Abstract
- Objectives: To examine the effect of sampling site on levels of free thyroxine (fT4) and thyrotropin (TSH).<br />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.<br />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.<br />Conclusions: Sampling site does not influence levels of fT4 and TSH.<br /> (2010 The Canadian Society of Clinical Chemists.
