DEFINITION
To measure a urine cortisol:creatinine ratio (UCCR), a single midstream free-catch urine sample is used; cortisol and creatinine are both measured and the concentrations converted into the same units; the UCCR is simply the ratio of the two values.
A normal UCCR is less than approximately 10–30 × 10-6 depending on the laboratory; this value has no units and is typically reported without the scientific notation, e.g. 10 × 10-6 would be reported as 10.
