Do reference ranges have to be on the same page (printed or electronic) as the laboratory result?  

No. While it is preferred to have the reference range documented on the same page and adjacent to the laboratory result, the requirement is flexible enough to accommodate different information management systems when it is impractical to do so. For both waived and non-waived testing, two criteria must be met when reference ranges are not supplied on the same page along with the laboratory result: The reference range must be located elsewhere within the permanent medical/clinical record. The result must have a notation directing the reader to the location of the reference range(s) in the medical/clinical record.
