1. The Organ Measurements (OM) domain contains details of organ measurements and relative organ weights.
  2. Terminal body weight will be recorded in the BW domain.
  3. Organ measurement ratios within a single test or measurement should either be pure ratios with the unit shown as "RATIO" or percentages with the unit shown as "%."
  4. Currently in this model, the applicant is not expected to attempt to relate the organ weight ratios to their underlying source results used in the calculation through the RELREC or GRPID mechanisms.
