Reference Notes and Guidelines

1. Individulas with clinically overt hypo or hyperthyroidism have corresponding low or high FT4 and/or FT3. Individuals with sub-clinical hypo or hyperthyroidism usually have normal FT4 and/or FT3.

2. Anti-TPO and Anti-Tg follow up tests may be helpful in the assessment of abnormal TSH results.

3. Flagging is based on non-pregnant adult euthyroid and pediatric ranges only. Pregnancy ranges are not flagged, please review individually.
