Blood Urea Nitrogen (Bun) Test
High BUN: You need to have more than a blood urea nitrogen (BUN) value to determine you have chronic kidney disease. You also need a creatinine (c) level, at the very least. Your BUN level is a reflection of your protein intake and your state of dehydration. If you ratio of BUN to c is > 20:1, you may have been dehydrated. Ask your doctor for more information. ...Read more
Find cause: Treat the patient, not the number. High BUN can be due to something as simple as eating a steak dinner & then running a marathon & getting dehydrated. This is good for you & need not be treated. Or it can be the sign of kidney disease, which should be treated; there are a lot of them & you need to find which one. ...Read more
Probably not...: Doctors don't just treat numbers with medicine and need to know symptoms. At these number would most probably need dialysis and not just medicine alone. ...Read more
Are you sure?: Are you sure creatinine is 4? Or maybe. 4? If it is 4 then this is a medical emergency and you need to be seen by a Nephrologist (kidney doctor specialist) as soon as possible or ED if new. If this is the case there is nothing else we can recommend over this media to make that better since multiple things might be happening. You might even need emergency dialysis. If it is 0.4 then it is normal. ...Read more
What do you suggest if I'm aged 53 my blood urea level is 32 mgs and seram creatitine is 0.8 mgs is it normal?
Sounds okay: The urea nitrogen may be a wee bit up because you had a nice steak dinner. ...Read more
High BUN and pain: You should ask your question to the physician (p) who ordered the blood work on you allowing you to discover the fact you had a high bun. Your p knows your case best of all, including the level of your bun, and is in a better position to give you a meaningful answer to your question. ...Read more
Good kidneys: There is no need for concern due to low blood urea. As long as you are not emaciated or undernourished. ...Read more
Liver chemical: This is a measurement of a concentration of urea in the blood stream and is related to the health of the liver. If the liver is dysfunctional, the level - termed BUN - will rise. This is part of most blood screening tests. ...Read more
Accurate: However, occasional errors happen rarely. All labs undergo rigorous validation/inspection by a specialized agency called clia to be licensed. All labs in the us are periodically tested for accuracy. ...Read more
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.
The notable exception is when the creatinine goes up say by 20% to 1.2, but the BUN goes up *5 to 50. This strongly suggests a pre-renal state, commonly dehydration.
Mild elevations of BUN with normal creatinines aren't of concern. ...Read more
Hi, I want to understand what blood urea is and its range. If the levels are elevated what does it signify. Does it mean kidney problems. Thanks.
What's BUN?: BUN stands for blood urea nitrogen. Urea nitrogen is what forms when protein breaks down and it not used by itself to identify patients with kidney disease. BUN is elevated in cases of dehydration as well as kidney disease. Serum creatinine (C) is a better determinant of kidney function. If the BUN C ratio is > 20, the patient may be dehydrated. The normal range of B is 7-20 mg/dl. ...Read more
I'm 25 & my Lt. Kidney size is 9.7x5.3 cm and Rt. Kidney is 8.6x4.5 cm. Blood urea is 17.0 & S-Creatinine is 0.89.Is there anything wrong with Rt. Kidney?
Stop worrying: Kidneys are often of slightly different sizes. Your labs are fine and dandy. Relax and be thankful for good health. ...Read more
My friend's blood report says that the blood urea and creatinine are 68 and 13 resp. Which was 109 and 15 earlier. Do you consider it as an improvemnt?
Depends: Normal serum creatinine ranges from 0.8- 1.5 in many labs, however one should see the normal range in their lab report. If the creatinine doubles- eg 1 to 2, it implies 50% kidney function loss. Creatinine above 4' implies advanced kidney disease. First one must find out if this is acute kidney injury or chronic kidney disease. If it is acute, this may represent recovery. Must seek medical advice. ...Read more
A friend is 52yr, Asian & 224lbs. His albumin 34, cretanine 1.2, blood urea is 27.He is diabetic since years & is on meds. Are these figures in range. Help
Hi, I don't think the Albumin number is correct, I think it's 3.4 instead of 34, which is slightly low, so an Albumin/creatinine in urine could find out if there is any proteinuria due to hx of Diabetes. The creatinnie could be abnormal depending on his muscle mass, need to know the GFR.
But I would say the weight is the most disturbing number especially in patient with DM, needs to lose weight. ...Read more
Hello, my father aged 54yrs have blood urea - 118, creatinie - 7.3 (reports generated on 17th feb). Request you toplease advice.
Talk to the doctor.: These lab results are concerning for severe kidney dysfunction, but without more information or previous labs to serve as a reference point, I cannot say whether the kidney injury is acute or chronic and if it is stable, improved, or worsening. The physician who requested the blood test should be able to interpret the results. A nephrology referral is warranted. Best of luck to him! ...Read more
Adjunct only: If you truly have renal disease, evidenced by a seriously and consistently elevated BUN and creatinine, then your focus needs to be on scientific, modern, evidence-based treatment that will keep you off dialysis / transplant service. You're welcome to use the ancient plant-based medicines as adjuncts but keep your nephrologist informed. ...Read more
My stepfather is an alcoholic. He is having blood urea and some complications in the kidney. Can it be cured without dialysis?
Impossible to say: With the information you are giving. Dialysis is only needed when kidney failure is occurring and has become severe. Alcohol actually has relatively few complications in the kidney, but if severe liver damage is present, the kidneys can become compromised from toxins not taken out by the liver. Without knowing what kind of kidney problem he has, what creatinine and BUN are, cannot say much. ...Read more
My friend has blood urea of 27 mg/dl. He is diabetic and cretanine 1.2, microalbumin 34. Is it a cause of concern!! Pls advise.
Kidney disease?: You need to give me some more information. You have given his creatinine (C) and I need his age, race and weight. You can plug in those values in the Crockroft-Gault formula and get an estimated glomerular filtration rate (GFR). As he has protein in his urine (P), he needs to have a 24 hour urine collection for C clearance and P. That will give his actual kidney function and quantify the P he has. ...Read more
