What Does Elevated Bun Mean
Decrease in flow.: Bun=blood urea nitrogen, byproduct of proteins ingested, if rise to high levels due to kidney problem, can cause toxic affects on the body. Creatinine= measurement of renal function. Normal bun/cr ratio about 10. The higher that ratio, the more likely it is not intrinsic kidney disease per se, but reduction in blood flow or volume to kidney, like when on strong diuretic-prerenal-reversible. ...Read more
What means an elevated BUN to creatinine ratio of 24 if both BUN and Creatinine are individually normal? BUN: 17.7, Creat: 0,75. Take many fluids.Txs
Elevated ratio: Hi Oskcar. You lab levels are normal and your ratio is high due to your low creatinine level. If you had a high BUN-creatinine ratio that was abnormal due to dehydration, your serum sodium and chloride would be high. You did not mention those values in your test results. Were they elevated? If not, you need not worry, if they were, ingest more fluids to reduce them and lower your ratio. ...Read more
Renal and liver test: Alt-liver enzyme-c priors. Bun=blood urea nitrogen, byproduct of proteins ingested, if rise to high levels due to kidney problem, can cause toxic affects on the body. Creatinine= measurement of renal function. Normal bun/cr ratio about 10. The higher that ratio, the more likely it is not kidney disease per se, but reduction in blood flow or volume to kidney, like when on strong diuretic-prerenal. ...Read more
What does having elevated total bilirubin (1.1) but low BUN (4) mean? AST was also flagged as low but I have read that isn't significant.
All ok: All these data are essentially normalGet a more detailed answer ›
Can't answer: Labs mean nothing apart from the history and physical exam. How high? How low? Reference ranges are set so that at least 5% of healthy folks fall outside. You need a good relationship with a competent physician who communicates, and you need to stop trying to match yourself with things you read on the internet. We can handle specific questions but can substitute for your personal physician. ...Read more
What can cause to have bun/creatinin ratio elevated. My test resul bun 18 norma 6-20, creatinin 0.63 norma0.57-1 and bun/creat ratio 29 norm 35-155?
Need correct value: and units. 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 helped to know the correct result. 23h is not the conventional reporting of BUN results. If it is 23 mg/dL, it is slightly above normal and you should discuss it with your doctor. ...Read more
