Creatinine clearance test measures the level of creatinine (a waste product) in the urine and blood. This test tells how your kidneys are functioning.
Blood Creatinine Levels
The blood creatinine helps one understand how the kidneys are functioning. Elevated levels suggest that the kidneys aren’t functioning correctly. Serum creatinine level predominantly depends on the muscle tissue; thus, by and large, men have higher levels of creatinine compared to women.
Creatinine Clearance Test
This test assesses how well the kidneys eliminate creatinine from the blood. A Creatinine Clearance Test is more effective than a Serum Creatinine Test.The test is carried out on a urine sample collect through the interval of 24 hours, as well as on a blood sample.
Blood Urea Nitrogen-To-Creatinine Ratio
- The levels of blood urea nitrogen and blood creatinine are used to ascertain the BUN to creatinine ratio.
- This ratio helps the physician evaluate problems, like dehydration, that cause irregular / anomalous creatinine and BUN levels.
- BUN test calculates the quantity of urea present in the blood. It tells the physician how well the kidneys are functioning.
Creatinine Clearance Normal Range
Normal creatinine clearance levels for males and females are
- Men: Between 97 and 137 ml per min / 1.73 m2 (0.93 to 1.32 ml per sec / m2 IU)
- Women: From 88 to 128 ml per min / 1.73 m2 (0.85 to 1.23 ml per sec / m2 IU)
Creatinine clearance tests are carried out for the following purposes
- To check if the kidneys are functioning optimally.
- To check for changes in the kidney disease
- To assess severe dehydration
