Reference Notes and Guidelines Click here for more details. Reference Notes and Guidelines Note: Revised reference intervals effective 6 Sep, 2025. Reference notes: 1. The drug "phenylbutazone" may cause falsely depressed progesterone results. 2. Falsely increased results may be seen in patients on high doses of biotin (i.e. > 5mg/day). Samples should only be collected from these patients at least 8 hours following the last biotin administration so as to avoid potential interference.
