In general, creatinine clearance is the removal of creatinine from the body. In renal physiology, creatinine clearance is the volume of blood plasma that is cleared of creatinine per unit time. Clinically, creatinine clearance is a useful measure for estimating the glomerular filtration rate (GFR) of the kidneys.1
Creatinine is a breakdown product of creatine phosphate in muscle, and is usually produced at a fairly constant rate by the body (depending on muscle mass).2
The result of this test is an important gauge used in assessing excretory function of the kidneys.1

Creatinine clearance is a measure of kidney function. Patients are on dialysis because their kidneys do not function properly thus their creatinine clearance would be very, very low. Some patients may have some residual kidney function but their creatinine clearance would be less than probably 10 ml/min.
The creatinine clearance test measures how well the kidneys are filtering waste products from the blood. It involves collecting urine samples over a period of time to determine the amount of creatinine excreted. This test is used to assess kidney function and detect any abnormalities.
Clearance is the volume of blood cleared of a substance per unit of time, usually measured in milliliters per minute. Creatinine clearance specifically refers to the rate at which the kidneys remove creatinine from the blood, serving as an indicator of renal function. It is a valuable measurement in assessing kidney health.
Low clearance values for creatinine and urea indicate a diminished ability of the kidneys to filter these waste products from the blood and to excrete them in the urine.
The glomerular filtration rate (GFR) cannot be directly calculated from urine creatinine clearance. However, assuming a constant relationship between GFR and creatinine clearance, a urine creatinine clearance of 30mL/min may correspond to a GFR of approximately 30mL/min. Further evaluation by a healthcare provider is recommended.
to find out kidney filteration rate.
Creatinine clearance is a measure of the kidney's ability to filter waste products, like creatinine, from the blood. It is calculated using a formula that takes into account a person's age, weight, and gender. The creatinine clearance value helps healthcare providers assess kidney function and determine appropriate treatments.
To increase creatinine clearance, you can stay well hydrated by drinking plenty of water, maintain a healthy blood pressure, and follow a balanced diet rich in fruits, vegetables, and lean proteins. Additionally, regular exercise and avoiding certain medications that can affect kidney function may help improve creatinine clearance.
Normal creatinine clearance in most people is over 60 mL/min, however, in pregnancy it is increased by as much as 50% because of increased GFR and renal plasma flow.
Low clearance values for creatinine and urea indicate diminished ability of the kidneys to filter these waste products from the blood and excrete them in the urine. As clearance levels decrease, blood levels of creatinine and.
Creatinine and creatinine clearance tests measure creatinine levels (the level of the waste product) in your blood and urine to give information about how well your kidneys are working. The substance creatine is formed when food is changed into energy through a process called metabolism. Creatine is broken down into another substance called creatinine, which is taken out of your blood by the kidneys and then passed out of your body in urine. Creatinine is made at a steady rate and is not affected by diet or by normal physical activities. If your kidneys are damaged and cannot work normally, the amount of creatinine in your urine goes down while its level in your blood goes up. The creatinine clearance value is found from the amounts of creatinine in the urine and blood and from the amount of urine you pass in 24 hours. This value is the amount of blood cleared of creatinine per minute, based on your body size.
The normal value of 24-hour creatinine clearance in mice is approximately 0.5-1.0 ml/min. This parameter is commonly used to assess renal function in preclinical studies involving mice.
