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 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
High bun creatinine ratio?
"High BUN-to-creatinine ratios occur with sudden (acute) kidney failure, which may be caused by conditions such as shock or severe dehydration. An obstruction in the urinary tract (such as from a kidney stone) can cause an elevated BUN-to-creatinine ratio. A very high BUN-to-creatinine ratio may be caused by bleeding in the digestive tract or respiratory tract."
How is the calculation of creatinine clearance from 24 hour urine collections done?
There is a special device called a toilet hat that you place in the toilet. It fits under the rim. You pee in it, take it out and empty it into a special collection jug set aside specifically for this purpose. After collection of the 24 hour excreted urine,creatinine clearance (CrCl) is calculated using the formula CrCl= (Ucr x V)/ (SrCr x t) where Ucr is creatinine concentration in urine V is volume of urine in ml SrCr is creatinine concentration in the serum and t is the time period of urine collection

Is elevated levels of urine creatinine are found in leukemia?
no
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 does raised creatinine clearance mean?
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 normal urine creatinine level for 5 year old boy My grandson has urine creatinine level of 118 along with increased calcium level. Renal ultra sound is negative for stones.?
Normal creatinine values in urine is 1-2grams per day, no specificity for children vs. adults an increase can be a sign of infection. Normal creatinine clearance values in urine are 100-140ml/min. An increase can be a sign of Kidney disease. As for the calcium levels being elevated it depends on how elevated and whether elevation was in the blood or the urine. Was it total calcium or ionized? Sorry I couldn't help you more.
What condition does a high creatinine level indicate?
An elevated creatinine level indicates renal insufficiency or renal failure.
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.
