this. There's much good in your life & future -- keep your eyes there. ...Read more
