What does it mean when creatinine is low and bun creatinine ratio is high?
BUN and creatinine levels that are within the ranges established by the laboratory performing the test suggest that your kidneys are functioning as they should. Increased BUN and creatinine levels may mean that your kidneys are not working as they should.
What does it mean if BUN creatinine is low?
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).
Should I be concerned about a low bun creatinine ratio?
What does it mean if your BUN/Creatinine Ratio result is too low? A decreased ratio may be observed with liver disease and poor diet. Temporary levels that are high or low may not be a cause for concern and should be retested to confirm.
What if BUN is normal but creatinine is high?
Work with your doctor or other health care professional for an accurate diagnosis. A BUN/Creatinine ratio above the normal range can be caused by: Dehydration. Dehydration increases the blood levels of both BUN and creatinine but increases BUN more than creatinine [11].
What does a low BUN indicate?
Abnormally low levels of BUN can be a sign of malnutrition, lack of protein in the diet, and liver disease. Therefore, other tests included in a panel test like the comprehensive metabolic panel may provide helpful information for understanding the significance of low blood urea nitrogen.
Why would my creatinine be high?
Generally speaking, high levels of creatinine can indicate that your kidneys aren’t working well. There are many possible causes of high creatinine, some of which may be a one-time occurrence. Examples can include things such as dehydration or intake of large amounts of protein or the supplement creatine.
What’s more important creatinine or BUN?
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.
What level of creatinine indicates kidney disease?
Blood Tests A creatinine level of greater than 1.2 for women and greater than 1.4 for men may be an early sign that the kidneys are not working properly.
What is the difference between creatinine and BUN?
When your BUN levels are compared with your creatinine levels, it gives a fuller picture of what’s happening with your kidneys. This is known as the BUN/Creatinine ratio. Creatinine is a waste product from your muscles that is also filtered by your kidneys.
What does low BUN indicate?
What causes a high bun level?
– Congestive heart failure – Excessive protein levels in the gastrointestinal tract – Kidney disease – Kidney failure – Urinary tract obstruction – Gastrointestinal bleeding – Dehydration – High protein diet – Stress or shock
What does a high bun mean in a blood test?
Normal BUN levels vary, but high levels in your blood sample usually mean your kidneys aren’t working normally. They can be a sign of kidney disease or failure. Higher than normal BUN levels may also indicate dehydration, high-protein diet, medications, burns or other conditions. Your doctor tell you what your results mean.
What bun level is too high?
Once the GFR decreases below 15, one is at high risk for needing treatment for kidney failure, such as dialysis or a kidney transplant. Urea nitrogen comes from the breakdown of protein in the foods you eat. A normal BUN level is between 7 and 20.
How can you lower your BUN creatinine levels?
Liver Disease. Liver disease,especially severe liver disease,can lower both BUN and creatinine levels in your body.
