Creatinine Serum creatinine levels provide a more sensitive measure of renal damage than do blood urea nitrogen levels. Creatinine is a nonprotein end product of creatinine metabolism that appears in serum and amounts proportional to the body’s muscle mass.
The blood urea nitrogen or BUN is a blood test that measures the amount of urea nitrogen in the bloodstream. It reflects how well your kidneys are. When a person is dehydrated, false results might be obtained as BUN levels increase when blood is concentrated. Elevated BUN levels indicate dehydration, excessive protein intake and impaired renal function. Low BUN levels indicate over hydration, liver damage and malnutrition.
Creatinine is a waste product produced by muscle metabolism. Kidneys filter creatinine to be excreted through the urine and the renal function is reflected. Elevated levels indicate renal impairment. The opposite happens for urinary creatinine clearance; during renal impairment, urinary creatinine is extremely low. Measuring urinary creatinine clearance during unilateral kidney impairment is insignificant as the healthy kidney can still excrete creatinine through the urine.
Blood Urea Nitrogen (BUN) The blood urea nitrogen (BUN) test is used to measure the nitrogen fraction of urea, the chief end product of protein metabolism. Formed in the liver from ammonia and excreted by the kidneys, urea constitutes 40% to 50% of the blood’s nonprotein nitrogen content. BUN level reflects protein intake and renal excretory capacity.
Ammonia is a waste product produced during the synthesis of protein. The liver converts ammonia into urea so it could be excreted out of the body. When there is an abnormally high ammonia levels in the blood, liver impairment should be suspected. In preparing for ammonia plasma test, the person being tested should refrain from smoking several hours prior to the test. Potassium salts, antibiotics and alcohol may also alter ammonia levels in the blood.
Sodium and chloride are the two important electrolytes in maintaining body fluid balance. Normal sodium range is between 130-145 mEq/L while chloride is between 95-100 mEq/L. Correct levels of sodium and chloride in the blood help in maintaining normal osmotic pressure, acid-base balance and nerve impulses.
How is the condition with creatinine 1.8 and blood urea 119? Here we will introduce the normal creatinine level and blood urea level, and how to help lower high creatinine and blood urea well, hoping useful and helpful for you.
