What This Value Measures
Creatinine is a breakdown product from muscle metabolism that is excreted by the kidneys. This value serves as a measure of kidney function.
Elevated Value
An elevated value may indicate impaired kidney function, but is also influenced by muscle mass.
Low Value
A decreased value is usually harmless and may occur with low muscle mass.
Note: The value depends on muscle mass, age, and sex.
Reference ranges are typical guide values for adults and vary depending on the laboratory, measurement method, age and sex — always compare with the range stated on your own report. A value outside the range does not automatically mean an illness, and a value within the range does not rule one out. The trend and overall picture are usually more informative than a single value. The doctor's assessment is always decisive.
