The BMP includes the following tests: Kidney Tests: BUN (blood urea nitrogen): A waste product filtered out of the blood by the kidneys . An elevated BUN may indicate abnormal kidney function, liver disease, or heart failure. A low number may indicate malnutrition.
What does a high BUN level mean?
Generally, a high BUN level means your kidneys aren't working well . But elevated BUN can also be due to: Dehydration, resulting from not drinking enough fluids or for other reasons. Urinary tract obstruction. Congestive heart failure or recent heart attack.
Is a BUN and creatinine in a BMP?
The basic metabolic panel typically measures the serum or plasma levels of sodium, potassium, chloride, and bicarbonate in the body. The BMP is also used to test other electrolytes such as: blood urea nitrogen (BUN), creatinine, and glucose to check for or rule out diabetes or kidney disease.
What level of BUN indicates kidney failure?
If your kidneys are not working well, the urea nitrogen will stay in the blood. Normal blood contains 7-20 mg/dl of urea. If your BUN is more than 20 mg/dL , your kidneys may not be working at full strength. Other possible causes of an elevated BUN include dehydration and heart failure.
What are the symptoms of high BUN levels?
- Needing to go the bathroom (urinate) frequently or infrequently.
- Itching.
- Recurring fatigue.
- Swelling in your arms, legs, or feet.
- Muscle cramps.
- Trouble sleeping.
How can I lower my BUN level?

- malnutrition.
- severe lack of protein in the diet.
- overhydration.
Is a BUN level of 23 high?

Why would a doctor order a BMP?
The basic metabolic panel (BMP) may be used to check the health of your kidneys , the status of your electrolyte and acid/base balance, as well as your blood glucose level – all of which are related to your body's metabolism.
What does a BUN of 7 mean?
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 does a BMP include?

What is the creatinine level for stage 3 kidney disease?
Optimal cutoff values for serum creatinine in the diagnosis of stage 3 CKD in older adults were > or =1.3 mg/dl for men and > or =1.0 mg/dl for women , regardless of the presence or absence of hypertension, diabetes, or congestive heart failure.
Can drinking water reduce blood urea?
Results: Serum urea and folic acid concentration decreased up to 40% after administration of the water load in 24 hours. Serum creatinine concentration decreased up to 20% after administration of the water load in 30 minutes.
Where do you itch with kidney disease?
It can come and go or it may be continuous. It may affect your whole body or be limited to a specific area – usually your back or arms . Itching tends to affects both sides of the body at the same time and may feel internal, like a crawling feeling just below the skin.
