Elevated Urine Creatinine Level With Lupus
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
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 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
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 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)?
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 moreSee 1 more doctor answer
Is 3822.00 mmol/l normal 24- hour urine creatinine? Is 200.1ug/24h normal cortisol level for 24 hour urine test?
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 moreSee 1 more doctor answer
I have lupus -but my doctor never checks me urine ;but she does a cbc, cmp, esr, complements, cpk, bun, and creatinine. Should i be concerned w/ no ua?
Urine in lupus: Lupus is known to affect the kidneys, however, not in every patient. If there is a concern that your kidneys are affected, you doc should check your urine. It sounds she checks your kidney function by way of creatinine, so she monitors kidney function already. If you have any symptoms related to your kidneys - frequency, urgency, bloody/cloudy urine you need to bring them up to your doc. ...Read more
