Creatinine is a byproduct of the breakdown of creatine, which is found in muscle tissue. It is continuously produced by muscle metabolism and excreted from the body by the kidneys. Creatinine levels are routinely measured in medical tests as an indicator of kidney function.
Creatinine is formed as a byproduct of the breakdown of creatine phosphate, a high-energy molecule that provides the energy required for muscle contraction.
The process takes place in muscle tissue and results in a steady stream of creatinine being released into the bloodstream.
Creatinine is primarily excreted from the body through the kidneys. Creatinine is filtered out of the bloodstream and into the urine as blood flows through the kidneys.
The rate at which the kidneys excrete creatinine is an indicator of how well they work.

Creatinine is filtered out of the bloodstream and into the urine as blood flows through the kidneys. The rate at which the kidneys excrete creatinine is an indicator of how well they work. High levels of creatinine in the blood can indicate kidney dysfunction, whereas low levels can indicate muscle mass loss or other medical conditions. Creatinine levels are routinely measured in medical tests to assess kidney function. A blood sample is drawn and the amount of creatinine in the blood is measured. The results are used to calculate the glomerular filtration rate (GFR), which is a measure of how efficiently the kidneys filter waste from the blood.
