Q: what significance is an elevated bun/creatinine ratio? i also had wbc on urinalysis but no bacteria, no signs of uti. bun and creatinine individually

Better to look at: Actual results rather than the ratio. What are the results for BUN and creatinine? Please note that all lab results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that.

Q: what is normal for bun and creatinine post kidney removal? my grandfather's bun: 28 and creatinine: 2.05. he is 3 weeks post surgery.

No exact answer. But: This value ofcreatinine of 2 after removal of one kidney is not normal. It should be closer to 1.0 or so. However, if grandfather is in his seventies and about 160-170 pounds, his kidney function is near 50% or so. In his age group, his kidney function should be near 70% or so. He has probably an aging of his kidneys beyond his actual age. Need to ask his doc about reason. Hi blood pressure?

Q: increase of bun?

Kidney testing: BUN is elevated when one is not ill if the patient is fasting, is a bit dehydrated or has not eaten or drank much fluid before the test. It is rarely in and of itself a problem.

Q: age adjusted bun?

BUN: Normal range is 7-39 mg/dl; no adjustment for age is required.

Q: what does high bun 44 mean?

High BUN: May mean that you have kidney disease, or hemolytic anemia, or gastrointestinal bleeding, or stomach obstruction. Dehydration also can cause the level of blood urea nitrogen to be falsely higher. Thanks for trusting in HealthTap.

Question 1

what is bun/creat ratio my hospital range 12.0-20.0 mines was 10.5 so is something wrong with me?

Accepted Answer

Probably not: A 10:1 ratio is "normal", but there are a LOT of variable with this one.  Simply being dehydrated is the most common cause of increased ratios, but age, muscle mass, overall health, medications and gender all play parts.  I often caution both patients and students/residents to treat the patient, not the labs.  If you're otherwise healthy and take care of yourself, don't get too worked by numbers.

Question 2

what is a bun test?

Accepted Answer

Family practice : It stands for blood urea nitrogen. It is usually run with a creatine test to determine how your kidneys are functioning.

Question 3

what is a bun/creatinine ratio?  how is it calculated and if mine is 22 but my other levels are fine what should i do?

Accepted Answer

What are the actual: Numbers? BUN number divided by creatinine number. Normal range is 10-20.  22 may not be abnormal if individual levels of BUN and creatinine are normal. Discuss the numbers with your doctor at the next visit.

Question 4

what is a normal bun for a person with one kidney?

Accepted Answer

Co-tango usually: A patient with one kidney should have a creatinine less than 1.0 mg/dl still.  The BUN should be less than 10.  
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.

Mild elevations of BUN with normal creatinines aren't of concern.

Question 5

what is wrong when your bun level is up to 800?

Accepted Answer

Not feasible: Normal BUN is <20, a value of 800 would not be compatible with life. You probably have erroneous information.
