Question 1

what does high creatinine in the urine mean?

Accepted Answer

Good question: 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.

Question 2

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

Accepted Answer

A few possibilities: 390.1 mg per dl is not high if the 24 hr urine volume is 400-500 ml. In this case you may have dehydration on the day of the collection.  Not necessarily on other days! if the urine output is larger, you either have a proportionally lager muscle mass or lab error. Heavy physical activity can increase urine creatinine too. In view of normal blood work, shouldn't worry about having kidney disease.

Question 3

what does it mean when random urine creatinine is high?

Accepted Answer

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.

Question 4

creatinine urine total and microalbumin ttl are normal but microalbumin/creatine is high 41.5mg (normal is below 30) what does this mean?

Accepted Answer

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, it would have helped to have the raw numbers. If the ratio is high due to low creatinine, that is not a problem.

Question 5

what does it mean when your microalbumin level in urine is high, your urine creatinine level is borderline high but your ratio is 16?

Accepted Answer

: It means you urine is too concentrated at the time of urine collection and you do not have ABNORMAL microalbuminuria which is defined as urine microalbumin/creatinine is less than 30. Please note that microalbumin is also present in urine of people with normal kidneys. Take care.

Question 6

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?

Accepted Answer

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.

Question 7

insurance blood/urine tests showed creatinine 1.3, positive/high hemoglobin and white blood cells 20 -- what does this mean?

Accepted Answer

Trouble!: this needs to be checked with your doc. ASAP

Question 8

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?

Accepted Answer

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.

Question 9

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?

Accepted Answer

Reassuring value: A urine protein to urine creatinine ratio of 0.9 is reassuring. It is an estimate of your 24hour urine protein... 90mg.  A 24hour urine protein value of less and 100mg is very reassuring.

Question 10

can high creatinine levels cause urine foam?

Accepted Answer

See details: Foamy urine usually indicates elevated protein in the urine more than an elevated creatinine.
