Question 1

meaning of  bun/creatinine ratio?

Accepted Answer

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.

Question 2

what causes elevated bun/creatinine ratio?

Accepted Answer

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.

Question 3

what's the meaning of high bun/creatinine ratio?

Accepted Answer

See below: An elevated BUN with normal creatinine and a ratio of  [generally more than 18-20] occurs most commonly in dehydrated individuals and is not a sign of kidney damage.It may also occur in in certain other conditions like  bleeding in the intestines, artificial nutrition intravenously of Amino Acids and use of steroids.

Question 4

what means bun/creatinine ratio and elevated alt?

Accepted Answer

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.

Question 5

how can the bun/creatinine ratio show dehydration?

Accepted Answer

BUN/Cr > 20:1: Urea (BUN) is reabsorbed by the kidney; creatinine is not. In dehydration, as water decreases and urea is reabsorbed, the BUN rises. Eventually, the cr will rise, too (if dehydration continues), but it doesn't increase in magnitude as fast as the bun. The bun/cr ration is usually ~10:1...When it's greater than 20:1, this suggests dehydration.

Question 6

how can the bun/creatinine ratio indicate dehydration?

Accepted Answer

May be helpful: There are many causes of an elevated BUN or elevated creatinine, and the ratio between them must be interpreted in the clinical context of each specific patient. What is commonly referred to as "dehydration" usually causes an increase in the BUN to creatinine ratio, but other significant conditions may cause a similar rise and need to be considered, especially if there is an acute illness involved.

Question 7

how can the bun/creatinine ratio tell you have dehydration?

Accepted Answer

See below: An elevated BUN with normal creatinine and a ratio of  [generally more than 18-20] occurs most commonly in dehydrated individuals and is not a sign of kidney damage.It may also occur in in certain other conditions like  bleeding in the intestines, artificial nutrition intravenously of Amino Acids and use of steroids.

Question 8

on a metabolic workup, what does a low bun/creatinine ratio reading mean?

Accepted Answer

Maybe, kidney diseas: In prior answers, explained bun, creatinine, normal ratio, and high ratio. Low ratio means that the BUN is likely low or normal with relation to the creatinine, indicating that there is adequate blood or volume flowing to the kidneys, but the kidneys are impaired or disease in some way. Need a nephrologist - kidney specialist.

Question 9

how does the bun/creatinine ratio show whether or not you have dehydration?

Accepted Answer

BUN/Creatinine ratio: Blood urea nitrogen (BUN) is the breakdown of protein excreted via kidney. Creatinine is the muscle breakdown product also excreted by the kidney. BUN and creatinine can be measured by lab tests. Usually the BUN / creatinine ratio has to to be over 20 for a patient to be considered dehydrated or in "pre renal kidney failure.

Question 10

during a metabolic workup, what does a high bun/creatinine ratio reading mean?

Accepted Answer

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.
