What is a bun test?

Blood Urea Nitrogen: It is a test which identifies the breakdown products of urea in your blood. Urea is itself a breakdown product of proteins so that the BUN is an indirect measure of protein metabolism. BUN is elevated in kidney dysfunction, fever, increased catabolism, high protein diet and intestinal bleeding. ...Read more

I'm 63 female and my bun was 9 on my kidney test is this something to be concern?

I'm 63 female and my bun was 9 on my kidney test is this something to be concern?

BUN of 9: Your BUN of 9 is normal and it is also a reflection of your protein intake. Your serum creatinine is a much better guide to help assess your kidney function. If it is not elevated, you probably have reasonable kidney function. Serum creatinine is dependent on age, muscle mass, sex and race. ...Read more

Recent blood test showed my bun at 18 and my creative at 1.02 both on high end of range, should I be worried?

No: If you are a muscular male, these results would be right in the normal range. As it is the results are within normal limits. However, 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. See this site for more info.

My 5 month old son has mcadd. His test showed that his ck levels is 305 and his bun/creat ratio is 35.7. What does that mean?

Blood work: Your son has mcadd. He has an enzyme deficiency. Your doctor ordered blood work to look at his ck or creatinine kinase level from muscle and his blood urea nitrogen (bun) to creatinine (Creat) level. These are lab values your doctor is going to discuss with you. The bun/cr is a marker for kidney function. ...Read more

Recently got a blood test and had a bun level of 6.0 mg/dl and b/c ratio is 6.6. They said they were low. Should I be concerned?

Recently got a blood test and had a bun level of 6.0 mg/dl and b/c ratio is 6.6. They said they were low. Should I be concerned?

BUN of 5: Your BUN of 6 mg/dl is low. It is important to know that its level varies from lab to lab. And it is related to your protein intake and your state of hydration. You did not give your creatinine (c) level. Your c is dependent on your sex, age, weight and age. If the physician (p) who ordered the test is not worried, as he did not call you, do not worry about it. If you need reassurance, call the p. ...Read more

Renal: This fluctuation can be explained by change in fluid status. You do have hypertension, but if controlled that should not effect your renal function in a month. If feeling OK I would not worry about this. If concerned I would wait atleast a month till I recheck it. ...Read more

Blood tests for BUN 2 months ago was 23 high. Today it is higher 27. Also the GFR was 87. Today is 77. Creatnine was abnormal but today normal. Is it KD?

Abnormal gfr: It shows mild decrease of the kidney function. It could be some sort of damage to kidney or it could be just dehydration. If it is the case the values can return to normal after you get hydrated. See a nephrologist. May need more test. ...Read more

I had blood test done at er everything came back normal but what is b/cr test it was 6.2 and A/G was 1.0 should I be worried and my bun is 5 mg?

Both in normal range: Bun and creatinine are common blood tests used to measure kidney function. The ratio is typically around 10 for normal. The ratio can go above 20 in various conditions such as dehydration or intrinsic kidney problems. The albumin/globulin ratio is also in the normal range. Which is a non specific test to determine the different types of proteins in your blood including antibodies. ...Read more

Hi in my cmp test says bun/creatinine ration not applicable? What does it mean? Bad or good?

Hi in my cmp test says bun/creatinine ration not applicable? What does it mean? Bad or good?

Means not done: Not important. BUN & creat are what you need to have normal. It could be because one of the numbers is reported as "less than" e.g. BUN < 5 (less than 5). In this case you cannot calculate the ratio since you cannot use 5. The issue is not important anyways. You do not seem to have a kidney disease. ...Read more

Creatinine serum 1.5 mg/dl gfr 47-nb bun test 27 how bad is this. Can there be ways to improve on these results. Thank you?

Big picture: Everybody's kidney function declines some with age. I'm good with your BUN especially if you eat a lot of protein. And if you're a mature athlete, this may even be fine; creatinine varies with a man's muscularity. When I was lifting weights daily in my early thirties, my creatinine run 1.5 to 1.6 -- perfectly healthy. ...Read more

I have neprhocalcinosis, today I had a renal function test done and my BUN was 7 & chloride 112, other levels normal. What could this mean?

I have neprhocalcinosis, today I had a renal function test done and my BUN was 7 & chloride 112, other levels normal. What could this mean?

Labs: Your BUN is lower and maybe a reflection of your protein intake but doesn't mean disease. BUN levels are governed by many reasons including kidney function protein intake liver issues. Assuming you have no issue low BUN is more diet. Your chloride is high normal and should be repeated. These labs have to be looked in totality and don't mean disease. Best of luck ...Read more

Test results! Bun=6 /hematocrit=34/hct ic =35.1. Is these normal results? The paper I was given shows these are below normal but dr said they were ok

What's "normal"?: Reference ranges are set so that several percent of healthy folks fall outside on either end. "normal" doesn't necessarily mean "healthy" in any case. Especially, low BUN in a person who looks and feels well never means anything. Your physician gave you good advice. ...Read more

Is it possible to eat a muffin with poppy seeds or a bun with sesame seeds and test positive on a urine test? Had a friend claim it happened to them.

Is it possible to eat a muffin with poppy seeds or a bun with sesame seeds and test positive on a urine test? Had a friend claim it happened to them.

Even: Even though the drug, opium, is from a different part of the poppy plant, there is a possibility of failing a drug test after eating poppy seeds. It was actually tried on a myth busters episode and has been written about on snopes. Com (see below)! luckily, many tests have taken this into consideration, so will only register much higher levels of opiates as an actual "positive" on a drug test than you can get from eating poppy seeds. Good luck! ...Read more
