An abnormal creatinine clearance rate may mean you have a problem with your kidneys. Or it may mean a problem somewhere else in your body is affecting blood flow to the kidneys.
What is CrCl in blood?
The creatinine clearance test is an older test used to check your kidney function. This test allows your healthcare provider to look at samples of your urine and blood to see how much of the waste product — creatinine — is filtered out by your kidneys.
Can drinking water lower creatinine?
Drinking more water could lower the serum creatinine level, but does not change kidney function. Forcing excessive water intake is not a good idea.

The causes of a low serum creatinine concentration are generally well known and include reduced muscle bulk, liver disease, significant fluid overload and poor nutritional status but also augmented renal clearance as seen in pregnancy.
What causes high creatinine level?
Creatinine levels often rise during intense exercise, as more creatine is burned for energy, or because someone may eat a high-protein diet. High levels could also indicate a problem with the kidneys, as these organs get rid of waste products from the body to keep the blood clean.
What level of creatinine requires dialysis?
By comparing the blood and urine level of this substance, the doctor has an accurate idea of how well the kidneys are working. This result is called the creatinine clearance. Usually, when the creatinine clearance falls to 10-12 cc/minute, the patient needs dialysis.

During the creatinine clearance test you will need to collect your urine for 24 hours and then your blood will be drawn.
How long does it take for a urine test to clear creatinine?
Done in two parts, the creatinine clearance test involves collecting your urine over a 24-hour period of time and then having your blood drawn. These samples are then tested to see how much creatinine was filtered through your kidneys over the 24-hour window.
What organs filter out creatinine?
Normally, creatinine is filtered out of your blood by your kidneys . If you think of each organ in your body as having a job, the kidneys are the filters. They’re responsible for cleaning your blood. The material that’s removed from your blood leaves your body in your urine.

Can you eat meat before a creatinine clearance test?
In general, you can eat normally before and during the creatinine clearance test. However, you may be asked not to eat overnight. Your provider may also ask you not to eat meat before the test. This could change the results because there’s higher levels of creatine in meat, which would cause your body to have higher levels of creatinine during the test.

You may also have an ultrasound, computed tomography (CT) scan, or other imaging test done of your kidneys.
Why is it important to check creatine levels?
It is essential to determine CrCl and serum creatine levels when there is suspicion of renal dysfunction. A common complication that results in increased serum creatine levels is acute kidney injury (AKI)[21]A sudden decrease in GFR and oliguria are signs of AKI. This type of injury is common in 20% of hospitalized patients and leads to volume overload, electrolyte imbalances and drug toxicity[21]Management for patients with AKI is to perverse kidney function and prevent further complications.
What does elevated creatinine mean in renal function?
Elevated serum creatinine levels and a decreased CrCl rate are usually indications for abnormal renal function. For these patients, it is recommended to perform a thorough history, physical exam, renal ultrasound, and urinalysis.[14] Relevant patient history includes medications, history of edema, gross hematuria, diabetes, and polyuria.[13] Physical examination for signs of vasculitis, lupus erythematous, endocarditis, and hypertension can help narrow the diagnosis — renal ultrasound assesses the kidney size, echogenicity, and possible hydronephrosis. Enlarged kidneys usually indicate diabetic nephropathy, focal segmental glomerulosclerosis, or multiple myeloma. A urinalysis positive for proteinuria or urinary sediment indicates the presence of glomerular disease. [13]
What is the normal creatinine level for a male?
The normal range of CrCl is 110 to 150mL/min in males and 100 to 130mL/min in females.[15] Serum creatinine level for men with normal kidney function is approximately 0.6 to 1.2mg/dL and between 0.5 to 1.1 mg/dL for women.[15] Creatine levels above the normal range correlate with a reduction of GFR and indicate renal dysfunction.
What is the best way to measure renal function?
Alternatively, the biochemical marker creatinine found in serum and urine is commonly used in the estimation of GFR.[3] Creatinine clearance (CrCl) is the volume of blood plasma cleared of creatinine per unit time. It is a rapid and cost-effective method for the measurement of renal function. Both CrCl and GFR can be measured using the comparative values of creatinine in blood and urine.
How does CKD affect the kidney?
CKD occurs through multiple pathologic mechanisms of injury and affects several compartments of the kidney.[22] The loss of microvasculature and increased fibrosis leads to hypoxia within the kidney, making patients more substile to acute kidney injuries with poor healing.
How many ml of blood is a sample?
A blood sample of 1 mL ( minimum 0.5 mL) in a labeled tube, preferably stored in refrigerated or frozen temperature.
What is creatinine in skeletal muscle?
Creatinine is a breakdown product of dietary meat and creatine phosphate found in skeletal muscle. Its production in the body is dependent on muscle mass.[6] The CrCl rate approximates the calculation of GFR since the glomerulus freely filters creatinine. However, it is also secreted by the peritubular capillaries, causing CrCl to overestimate the GFR by approximately 10% to 20%.[4] Despite the marginal error, it is an accepted method for measuring GFR due to the ease of measurement of CrCl.
What is creatinine clearance test?
The creatinine clearance test helps provide information about how well the kidneys are working. The test compares the creatinine level in urine with the creatinine level in blood.
What is creatine in urine?
Creatinine is a chemical waste product of creatine. Creatine is a chemical the body makes to supply energy, mainly to muscles. By comparing the creatinine level in urine with the creatinine level in blood, the creatinine clearance test estimates the glomerular filtration rate (GFR).
How is creatinine clearance measured?
Creatinine clearance is usually determined from a measurement of creatinine in a 24-hour urine sample and from a serum sample taken during the same time period.

