BUN/Cr Ratio: The most common cause of a high blood urea nitrogen (BUN) to creatinine ratio is dehydration. A ratio over 20 indicates low intravascular volume. The BUN can also be elevated in people with a high muscle mass.

Dehydration: Is most common cause of high BUN with normal creatinine (therefore high ratio). Other causes can be high protein load in the diet, muscle injury or muscle breakdown (bun is formed by the breakdown of proteins). Whether to worry depends on how high the BUN is, and the circumstances when the test was drawn. Talk to the doctor who ordered the test for personalized interpretation.

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.
