Question 1

creatinine clearance? what for?

Accepted Answer

Kidney function: Creatinine clearance is a calculation that serves as a measure of kidney function. There are 5 stages of kidney disease before end-stage. The stage guides treatment and allows the doctor to monitor changes over time.

Question 2

how to boost your creatinine clearance?

Accepted Answer

Renal health: Creatinine clearance depends primarily on the glomerular filtration function of the kidney. There is no way to boost it above the normal level, nor is there any need for it. If your creatinine clearance is lower than normal, you ought to consult a nephrologist.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. 
Practice safe sex.

Question 3

creatinine clearance --what exactly is it?

Accepted Answer

Calculation: It's a calculation of the kidney function.

Question 4

is it ok to have creatinine clearance of 42 at 92 ?

Accepted Answer

Almost normal: It is normal to lose some filtering units with age so that after age 40 the creatinine clearance starts to fall.
This will be accelerated by hypertension or obesity or diabetes but even in normal individuals it falls at a lower rate.
At age 90 a creatinine clearance of about 60 mls per min would be expected so 42 is close to it.

Question 5

doing creatinine clearance test is pain in the a#@?

Accepted Answer

Peeing in a bottle:): Creatinine clearance is an exact measurement of renal function, much more accurate than calculation made from serum creatinine alone.  The 'pain' i guess you are referring to is that to do the test accurately requires collecting every drop of urine in a special bottle given by the lab for 24 hours.  Enjoy the challenge-:).

Question 6

what are the sources of error for creatinine clearance?

Accepted Answer

Creatinine clearance: The most common cause is improper urine collection which means all the urine is not collected in the container. The other reason could be not collecting blood specimen for serum creatinine once you finished the urine collection. Another reason could be not collecting urine in proper container and the last reason can be not writing the correct total volume of the urine.

Question 7

what does it mean when you have a low creatinine clearance?

Accepted Answer

Impairment: of kidney function. The kidneys are not filtering waste out of the blood as efficiently as they should. Most of the time low creatinine clearance is due to some sort of disease of the kidneys themselves like inflammation or decreased blood supply. Recurrent urinary tract infections can also damage the kidneys. Best to see a nephrologist for evaluation. Thanks for trusting HealthTap!

Question 8

what is the formula for determing a creatinine clearance rate?

Accepted Answer

24 hour urine: 24 hour urine is collected to measure the amount of creatinine excreted in 24x60 minutes. This is then divided by the serum concentration of creatinine to estimate the volume of plasma cleared of creatinine in one minute.

Creatinine clearance rate has mostly been replaced by estimated glomerular filtration rate, that requires only the measurement of serum creatinine.

Question 9

what is the definition or description of: creatinine clearance?

Accepted Answer

Kidney Function: Creatinine clearance is used in clinical practice to give an estimate of overall kidney function, or glomerular filtration rate. Generally normal is considered 100 or above, but it goes down every year and elderly patients may have low clearance which is not abnormal.

Question 10

my creatinine clearance test came back low. what does this mean?

Accepted Answer

Creatinine clearance: Low creatinine clearance means your kidney is not filtering normal amount of creatinine in the urine because of some disease process.
