Is a BUN creatinine level of 11 bad?
The ideal ratio of BUN to creatinine falls between 10-to-1 and 20-to-1. Having a ratio above this range could mean you may not be getting enough blood flow to your kidneys, and could have conditions such as congestive heart failure, dehydration, or gastrointestinal bleeding.
What is normal range for BUN and creatinine?
Reference Range:
| Analyte | Male | Female |
|---|---|---|
| BUN, 0-18 Years | 5-18 mg/dL | 5-18 mg/dL |
| BUN, ≥19 Years | 8-23 mg/dL | 8-23 mg/dL |
| Creatinine, ≤2 Days | 0.79-1.58 mg/dL | 0.79-1.58 mg/dL |
| Creatinine, 3-27 Days | 0.35-1.23 mg/dL | 0.35-1.23 mg/dL |
Which is more important BUN or creatinine?
The best, although indirect, measure of kidney function is indeed the creatinine, not the BUN. Blood, urea, nitrogen is used by nephrologists often to determine whether or not the patient is dehydrated. Generally speaking, the relationship between your creatinine and BUN is 1:10 relationship.
Is 0.9 creatinine level normal?
Here are the normal values by age: 0.9 to 1.3 mg/dL for adult males. 0.6 to 1.1 mg/dL for adult females. 0.5 to 1.0 mg/dL for children ages 3 to 18 years.
What is the normal range for BUN?
In general, around 6 to 24 mg/dL (2.1 to 8.5 mmol/L ) is considered normal. But normal ranges may vary, depending on the reference range used by the lab and your age. Ask your doctor to explain your results. Urea nitrogen levels tend to increase with age.
What does low BUN creatinine ratio mean in a blood test?
A low BUN-to-creatinine ratio may be caused by a diet low in protein, a severe muscle injury called rhabdomyolysis, pregnancy, cirrhosis, or syndrome of inappropriate antidiuretic hormone secretion (SIADH).
What does a BUN of 8 mean?
Note that BUN values remain within the normal range until more than 50\% of renal function is lost. Within that range, however, a doubling of the values (e.g., BUN rising from 8 to 16 mg/dl) may mean a 50\% fall in kidney function [2].
What is the normal range of bun for kidney failure?
What level of BUN indicates kidney failure? The normal range of blood urea nitrogen (BUN) is between 7 and 20 mg/dL or 2.5 and 7.1 mmol/L. There may be slight variations between labs. A decline in kidney function can cause an increase in BUN levels. There is no definite value of BUN that would diagnose kidney failure.
What is the BUN/creatinine ratio?
So to recap, BUN levels fluctuate, while creatinine is removed at a constant rate and its blood levels are usually stable. That’s why the BUN/Creatinine ratio can be used to check for issues such as dehydration, kidney injury/disease, gut bleeding, and other problems [ 3 ]. BUN/Creatinine Ratio Normal Range
What is the difference between creatinine and EGFR?
Your creatinine level is used to estimate your eGFR. The good news is, there is a lot you can do to slow a kidney problem. To learn how to take action, read about How to Protect Your Kidneys. Your eGFR is a measure of how well your kidneys are working. It is estimated based on your creatinine level, age, race, and whether you are a man or a woman.
What is the normal range of EGFR for kidney failure?
Healthy people have an eGFR of 90 or higher. Most people don’t find out that they have CKD until they reach stage 3 or 4—or even 5. Kidney failure means that the eGFR is 15 or less. This is also called “end-stage renal disease,” or ESRD. To learn about treatment options for kidney failure, visit the Treatment Room.
