Term Description

This term is intended to collate similar measurements for the LOINC SNOMED CT Collaboration in an ontological view. Additionally, it can be used to communicate a laboratory order, either alone or in combination with specimen or other information in the order. It may NOT be used to report back the measured patient value. https://lo.inc/ce2mb6

Part Descriptions

LP29119-2   Thyroxine.free
Free T4 is the metabolically active fraction of thyroxine and is the precursor of triiodothyronine (T3). Free T4 is a sensitive test for thyroid function and is increased with hyperthyroidism and decreased with hypothyroidism. Free T4 is not affected by changes in thryoxine-binding proteins.
