What does high creatinine in the urine mean?

Good question

Urine
Creatinine in the urine, like in the blood, comes from the muscles. The urine creatinine can be collected for 24 hours to calculate the creatinine clearance. A sample of urine creatinine and protein can be used to estimate the 24h urine loss of protein.

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

Creatinine
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

Protein in urine

Protein
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.

What exactly does it mean when a 67 years old male has 218 ummol/l level of creatinine in urine?

Nothing

Urine
this test can not be used without a serum creatinine value, urine volume and hours of collection also help. by itself it means only that creatinine is present in the urine.

Blood work says my ratio of albumin and creatinine is 59 what could this mean? I am worried about my visit tomorrow with urology. +pro in urine

Proteinuria

Creatinine
Protein crea ratio approximately tells us how protein may be there in a 24 hour urine sample. A random sample or urine protein divided by random urine crea. A value of .5 could mean there could be 500 mg in a 24 he samples and a value of 2 could mean 2 gms. A 24 hour urine collection is more appropriate. If there is proteinuria then you should be evaluated by a nephrologist.

Shud I be concerned with brown looking urine from my 5 yr old girl, who has had recent elevated creatinine level in urine? No diagnosis yet, Drs Mon

Brown urine

Creatinine
There are a number of causes of brown urine, that can reflect kidney, liver, blood or muscle disorders that need to be evaluated by medical tests (mostly blood-work, some urine tests). Preliminary tests might include urinalysis, CBC, retic count, CPK, ASO titer, C3,C4, CMP, Urine protein/creatinine ratio, ASO titer, etc. A pediatric nephrologist (kidney specialist) may be appropriate.

Dr. Jack Rubin answered:

Can I take Lisinopril, amlodipine, and furosemide for high creatinine and protein in urine, while I also have high uric acid levels?

Meds for proteinuria

Creatinine
Lisinopril (L) is an excellent drug for reducing proteinuria (P) and blood pressure control. With a high creatinine, you need to be under the care of a nephrologist (N) to make sure you can preserve your kidney function as long as possible. You also need to have a 24 hour urine collection to assess your kidney function and to see how much P you have. A N can also help with your uric acid problem.

Dr. Jack Rubin answered:

Creatinine level is 3.9, leukocytes 3-5, erthrocytes 10-12 protein ++ in urine. Could it be my medications?

High creatinine

Protein
You should see a nephrologist to get answer to your question. Some medicines, of the Advil class, can cause acute renal failure, which reverses once you stop taking them. Due to the presence of protein and blood in your urine, you need a 24 hour urine collection for creatinine clearance and protein. You also need some blood work to see if you have diseases that can cause proteinuria, diabetes?

WBC in urine 92/ul then 18/ul after 1 day. Will creatinine of 159 umol/L normalize after urinary tract infection has been treated?

Should

Urinary_tract
In some adults, recurrent UTIs may cause scarring in the kidneys, which over time can lead to renal hypertension and eventual kidney failure. Recurrent urinary tract infections, even in the kidney, almost never lead to progressive kidney damage in otherwise healthy women.
