Question 1

my creatinine levels are up do i need to be concerned?

Accepted Answer

Yes: Talk to your Dr. Creatine is a logarithmic scale, so small increases can mean big changes in kidney function. Provider who ordered test should be able to tell you if within OK range for you or if concerning increase, and what to try to improve it.

Question 2

i have a high bun/ creatinine level (28) and a low creatinine level (0.5) .  should i be concerned or do something?

Accepted Answer

No: Low creatinine never means anything bad. Reference ranges are set so that a few percent of healthies fall outside arbitrarily. The ratio could be up if you ate a couple of burgers. You're physician's not worried. Stay physically fit and you'll probably have a long and happy life. Best wishes.

Question 3

should i be concerned about my rising creatinine levels? in 3 years my values have went .67, .88 to now 1.1. my gfr is 62.

Accepted Answer

Yes: 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. Having said that, Your gfr is abnormally low and you should consult a doctor.

Question 4

what does a creatinine level test for? and what is the average range?

Accepted Answer

Kidney function.: Creatinine levels are indicative of the kidneys ability to excrete waste.  Normal creatinine should run around 1 but is affected by many factors and increases slightly with age.

Question 5

what is the "average" margin of error on a creatinine level test? i know this varies by laboratory, but there must be a general average.

Accepted Answer

Yes.: Protein in take, fluid status, other meds can affect creatinine along with lab variation.So also specific kidney disease.

Question 6

my gfr is 49 and my creatinine level is within normal levels at 12. do i need a second opinion as my gp does not seem to be concerned.

Accepted Answer

I'm not concerned: The GFR estimate derived from the spot creatinine is a crude estimate. Both the pathology and the nephrology community have expressed misgivings about this number being generated routinely at all. The lack of real science is showcased by a different adjustment being used by race "because black people are more muscular than white people." i think your gp's right to ignore it.

Question 7

husbands blood creatinine level is 1.18,  reference range is ( 0.50-1.20 mg/dl).  bun/cre ratio is 11.0, range is (10-20 ). is there anything to be concerned about here?

Accepted Answer

No: You are reporting normal test results. There is no concern about this.

Question 8

should i be concerned about  urine creatinine levels over 165 mg/dl and high protein levels?

Accepted Answer

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.

Question 9

my creatinine level and bun are normal.  my gfr is lower than last year (50).  i am caucasian.  should i be concerned about kidney function?  thanks.

Accepted Answer

Yes.: GFR is very accurate as to evaluating renal function. It is derived from your BUN and Creatinine Levels but includes other factors. 50 is marginally low. It could indicate early renal disease. See an internist or nephrologist.

Question 10

i'm 28 year old male (74kg, about 8% body fat,  lifting weights 5times/week, on protein diet). my creatinine level i 109 umol/l, should i be concerned?

Accepted Answer

No worries: This is within the normal range for a male of 60-110 umol/l.  Higher muscle mass typically gives a higher level.  Stay well hydrated and you'll be fine.
