What does an elevated bun/creatinine ratio mean?

What does an elevated bun/creatinine ratio mean?

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.

What means an elevated BUN to creatinine ratio of 24 if both BUN and Creatinine are individually normal? BUN: 17.7, Creat: 0, 75. Take many fluids. Txs

Elevated ratio: Hi Oskcar. You lab levels are normal and your ratio is high due to your low creatinine level. If you had a high BUN-creatinine ratio that was abnormal due to dehydration, your serum sodium and chloride would be high. You did not mention those values in your test results. Were they elevated? If not, you need not worry, if they were, ingest more fluids to reduce them and lower your ratio.

What means bun/creatinine ratio and elevated alt?

Renal and liver test: Alt-liver enzyme-c priors. 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 kidney disease per se, but reduction in blood flow or volume to kidney, like when on strong diuretic-prerenal.

Bun glucose and pH are low t protein dldl are high with elevated sed rate. What could this mean?

Bun glucose and pH are low t protein dldl are high with elevated sed rate. What could this mean?

Can't answer: Labs mean nothing apart from the history and physical exam. How high? How low? Reference ranges are set so that at least 5% of healthy folks fall outside. You need a good relationship with a competent physician who communicates, and you need to stop trying to match yourself with things you read on the internet. We can handle specific questions but can substitute for your personal physician.

What does high BUN 44 mean?

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.

What does a bun of 28 mean on labwork?

What does a bun of 28 mean on labwork?

Blood urea nitrogen: BUN (Blood urea nitrogen) helps to indicate kidney function. Usually 7 to 20 mg/dL is normal in adults.

What is the implication of elevated bun/creatin levels?

See details: Elevated levels of BUN and creatinine signify reduced kidney function. The higher the values, the more compromised the kidney function.

Bun level is 23h what does this mean?

Bun level is 23h what does this mean?

Need correct value: And units. All laboratory 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. Having said that, it would have helped to know the correct result. 23h is not the conventional reporting of BUN results. If it is 23 mg/dL, it is slightly above normal and you should discuss it with your doctor.

Bun creatinine low what does that mean?

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

What does low bun level mean mine is 5?

What does low bun level mean mine is 5?

Blood urea nitrogen: Or bun, is an indicator of kidney function, fluid balance, muscle turnover (breakdown and rebuilding). Normal BUN is between 7 and 20. A low BUN could be seen in a person with lower muscle mass or low muscle use (ex a paraplegic person) where there is less muscle turnover than in more active people. This could also suggest malnutrition. A low BUN could also be seen in liver failure, pregnancy.

What does bun/creatine ratio of 18 mean?

What does bun/creatine ratio of 18 mean?

Means normal kidneys: BUN (blood urea nitrogen) is a test for a number of certain chemicals in the blood. Creatinine is a specific chemical that is released from the muscles. These are filtered out by the kidneys into the urine. The ratio of 18 means 18 to 1 of BUN to creatinine ; it is normal. If the ratio is higher that means the circulation is not delivering blood fast enough to the kidneys. If the ratio lowers to 1.

How is elevated bun related to pneumonia?

How is elevated bun related to pneumonia?

Elevated BUN: Elevated BUN represents a strained kidney most likely secondary to dehydration. Pneumonia is a significant illness that often leads to fever and dehydration.

Bun creatin ratio is 31 what does that mean?

Bun creatin ratio is 31 what does that mean?

Nothing: Assuming you're otherwise well. Having a nice steak dinner can do this, since you metabolize protein into urea which is what BUN measures. Don't overfocus on your labs. They're meaningful only as a guide in a larger context of the entire person.

I have a bun creatine ratio of 24 1 what does that mean?

I have a bun creatine ratio of 24 1 what does that mean?

BUN:Cr: Could be normal for you depending on factors such as your level of protein intake. May indicate state of dehydration. In the absence of symptoms, it means a good overnight fast in preparation for your blood draw the following morning.

Low creatinine and elevated bun/creatinine ratioplease interpret?

Stop worrying: Low creatinine is never a health concern. Reference ranges are set so that a few percent of healthies fall outside on either end. The ratio can be up if you're a little thirsty or ate a protein-rich meal lately.

What does it mean if both bun & creatinine levels are good, but the ratio is high?

What does it mean if both bun & creatinine levels are good, but the ratio is high?

Actual values: All laboratory 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. Having said that, if both creatinine and BUN are normal you do not need to worry about the ratio.

Need numbers: It would help to have the actual numbers. The doctor who ordered these tests would be in a better position to advise as s/he knows your health status.
