Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Use the conversion factors below to convert each analyte from mcg/g creatinine to nmol/mol creatinine:

 

Conversion factors

Cortisol: mcg/g creatinine x 413=nmol/mol creatinine

Cortisone: mcg/g creatinine x 415=nmol/mol creatinine

 

Cortisol molecular weight=362.5

Cortisone molecular weight=360.4

Creatinine molecular weight=149.59
