High bun and bun/creatinine ratio results. What does this mean?

High bun and bun/creatinine ratio results. What does this mean?

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. ...Read more

What does an elevated bun/creatinine ratio mean?

What does an elevated bun/creatinine ratio 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

Elevated creatinine serum what is critical?

Elevated creatinine serum what is critical?

Diagnosis needed: Serum creatinine is affected by protein intake, gender, age, race, muscular build, and renal function. A rising creatinine is always of concern. "normal" on lab tests is generally less than 1.2 mg/dl. Renal function can be estimated with a more complex formula or measured with a 24 h urine collection. See your internist for further evaluation. ...Read more

What does low bun level mean mine is 5?

What does low bun level mean mine is 5?

Blood urea nitrogen : Or bun, is an indicator of kidney function, fluid balance, muscle turnover (breakdown and rebuilding). Normal BUN is between 7 and 20. A low BUN could be seen in a person with lower muscle mass or low muscle use (ex a paraplegic person) where there is less muscle turnover than in more active people. This could also suggest malnutrition. A low BUN could also be seen in liver failure, pregnancy. ...Read more

What does a high bun and creatinine reading indicate?

What does a high bun and creatinine reading indicate?

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
