High bun and bun/creatinine ratio results so bad kidneys?

Most of time: Generally high BUN and creatinine go hand in hand in bad kidneys(chronic kidney disease)., and bun/creat ratio is 10-15 to 1 , however if ratio >20 may indicate superimposed second cause like dehydration or bleeding in gut. ...Read more

Kidney (Definition)

The kidneys are paired organs that lie on either side of the vertebral column. Part of their critical functions include the excretion of urine and removal of nitrogenous wastes products from the blood. They regulate acid-base, electrolyte, fluid balance and blood pressure. Through hormonal signals, the kidneys control the ...Read more

Do high creatinine levels mean renal failure?

Do high creatinine levels mean renal failure?

High creatinine: Serum c is dependent on the person's weight, race and age. You need to have a 24 hour urine collection for a creatinine (c) clearance determination to know what your renal function is. When the urine is returned, blood is taken for a c level. That is the sure way to know how serious your creatinine level is and what your true renal function is. ...Read more

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

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. ...Read more

Creatinine level is 1.3mg/dl (range:0.8-1.3)..bun/creat ratio normal,electrolytes all normal, uric acid normal, urinalysis all normal.. any concern?

No: At your age, kidney function is usually starting to drop of. And/or you may simply be physically fit and decently muscled. When I was lifting weights daily, I ran 1.7-1.8. I see you have hepatitis C and cirrhosis. See if you can get into one of these new studies with the meds that usually cure it. Best wishes. ...Read more

Low creatinine and elevated bun/creatinine ratio. Please explain?

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

Maybe/depends,,,: If you are a big person with a normal egfr, and BUN, you might have a high Creatinine due to a lot of muscle mass. However, if you are small, and of light build, you could have an issue, and so a more extensive work up would be needed, including review of your meds, if you are taking any.

Having said that, it would have been helpful to know the actual creatinine and eGFR values. If these are abnormal if would be prudent to consult a nehprologist so that a treatable entity is not overlooked. ...Read more

What creatinine levels indicate kidney problems?

Varies: Although serum creatinine is routinely tested when blood chemistry is ordered, it is not a standardized test (i.e. different labs will give a slightly different numerical values & direct comparison of values from such labs is not meaningful). Frequently, normal serum creatinine ranges from 0.8 to 1.3 mg/dl. However, other factors such as degree of hydration and the muscle mass of the patient. ...Read more

I am told my Glomerular filtration Rate is 57.6. Does this indicate Kidney disease? Creatinine is 1.0 BUN is 20 total Protein is 7.0 I am 55 w/f

GFR: Your Estimated filtration rate is borderline. This is not a problem itself. The important concern is whether disease exists that might be progressive. Serum creatinine of 1.0 is "normal". So is serum creatinine 1.1. However, creatinine relates to muscle mass. If you are small muscled as a. 55 yo woman, then creatinine of 1.1 or 1.0 may indicate some minor impairment in its excretion. ...Read more

Diabetic nephropathy: B"sd kidney failure is marked by elevation of creatinine. Microalbumin is a sensitive test for early kidney changes seen in diabetes and hypertension.

elevated BUN, elevated k+ , elevated chloride, normal creatinine, and decreased Co2. Could this indicate kidney failure?

Probably not: I need more information in order to optimally answer your question. However, at a glance, the best indicator of kidney function is creatinine clearance. BUN can be elevated from other processes. I would need to look at the lab report to confirm your impressions. You are too young to have CKD. You should review the labs with the doctor who ordered them. ...Read more

Confused my creatinine is low 0.28 but my bun cr ratio is high 28.6. I'm concern about my kidneys since i've been type 2 diabetic 22 yrs. Pls advise?

Dehydration: Creatinine is more sensitive than BUN in terms of assessing kidney function, although, the most sensitive would be GFR (glomerular filtration rate). Sometimes the high ration is seen in people who are dehydrated or have urea production increase such as liver cirrhosis. ...Read more

Low GFR: GFR below 60 for > 3 months may be an indication of chronic kidney disease. As cardiovascular factors (blood pressure, glucose, lipids) are a major cause of kidney disease, these should be controlled. GFR also reduces with age. ...Read more

Bun/creatinine ratio is very high in kidney infections?

Generally no: An elevated bun/creatinine ratio (>20) is usually suggestive of "dehydration" and improves with increased fluids. Unless the patient with a kidney infection is also fluid depleted (due to vomiting or diminished fluid intake), the bun/creatinine is not excessively elevated in this setting. ...Read more

Usually not: There are many other more common reasons for a child to have a higher than normal bun/creatinine other than kidney cancer. Some of these include: dehydration, medications, infections, and urinary tract abnormalities. It is important to find out the cause of the impaired kidney function so that it can be treated. ...Read more

Get answers: The most common cause of proteinuria above trace (which should usually be ignored) is orthostatic proteinuria. This must be ruled out first. How are you being treated? You need a specific diagnosis first -- ACE inhibitors, protein restriction or what-have-you isn't appropriate until you really know what's going on. Insist on a full explanation -- it's your absolute right as the patient. ...Read more

Ankle swelling kidney creatinine .68 bun 13 ratio was 19.1 which is close to high ratio does that mean kidney or heart issues?

Neither : The BUN and creatinine are normal and the ratio is not important in your labs. The numbers are as good as they get. A good physical exam and history is needed to determine the cause of your ankle edema. The numbers don't point to kidney disease and work up heart disease need to see your MD. ...Read more

I routinely have high urea nitrogen and bun/creatinine ratio blood test results. This combined with frequent peeing at night and puffy hands/face in the morning and occasionally during the day Make me wonder if I have a kidney problem. ?

Maybe yes...: ...but the answer depends on the numbers. Certainly these symptoms could go along with significantly abnormal kidney function, but it's the actual BUN and creatinine numbers that tell the story. Ask another question that includes those lab test results, as well as calculated creatinine clearance, if that was reported with the creatinine result. Or just ask your doctor. ...Read more
