Creatinine blood levels measured as part of a CMP or a BMP may be compared with the level of BUN (blood urea nitrogen) that's measured in the same test.A UACR compares the amounts of creatinine and albumin in your urine to get a more accurate measurement of how much albumin is in your urine. If larger amounts of albumin pass into your urine, it may be a sign of kidney damage. Normally your kidneys filter out just a trace of albumin, or none at all. Albumin is the main protein found in blood. Creatinine levels in urine may be used to calculate a urine albumin to creatinine ratio (UACR), which is sometimes called a microalbumin creatinine ratio.A creatinine clearance may still be useful to help identify the cause of high or low levels of blood creatinine in people who have very high muscle mass or a loss of muscle mass from age, illness, or the loss of an arm and/or leg. Like an eGFR, it estimates how fast your kidneys filter waste. This is called a creatinine clearance calculation. Creatinine levels in blood and urine maybe be compared with each other.An eGFR can also help show how serious kidney disease may be. An eGFR is a more accurate way to measure kidney health than creatinine levels in blood or urine alone. The calculation includes information about your age, weight, height, and sex. This is called an estimated glomerular filtration rate (eGFR). Creatinine levels in blood are often used to calculate how fast your kidneys filter waste out of your blood.So, the results from creatinine testing are often used in calculations or compared with other substances to help get more information: That's because people make different amounts creatinine depending on how much muscle they have, the foods they eat, their age, and how active they are.
