How does the bun/creatinin ratio relate to the egfr? Both of these levels are low but both the bun and creatinin levels were right in the mid range.

Co-tango usually: The BUN is usually 10 times the creatinine. When the creatinine goes up, the BUN goes up similarly to roughly keep this proportion, in most kidney disease states. The notable exception is when the creatinine goes up say by 20% to 1.2, but the BUN goes up *5 to 50. This strongly suggests a pre-renal state, commonly dehydration. Mild elevations of BUN with normal creatinines aren't of concern. Read more

My creatinine levels were flagged at 1.18 my bun was normal at 11 and my eGFR was 68 normal for African American I am 37?

You're fine: As a pathologist, I join many of my friends in nephrology in thinking that these "estimated GFR's" are subscientific rubbish intended to get people to take Big Pharma pills they don't need. The racial stuff was actually introduced "because black people are more muscular." When I was lifting wieghts daily, my creatinine ran 1.6-1.7. You're not a kidney patient in my humble opinion.

I recently had blood work done and it indicated that my bun was high at 22 with egfr at 87 and bun/creatine level of 21. Should I be concerned?

Kidney function est: Estimating kidney function is just that, an estimate. There are a few ways to actually measure kidney function, but for most people an estimate by blood testing is adequate. Unfortunately the equations that report GFR are very very inaccurate in higher levels of kidney function. At my clinic we stop reporting the exact estimate and instead simply record it as 60+ as a way to reassure our patients. Read more

Regarding blood test-what is co2 is high, creatine is high, egfr is low, bun/creat ratio high?

Regarding blood test-what is co2 is high, creatine is high, egfr is low, bun/creat ratio high?

Lab results: The lab results you mention, low creatinine high and egfr is low are consistent with a person with chronic kidney disease. The co2 in chronic kidney disease is not high and can be low. The high bun-creatinine ratio is suggestive of a dehydrated state. Please provide the actual numbers of the lab values you stated for a better answer. Read more

My bun/creatinine ratio is low and my egfr non african american is low (57.4) the urine itself was normal but dark and cloudy. What's going on?

My bun/creatinine ratio is low and my egfr non african american is low (57.4) the urine itself was normal but dark and cloudy. What's going on?

I'm not worried: This isn't science. The adjustment for race is there "because black people are more muscular than white people". BUN/creatinine ratio being low is never a problem if you feel even semi-well. Dr. F. has given you good advice. Just keep an eye on this and if your actual creatinine is up well above reference range for a time, get evaluated. Read more

Does this mean kidney disease? Any reason for co cern? High creatinine low egfr normal bun

Does this mean kidney disease? Any reason for co cern? High creatinine low egfr normal bun

How high?: 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, it would have been helpful to know the actual creatinine and eGFR values. If these are abnormal if would be prudent to consult a nehprologist so that a treatable entity is not overlooked. Read more

Listen Charlie: Please forgive me. I'm a pathologist focused on lab medicine. Labs mean NOTHING in the absence of a history and physical exam. And labs are not simply "high" or "low". These may be the labs of a bodybuilder with hookworms, or a man gravely sick. All I know is that if your physician won't sit and explain your labs -- and these worry me greatly -- get with some else.

**BUN/creatinine level is 54.7**??? urea nitrogen is 29, creatinine is 0.53, eGFR is 128, potassium is 4.4. Cause for concern? I literally cannot find anything anywhere about a BUN/creatinine level that high.

BUN/GFR 54.7: I would not worry. It is a ratio-calculated value. Your BUN is 29 (normal < 20) but that could be due to either mild dehydration or high protein in body (unless you are actively bleeding). Your creatinine is 0.53 which is great. The ratio is BUN/Cr 29/0.53 = 54.7. Your GFR another number we look seriously at is 128 great, potassium is 4.4 normal. Do not worry it is an artifact of the math Read more

My 2007 med record says: glucose 104, bun 25, creatinine 1.5, bun/creat ratio 17, egfr 58. Any danger in any of those, I'm scared :- (

My 2007 med record says: glucose 104, bun 25, creatinine 1.5, bun/creat ratio 17, egfr 58. Any danger in any of those, I'm scared :- (

Of what?: This is from 2007, which is 6 years ago and therefore of limited significance. Newer results are needed. Your creatinine is very slightly high for someone your age, but may have been falsely elevated due to dehydration. Don't be afraid, go get more current results and discuss them w/your doctor.

Recent labs showed Creatine 1.05 and BUN 10 all other labs and Urine normal. The 1.05 is an year over year increase from. 89 putting my EGFR at 58?

Consult nephrologist: Your eGFR puts you at risk and you should consult a nephrologist to make sure that a treatable condition is not being missed. It is not feasible to provide a more meaningful opinion without an in-person evaluation. Read more

Bun is 28, creatinine 1.16. Egfr 61. Healthy 35 yr old caucasian female. Only problem is benign fasciculations x1 year. Normal creat kinase. Why?

Bun is 28, creatinine 1.16. Egfr 61. Healthy 35 yr old caucasian female. Only problem is benign fasciculations x1 year. Normal creat kinase. Why?

Stop worrying: I am going to assume that you feel well and are asking why your estimated GFR is lowish and your BUN a bit high. I like to eat protein and my BUN is always high. Are you athletic? When I was lifting daily my creatinine was 1.6-1.7; or a Motrin tablet or minimal kidney disease may be raising yours. I suggest repeat in a year and stop fretting over a number in the meantime.

Would getting a UTI cause the kidney numbers like egfr, bun, and creatinine to change for the worse?

Would getting a UTI cause the kidney numbers like egfr, bun, and creatinine to change for the worse?

UTI and EGFR: Normally, uti's have no effect on gfr. If you have some obstrction (o) in your urinary outflow tract, your GFR can decrease until the o is resolved. What was the time interval between your GFR readings? Call you doctor and get his advice or see a nephrologist for another opinion. Good luck. Read more

I had one more quick question. If bun 25, creatinine 1.5, bun/creat ratio 17, egfr 58...The egfr means im in stage 3 CKD right? 58% kidney function?

Stage 3 CKD: You are correct in that your estimated GFR of 58 ml/min puts you into stage 3 chronic kidney disease. Remember, your GFR is estimated. The actual result may be greater, or lower, than the egfr. To get your acutal gfr, have a 24 hour urine for creatinine clearance. Ask the physician who orders this test to have proteinuria (p) assess in that sample. If p is present, it may needed to be treated. Read more

Diabetic kidney: From your data, it appears that you clearly had some improvement in your egfr. The "e" stands for "estimated". You may had this recovery of renal function due to a reduction of the amount of protein (p) in your urine, or relief of some obstruction. Ask your doctor to send you to a nephrologist (n) to find out what your actual GFR is with a 24 hour urine for creatinine clearance and p collection. Read more

Creatinine of. 09 bun of 14 bun/creatinine ratio is 16 but cystatin c is 1.14 and eGFR is 66.... Do I have some kidney function issues Pcp not concern?

Forget it: The formulas used to estimate kidney function from spot creatinines are actually anti-scientific. They include an adjustment for race "because black people are more muscular." Creatinine where you have it is fine. Be glad for good health and ignore this stuff Read more
