High values High creatinine blood levels can be caused by: Serious kidney damage or chronic kidney disease. Kidney damage can be caused by a life-threatening infection, shock, cancer, or low blood flow to the kidneys. Dehydration.
What is normal creatinine clearance level?
Normal Results Clearance is often measured as milliliters per minute (mL/min) or milliliters per second (mL/s). Normal values are: Male: 97 to 137 mL/min (1.65 to 2.33 mL/s). Female: 88 to 128 mL/min (1.496 to 2.18 mL/s).
What is normal creatinine clearance in elderly?
In adults younger than 50 years, daily creatinine clearance is 20-25 mg/kg ideal body weight in males and 15-20 mg/kg ideal body weight in females. In adults older than 50 years, daily creatinine clearance decreases progressively owing to reduction in muscle mass.
What level of creatinine indicates kidney disease?
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. As kidney disease progresses, the level of creatinine in the blood rises. This test is a measure of how well the kidneys are removing wastes and excess fluid from the blood.
Is creatinine clearance the same as GFR?
Creatinine Clearance ( CrCl ) versus Glomerular Filtration Rate ( GFR ) Creatinine clearance ( CrCl ) is an estimate of Glomerular Filtration Rate ( GFR ); however, CrCl is slightly higher than true GFR because creatinine is secreted by the proximal tubule (in addition to being filtered by the glomerulus).
What is a normal EGFR for a 70 year old?
Following the classical way, we can assert that normal GFR values are largely over 60 mL/min/1.73 m2 in healthy subjects, at least before the age of 70 years. However, we know that GFR physiologically decreases with age, and in adults older than 70 years, values below 60 mL/min/1.73 m2 could be considered normal.
What is a normal kidney function for a 70 year old?
Age 40-49: 99 mL/min/1.73 m. Age 50-59: 93 mL/min/1.73 m. Age 60-69: 85 mL/min/1.73 m. Age 70 years and older: 75 mL/min/1.73 m.
