High Urine Creatinine Levels
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
My lab results show high levels of protein in urine 27 mg, urine creatinine 316.3 mg but levels of protein/creatinine ratio 90 mg. What does it mean?
Ur Protein/Cr ratio: The urine protein to urine creatinine ratio is an estimate of the 24hr urine protein. It is less cumbersome and quick. A urine protein to creatinine ratio of 0.15 or less would be consdered normal. For example urine protein of 30 and urine creatinine of 300 would be a upc of 0.1. ...Read more
My lab results show high levels of protein in urine 27 mg, urine creatinine 316.3 mg but levels of protein/creatinine ration 90 mg. What does it mean?
Protein in urine: The results mean that you probably have a lot of protein in your urine. To determine how much, you need to see a nephrologist and have a 24 hour urine collection to assess the amount of protein in your urine as well as your renal function. Depending on the amount of protein in your urine, you may need to have additional blood tests to see if you have any type of glomeulonephritis or diabetes. ...Read more
We have been told urine creatinine level of 3.3, calcium 2.4 is not good for 5 yr. Old, is this in normal range or elevated? What is norm range? Confused
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 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
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
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
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 ›
C prior answers: The random urine creatinine can give an approximation of urine function. Vma. .. Perhaps you are referring here to chemical in the urine when, if high, may indicate an tumor known as pheochromocytoma, which is benign, but produces a substance which can cause huge increases in blood pressure, that can have serious consequences. ...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
Why is it so hard to find out normal urine creatinine and calcium levels for a 5 yr old if 3, 3 creatinine, 2.4 calcium. What is norm? Shud I worry?
Worthless number: The total creatinine put out varies primarily with the total mass of skeletal muscle. You'll never find a "normal" value for either. The concentration is even more variable as it depends on how much water was drunk. The urine creatinine is measured only as something to compare with a semi-constant, the creatinine. People aren't numbers, and we do a disservice focusing on labs apart from history. ...Read more
Urine protein randm: 11.7, urine creatinine randm: 304 high (ref 58-161), protein/creatinine ratio: 38.44. What does tht mean? Do I need more test?
You have proteinuria (p) and the first thing is to have a 24 hour urine collection to see the amount of protein in your urine and to assess your kidney function. Have a renal ultrasound to assess kidneys' size
depending on the p, I would send off blood for aso, anca 2, complement C3 and c4, hiv, hepatitis b antibody to see if a cause could be found for the p, if not a kidney biopsy may be needed. ...Read more
Low rbc, high urea nitrogenBUN, high urine osmolality, high urine creatinine random, high UA sodium random, ab. Urine epithelial cell, k etones, ur. Mucus?
Dehydrated: 39 F from Indy of unknown ethnicity medical or drugs notes low rbc high bun and high urine Na creat. ANS: sounds like anemia and dehydration or renal disease. The latter is often due to eating too much salt and HTN and choosing the wrong grandparents. Your Dr knows you best so ask them. ...Read more
Should I be concerned with an Urine Creatinine level of 518.5 mg/dL, but I was dehydrated at the time of the test (just finished running 3 miles)?
Is 3822.00 mmol/l normal 24- hour urine creatinine? Is 200.1ug/24h normal cortisol level for 24 hour urine test?
Normal urine creatinine (24-hour sample) values range from 7-21 mmol/day (males) and 5-16 mmol/day (females). Results depend greatly on your age and amount of lean body mass.
Normal urine 'free' cortisol (24-hour sample) is usually less than 50 ug (=mcg). ...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
Yes: Urine creatinine means nothing in any case. It's secreted at a constant rate in proportion to your muscularity. It's merely a reference value to which you compare other analytes. ...Read more

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

Random urine chemistry:-urine creatinine=10.5mmol/l. Acr (microalbumin//creatinine ratio=1.0mg/mmol is it ok?

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 more
I had a 24hour urine creatinine test cancelled. Reason given on report was "antigen positive". What does this mean?
Uncertain: This is an unusual/uncommon reason for cancelling a 24-hour urine creatinine test that I have not seen before. There are a variety of medications that can potentially affect this test but reason for "antigen positive" is unknown to me. I would suggest contacting your ordering physician (or lab) so as to get an explanation. ...Read more
