Question 1

what does a high bun/creatinine ratio reading mean?

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 2

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.

Question 3

what does a "high" (23) "bun/creatinine ratio" mean for an otherwise healthy person? worried. can't get good explanation from my doctor.

Accepted Answer

Dehydrated?: This all depends on the clinical context. But the most common reason someone would have a high bun/cr ratio on routine blood work if they are feeling otherwise fine is being mildly dehydrated. More concerning reasons include having a bleed into the stomach (which you would likely know about!) or anything that could cause the kidneys to not be getting enough blood to do their job.

Question 4

high bun and bun/creatinine ratio results. what does this mean?

Accepted Answer

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.

Question 5

what does it mean low creatinine levels and high bun creatinine ratio?

Accepted Answer

Muscle mass: Serum levels of creatinine depend on renal function, muscle mass and intake of muscles foods. A low creatinine level is of no consequence as long as you are not emaciated. Paralyzed, or have extensive amputations. High ratio just reflects low creatinine.

Question 6

what does an elevated bun/creatinine ratio 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.

Question 7

i have high bun and bun/creatinine ratio (normal creatinine). i also have high alt(sgpt). i understand the bun can come from high dietary protein, but what does the alt of 35 mean? should i reduce protein intake to lower bun?

Accepted Answer

: Chance of low volume at the time of blood test as the cause of high BUN is higher than high protein intake. If you eat less than 1.5 gm/kg of protein a day, you do not need to cut down the protein intake unless proteinuria is present or you're born with one kidney. ALT is a liver enzyme and high number means possible liver injury. However, ALT of 35 is borderline, nothing to concern.

Question 8

what does it mean if your creatinine level is too high 1.16 and your bun/creatinine ratio is very low at a 5?

Accepted Answer

Why do you ask?: Labs mean nothing in the absence of a clinical history. You might be a vegan bodybuilder. When I was lifting weights every day, my creatinine ran 1.6-1.8. The fellow-pathologists with whom I've discussed it think that reports generated by labs are causing overdiagnosis of renal disease (it's subscience -- "there's an adjustment for race because black people are more muscular.")

Question 9

what does it mean if your bun/creatinine ratio is high and your creatinine serum is low?

Accepted Answer

Hypovolemic or : It means that a person is either hypovolemic ( dehydration ) or is bleeding in the gastrointestinal tract.

Question 10

i've had a high creatinine of 1.09, 1.11, 1.13.my bun /creatinine ratio is 10. also i have high uric acid.what does this all mean?

Accepted Answer

Nothing: These creatinine levels minimally elevated and you're in late middle age. Probably they mean nothing. Please manage any blood pressure / glucose tolerance issues, evaluate whether you are taking any meds you don't need, and follow them.
