Measurements of serum thyroxine binding globulin (TBG) by a ligand partitioning sandwich assay were performed in 173 healthy subjects between three months and 92 yr of age. Significant sex-related differences were observed in subjects aged 21 to 50 yr. In males, serum TBG declined progressively reaching a nadir in the fourth decade and then increased with advancing age. In contrast, no significant age-related variation was observed in females.
