Creatinine is measured as an indicator of kidney function. It is a waste product produced by muscles and filtered out by the kidneys. Elevated levels of creatinine in the blood can be a sign of impaired kidney function.
1 answer
Creatinine is another name for chemical waste. It is a breakdown product of creatine phosphate in muscle.
1 answer
Creatinine is a waste product in blood that is filtered by the kidneys. High levels of creatinine may indicate decreased kidney function, as the kidneys are unable to filter and excrete it properly. Monitoring creatinine levels can help assess kidney function and identify potential kidney problems.

A creatinine level of 88 is within the normal range for adults, which typically falls between 0.6 to 1.2 mg/dL. However, it's important to consider other factors such as age, gender, muscle mass, and underlying health conditions when interpreting creatinine levels. If you have concerns about your creatinine level, it's best to consult with a healthcare provider for further evaluation.

The creatinine clearance test compares the level of creatinine in urine with the creatinine level in the blood. (Creatinine is a breakdown product of creatine, which is an important part of muscle.) The test helps provide information on kidney function.

How the test is performedThis test requires both a blood and urine sample. You will collect your urine for 24 hours, and then have blood taken.
- For information on giving a blood sample, see: venipuncture.
- For information on how to collect the urine sample, see: 24-hour urine collection.
The samples are sent to a laboratory. The laboratory specialist measures the level of creatinine in both the urine and blood samples, and looks at how much urine you collected in 24 hours.
The clearance rate is then calculated. The calculation is adjusted for your specific body size.
The creatinine clearance appears to decrease with age (each decade corresponds to a decrease of about 6.5 ml/min./1.73 m2).
How to prepare for the testIf the collection is being taken from an infant, a couple of extra collection bags may be necessary.
How the test will feelThe urine test involves only normal urination and there is no discomfort. When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.
Why the test is performedThe creatinine clearance test is used to estimate the glomerular filtration rate (GFR).
However, because a small amount of creatinine is released by the filtering tubes in the kidneys, creatinine clearance is not exactly thto the same as the GFR. In fact, creatinine clearance usually overestimates the GFR. This is particularly true in patients with advanced kidney failure.
Normal ValuesClearance is often measured as milliliters/minute (ml/min). Normal values are:
- Male: 97 to 137 ml/min.
- Female: 88 to 128 ml/min.
Note: Normal values ranges may vary slightly among different laboratories.
What abnormal results meanAbnormal results (lower-than-normal creatinine clearance) may indicate:
- Acute tubular necrosis
- Bladder outlet obstruction
- Congestive heart failure
- Dehydration
- Glomerulonephritis
- Renal ischemia (blood deficiency
- Renal outflow obstruction (usually must affect both kidneys to reduce the creatinine clearance)
- Shock
- Acute renal failure
- Chronic renal failure
- End-stage renal disease
The risks of the test are minimal and are related to the blood draw process. Rarely, the following will occur:
- Excessive bleeding at blood draw site
- Fainting or feeling light-headed
- Hematoma (blood accumulating under the skin)
- Infection (a slight risk any time the skin is broken)
- Multiple punctures to locate veins
Factors that may interfere with the accuracy of the test are as follows:
- Incomplete urine collection
- Pregnancy
- Vigorous exercise
Drugs that can interfere with creatinine clearance measurements include: cimetidine, trimethoprim, and drugs that can damage the kidneys, such as cephalosporins.
The creatinine clearance test should only be done for patients who are medically stable. Such patients may have a rapidly changing creatinine clearance, and therefore any result may be inaccurate.

Creatinine is a breakdown product of creatine, which is an important part of muscle. Creatinine is removed from the body entirely by the kidneys. This article discusses the test done to measure the amount of creatinine in your urine.
A blood test can also be used to determine your creatinine level. See: Serum creatinine
Alternative NamesUrine creatinine test
How the test is performedA random urine sample or a 24-hour collection may used. For information on how to collect a 24-hour urine sample, see: 24-hour urine collection.
How to prepare for the testYour health care provider may tell you to temporarily stop taking certain medicines that may interfere with test results. Such medicines include:
- Cephalosporins (cefoxitin)
- Cimetidine
- Cisplatin
- Gentamicin
- Trimethoprim
The test involves only normal urination, and there is no discomfort.
Why the test is performedThis test can be used as a screening test to evaluate kidney function. It may also be used as part of the creatinine clearance test. It is often used to provide information on other chemicals in the urine such as albumin or protein.
Normal ValuesUrine creatine (24-hour sample) values can range from 500 to 2000 mg/day. Results are highly dependent on your age and amount of lean body mass.
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What abnormal results meanAbnormal results of urine creatinine are nonspecific, but may be due to any of the following conditions:
- Glomerulonephritis
- High meat diet
- Kidney failure
- Muscular dystrophy (late stage)
- Myasthenia gravis
- Prerenal azotemia
- Pyelonephritis
- Reduced kidney blood flow (as in shock or congestive heart failure)
- Rhabdomyolysis
- Urinary tract obstruction

Creatinine can also be measured with a urine test. See: Creatinine - urine
Alternative NamesSerum creatinine
How the test is performedBlood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.
Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.
Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.
How to prepare for the testThe health care provider may tell you to stop taking certain drugs that may affect the test. Such drugs include:
- Aminoglycosides (for example, gentamicin)
- Cimetidine
- Heavy metal chemotherapy drugs (for example, Cisplatin)
- Kidney damaging drugs such as cephalosporins (for example, cefoxitin)
- Trimethoprim
When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.
Why the test is performedThe test is done to evaluate kidney function. Creatinine is removed from the body entirely by the kidneys. If kidney function is abnormal, creatinine levels will increase in the blood (because less creatinine is released through your urine).
Creatinine levels also vary according to a person's size and muscle mass.
Normal ValuesA normal value is 0.8 to 1.4 mg/dL.
Females usually have a lower creatinine than males, because they usually have less muscle mass.
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What abnormal results meanHigher-than-normal levels may indicate:
- Acute tubular necrosis
- Dehydration
- Diabetic nephropathy
- Eclampsia (a condition of pregnancy that includes seizures)
- Glomerulonephritis
- Kidney failure
- Muscular dystrophy
- Preeclampsia(pregnancy-induced hypertension)
- Pyelonephritis
- Reduced kidney blood flow (shock, congestive heart failure)
- Rhabdomyolysis

No, creatinine kinase and creatinine are not the same. Creatinine kinase is an enzyme found in muscle cells, while creatinine is a waste product produced by muscle metabolism. Measuring creatinine levels in the blood is a common way to assess kidney function, while creatinine kinase levels are often monitored in conditions affecting muscles, such as heart attacks or muscular dystrophy.

To calculate the 24-hour urine creatinine, the amount of creatinine excreted in the urine over a 24-hour period is determined by collecting all urine passed during this time. The creatinine concentration in this pooled urine sample is then measured. Finally, the creatinine concentration is multiplied by the volume of the urine collected to obtain the total amount of creatinine excreted in a 24-hour period.

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.

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
