Question 1

neurogenic bladder. can bun 74 creatinine 2.5 values improve with b12? it went down to 44/1.5.  does the ratio indicate azotemia or urinary retention?

Accepted Answer

Renal impairment: While those values suggest dehydration, you could have more than just a bladder problem such as poorly functioning kidneys (renal impairment). Ask you doctor if referral to a urologist is appropriate - sounds like it is. Hope this helps!

Question 2

bun creatinine low what does that mean?

Accepted Answer

Nothing: Ignore it. Reference ranges are set so that several percent of healthy people fall outside. It's not the "healthy range." best wishes.

Question 3

what does a bun/creatinine raion of 33 indicate?

Accepted Answer

Nothing: Like all labs, it is meaningless apart from the clinical context. Maybe you had a big steak dinner. Maybe you are a very slender young girl. Maybe you are dehydrated after running a marathon in the blazing heat. Maybe you are in shock or end-stage congestive heart failure or suffering a massive GI bleed. If you feel reasonably well, don't even look at your labs -- they'll just trouble you.

Question 4

hi dr. if normal range for bun/creatinine is 8-20 should i be alarmed if mine is 23?

Accepted Answer

Bun: It is common for bun to be mildly elevated and to normalize when the test is repeated. The BUN number can be temporarily increased depending on the body current state of hydration. Try hydrating a little a few hours before your next blood test.

Question 5

which pharmacokinetic process would be affected by elevated creatinine and bun levels?

Accepted Answer

Depends on drug: Many drugs are excreted by the kidneys and doses of those drugs need to be adjusted in people with elevated BUN/Cr.

Question 6

i have a high bun/ creatinine level (28) and a low creatinine level (0.5) .  should i be concerned or do something?

Accepted Answer

No: Low creatinine never means anything bad. Reference ranges are set so that a few percent of healthies fall outside arbitrarily. The ratio could be up if you ate a couple of burgers. You're physician's not worried. Stay physically fit and you'll probably have a long and happy life. Best wishes.

Question 7

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 8

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 9

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 10

does pain medication cause hi creatinine and bun?

Accepted Answer

Depends: Depends on what you are using or calling 'pain medication'.  The non-steroidal anti-inflammatory agents (like ibuprofen, motrin, aleve, (naproxen) advil and certainly cause this.
