Creatinine is a waste product produced by skeletal muscle tissue. Creatinine is usually measured in the plasma as a biomarker of renal function.
Creatinine may occasionally be measured in body fluid to assess for the presence of urine in the fluid.
Viscous samples are unsuitable for analysis
Ambient (8 - 24 degrees Celsius)
The creatinine concentration in urine is usually an order of magnitude greater than elsewhere in the body (millimolar vs micromolar quantities). Therefore creatinine concentration may be measured in an unspecified body fluid to see if the fluid contains urine, which may indicate that the source of the fluid is in communication with the urinary tract.
Please note that the creatinine assay has not been validated for measurement on body fluid specimens. Results must be interpreted with caution.
