TBG (Thyroxine Binding Globulin)
Fasting Required: No

Specimen: Blood

Results: 7 - 10 Business Days

Description:The measurement of TBG can be used to establish the presence of TBG deficiency or excess suggested by abnormal Total serum T4 and T3 concentrations in the presence of normal free levels of these hormones. Definitive documentation of a TBG derangement may avoid unnecessary diagnostic procedures and therapy in individuals with harmless congenital TBG anomalies, and in their relatives.

Methodology: Chemiluminescence
