Meaning of  bun/creatinine ratio?

Defines kidney prob: 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 causes elevated bun/creatinine ratio?

What causes  elevated bun/creatinine ratio?

Many causes: Blood tests called BUN (blood urea nitrogen) and cr (creatinine) are often checked to help evaluate kidney function. The normal bun/cr ration is about 10:1 to 15:1. Some of the more common causes of an elevated bun/cr ratio are: dehydration, GI bleeding, increased protein intake, small amount of muscle mass, increased muscle breakdown. ...Read more
