What is elevated urea and creatinine?

An elevated urea and creatinine indicates the kidneys are not working (called renal failure). Although urea is filtered into the urine by the kidney, some of the filtered urea will get reabsorbed and reused by the body.

What does a BUN of 70 mean?

The normal BUN level is between about 7 and 21 milligrams per deciliter (mg/dL). Unless this level is greater than 60 mg/dL, it may not help your healthcare provider measure your kidney health. A better measure is the ratio of BUN to creatinine found in your blood.

What is a high urea level?

High urea levels suggest poor kidney function. This may be due to acute or chronic kidney disease.

What happens if urea level is high?

Uremia can lead to kidney failure when left untreated. Someone with uremia may have seizures, loss of consciousness, heart attacks, and other life-threatening symptoms. Some will need a kidney transplant. Kidney failure may also damage other organs, so untreated uremia can result in liver or heart failure.

What are the symptoms of high urea?

• extreme tiredness or fatigue.
• cramping in your legs.
• little or no appetite.
• headache.
• nausea.
• vomiting.
• trouble concentrating.

What is the normal range of creatinine and urea levels?

Normal creatinine clearance for healthy women is 88-128 mL/min. and 97 to 137 mL/min. in males (normal levels may vary slightly between labs). Blood urea nitrogen (BUN) level is another indicator of kidney function. Urea is also a metabolic byproduct which can build up if kidney function is impaired.

What is the normal range for creatinine clearance and Bun?

Normal creatinine clearance for healthy women is 88-128 mL/min. and 97 to 137 mL/min. in males (normal levels may vary slightly between labs). Blood urea nitrogen (BUN) level is another indicator of kidney function.

What does high levels of urea in the blood indicate?

High levels of urea in the blood are an indication that the level of nitrogen waste products in the blood is high. This occurs because the kidneys fail to filter out the wastes as they should and consequently there are high levels of urea and nitrogen in the blood and this is toxic for the body. Symptoms include – disorientation, fatigue

What does it mean when your urea nitrogen and Bun are high?

Urea nitrogen levels tend to increase with age. Infants have lower levels than other people do, and the range in children varies. Generally, a high BUN level means your kidneys aren’t working well. But elevated BUN can also be due to:
