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.

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. ...Read more

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. ...Read more
