What does it mean when random urine creatinine is high?

What does it mean when random urine creatinine is high?

This is normal: Creatinine is normally excreted in the urine. The concentration of creatinine by itself means nothing other than the kidneys are doing their job.

Blood creatinine will tell you better how well the kidneys are working. ...Read more

Urine (Definition)

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

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

Is a urine creatinine level of 2.04 mmol/L worrysome?

No: Creatinine in the urine is measured only to compare with other substances -- it's an estimate of whether your urine is concentrated or dilute. You may have drunk an extra glass of water. ...Read more

What is a normal urine creatinine level?

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

Should I be concerned about urine creatinine levels over 165 mg/dl and high protein levels?

Should I be concerned about urine creatinine levels over 165 mg/dl and high protein levels?

Depends: It depends how high the protein levels are when they were checked. High urine protein levels are often a marker of kidney disease. High blood protein levels can be seen in multiple myeloma. This is concerning, and I would ask your physician for additional information. ...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?

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?

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?

Proteinuria: 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

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)?

Urine creatinine: No - if this was a 24 hour level - expect 14-26 mg per kg for a male fo that would be on the low side. If it was a "spot" urine - its going to be off due to the dehydration from running. I would repeat it if needed when you haven't run and are hydrated. ...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

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. 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

What does high urine creatinine of 390.1mg/dl mean but everything else is normal?

What does high urine creatinine of 390.1mg/dl mean but everything else is normal?

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

I'm a 43 year old man and my urine creatinine was measured at 42.4 mmol/L. Is it in safe range?

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

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

What means an urine-to plasma creatinine ratio > 200? My urine creatinine was 171mg/dl, serum creatinine 0.8mg/dl, ratio:213.

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

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

How can I compute the 24 hr urine protein and 24 hr urine creatinine? Thanks, Doc!

Need more info: Need more information as to why you want to know. The answer depends on that, and I'm not quite sure if you mean "interpret" rather than "compute." For what reason did you have the test done? Remember, in regards to tests, numbers are just numbers - the context in which they exist is where the importance lies. Please discuss with your physician. ...Read more

ACR test morning sample - 17mg/dl microalbumin urine, Creatinine is 0.6 in blood. No bp issue or sugar.

Normal: The albumin/creatinine ratio (ACR) urine test is used to detect the presence of abnormal amount of protein (albumin) in the urine which is often an early sign of kidney disease and an important prognostic marker in pts with diabetes and hypertension and a risk factor for cardiovascular disease. Your results (ACR 17 mg/dl and serum creatinine 0.6) are indicative or normal kidney function. ...Read more

Not much: You're 55 years old and -- congratulations -- a recovered problem drinker. Unless you're especially fit or heavily-muscled, your creatinine may be a bit high and maybe your kidneys are getting old -- but this level is perfectly compatible with good health and if you had serious kidney disease, it would be a lot worse by now. Eat sensibly, stay fit and I bet your kidneys will last a lifetime. ...Read more
