Abstrakt: Objectives: To examine the effect of sampling site on levels of free thyroxine (fT4) and thyrotropin (TSH).
Design and Methods: fT4 and TSH were determined by a current immuno-assay in paired samples of capillary and venous blood drawn from 30 euthyroid adults.
Results: Mean levels of fT4 and TSH did not differ significantly between capillary and venous blood; capillary and venous levels correlated well and did not differ significantly from unity.
Conclusions: Sampling site does not influence levels of fT4 and TSH.
