Creatinine and creatinine clearance tests measure the level of the waste product creatinine (say "kree-AT-uh-neen") in your blood and urine. These tests tell how well your kidneys are working. Another substance, creatine (say "KREE-uh-teen"), is formed when food is changed into energy through a process called metabolism .

Creatine, the precursor for creatinine is synthesized in the liver. About 2% of creatine is converted into creatinine daily. In a normal, healthy individual, creatinine is excreted from the kidneys. Extra-renal excretion of creatinine occurs only when there is severe impairment of renal function. In the 112 hypertensive subjects, carotid compliance was positively correlated to creatinine clearance even after an adjustment for age, gender, and blood pressure. At less than 55 years of age, creatinine clearance represented 20% of the variance of carotid compliance.

Related terms: Serum (Blood) The typical human reference ranges for serum creatinine are 0.5 mg/dL to 1.0 mg/dL (about 45 μmol/L to 90 μmol/L) for women and 0.7 mg/dL to 1.2 mg/dL (60 μmol/L to 110 μmol/L) for men. The significance of a single creatinine value must be interpreted in light of the patient's muscle mass. 2017-09-07 Furthermore, creatinine is actively secreted in small amounts in the body resulting in GFR determined through creatinine clearance typically being overestimated by 10-20%. Despite its limitations, creatinine clearance still provides an acceptable estimation of GFR due to its ease of measurement when compared to inulin clearance. 4 Below are three formulas often used for estimating GFR through serum creatinine.

Clearance betyder noget i retning af "rensning" og fortæller om, hvor gode nyrerne er til at udfiltrere et bestemt stof fra blodet. Når clearance aftager, aftager nyrefunktionen. Når man derfor har mistanke om at nyrerne ikke virker ordentligt, opsamler man urin i et helt døgn. I urinen måler man, hvor meget kreatinin der er udskilt.

A low creatinine clearance might indicate a serious kidney disorder. The kidney damage can either be acute (sudden) or chronic (long-term), which can be identified by repeated tests over time. A lower than normal value may indicate : Life-threatening infection. Shock.

Creatinine clearance is one way to estimate your glomerular filtration rate (GFR), or how well the kidneys are filtering your blood. The GFR is the main number used by your provider to determine how well your kidneys are working. The creatinine clearance test is not used very often any more. Enter data in table and creatinine Clearance will be calculated according to the Cockcroft and Gault Formula (Nephron 1976;16:31-41). Suitable for adults only.

The GFR is the main number used by your provider to determine how well your kidneys are working. The creatinine clearance test is not used very often any more. Creatinine clearance A higher than normal creatinine clearance level can be indicative of anemia or increased blood flow to the heart.