How to determine creatinine clearance?
Creatinine clearance is usually determined from a measurement of creatinine in a 24-hour urine sample and from a serum sample taken during the same time period. However, shorter time periods for urine samples may be used. Accurate timing and collection of the urine sample is important.
Why do you need a creatinine test?
Your doctor or other health care provider may order a creatinine test for the following reasons: To make a diagnosis if you have signs or symptoms of kidney disease. To screen for kidney disease if you have diabetes, high blood pressure or other conditions that increase the risk of kidney disease. To monitor kidney disease treatment or progression.
What is creatinine in urine?
Creatinine is a chemical compound left over from energy-producing processes in your muscles. Healthy kidneys filter creatinine out of the blood. Creatinine exits your body as a waste product in urine.
What does it mean when your creatinine levels are high?
The amount of creatinine in your blood should be relatively stable. An increased level of creatinine may be a sign of poor kidney function.
Overview

Why are blood creatinine levels checked?
Creatinine has been found to be a fairly reliable indicator of kidney function. Elevated creatinine level signifies impaired kidney function or kidney disease.
What are normal blood creatinine levels?
Normal levels of creatinine in the blood are approximately 0.6 to 1.2 milligrams (mg) per deciliter (dL) in adult males and 0.5 to 1.1 milligrams per deciliter in adult females. (In the metric system, a milligram is a unit of weight equal to one-thousandth of a gram, and a deciliter is a unit of volume equal to one-tenth of a liter.)
What are considered high creatinine levels?

What are the symptoms associated with high creatinine levels?
The symptoms of kidney dysfunction (renal insufficiency) vary widely. They generally do not correlate with the level of creatinine in the blood.
Why do people not know CKD?
People may have CKD but not know it because they do not feel sick. A person's glomerular filtration rate (GFR) is a measure of how well the kidneys are filtering wastes from the blood. GFR is estimated from a routine measurement of creatinine in the blood. The result is called the estimated GFR (eGFR).
What is the BUN level?
Blood urea nitrogen (BUN) level is another indicator of kidney function. Urea is also a metabolic byproduct which can build up if kidney function is impaired. The BUN-to-creatinine ratio generally provides more precise information about kidney function and its possible underlying cause compared with creatinine level alone. BUN also increases with dehydration.
Can Bactrim cause elevated creatinine?
Certain drugs (for example, cimetidine [ Bactrim ]) can sometimes cause abnormally elevated creatinine levels. Serum creatinine can also transiently increase after ingestion of a large amount of dietary meat; thus, nutrition can sometimes play a role in creatinine measurement.
What is creatinine in blood?
Creatinine is a waste product in your blood that comes from normal muscle wear and tear. The kidneys are responsible for removal of creatinine from the blood, so if your kidney function declines, creatinine levels in the blood rise. Creatinine levels are checked to assess kidney function. They are usually checked with another kidney function marker ...
