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.

What is the creatinine clearance test?
Creatinine clearance test. This test evaluates how efficiently the kidneys clear a substance called creatinine from the blood.
Difference between clearance and creatinine clearance?

What should the creatinine level be for dialysis?
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.
What is creatinine clearance?
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.1Creatinine 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).2The result of this test is an important gauge used in assessing excretory function of the kidneys.11. http://en.wikipedia.org/wiki/Creatinine_clearance2. http://en.wikipedia.org/wiki/Creatinine
What do low clearance values for creatinine indicate?
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.
What is the significance of creatinine clearance?
to find out kidney filteration rate.
What is the normal creatinine clearance level during pregnancy?
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.
What characteristics does an abnormal kidney function test have?
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.
What is the normal value of creatinine clearance?
Normal creatinine clearance is 110 to 150 ml / min. exact value is only measured on collecting 24 hour urine, but 2hour urine sample in critically ill patients almost simulate to the 24 hour value
What refers to how plasma is cleared by the kidneys of a particular substance?
Clearance rate. There are formulas for rates such as creatinine clearance. Also, you may be thinking of GFR, or glomerular filtration rate.
What refers to how much plasma is cleared by the kidneys of a particular substance?

What are blood Creatinine levels and how high is 148?
Serum creatinine is taken to measure your creatinine clearance, which is a measure of how well your kidney is functioning. This can be calculated using a couple of formulas most simply the Cockcroft and Gault formula which will take into account your age, weight, height and sex.
