Possible causes of a higher creatinine level include:
- kidney damage or kidney failure.
- kidney infection.
- reduced blood flow to the kidneys.
- dehydration.
What do BUN and creatinine levels indicate?
Creatinine Test 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 causes elevated BUN and creatinine?
Dehydration generally causes BUN levels to rise more than creatinine levels. This causes a high BUN-to-creatinine ratio. Kidney disease or blockage of the flow of urine from your kidney causes both BUN and creatinine levels to go up.
What does BUN mean in a blood test?
Overview. A common blood test, the blood urea nitrogen (BUN) test reveals important information about how well your kidneys are working. A BUN test measures the amount of urea nitrogen that’s in your blood.
What are the symptoms when creatinine is high?
Elevated Blood Creatinine Level – Symptoms However, common high creatinine symptoms are extreme unexplained fatigue and/or lethargy, dehydration, reduced urine output and/or darkened colour of urine, swelling over feet, face, under the eyes, etc.
What lab test is BUN?
What does it mean when creatinine levels are 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 creatinine level is too high?
High creatinine levels can mean kidney damage or dehydration. A high creatinine level is typically anything over 1.3 (depending on age, race, gender, and body size). Certain conditions may cause a person to have higher than normal levels of creatinine.
What causes elevated BUN levels?
Creatinine and blood urea nitrogen, or BUN, are both nitrogen-containing waste products generated by muscular activity. Creatinine and BUN can be elevated because of dehydration, drug reactions, heart disease and surgery.
What does a high bun and creatinine ratio mean?
A high BUN to creatinine ratio may signal dehydration, while lower BUN to creatinine ratios could indicate kidney disease. BUN and creatinine readings both increase when your kidneys are not functioning properly.
What could be the reason for high creatinine and low bun?
Continued below…. A high bun creatinine ratio can also result from dehydration, in which case the correction is usually simply to drink more water. An abnormally low bun creatinine ratio can also indicate kidney damage, in this case from intrinsic causes.
What is a dangerous high bun level?
High BUN indicates increased protein breakdown, which is associated with decreased immune function. A study shows that patients with elevated BUN (> 20 mg/dl) have an increased risk of infection [R]. High BUN is associated with increased mortality in critically ill patients [R, R, R, R].
