Salivary free cortisol is often cited as a noninvasive practical alternative. However, when cortisol concentrations exceed the corticosteroid-binding globulin (CBG) point of 500 nmol\/L, a lack of agreement between salivary and venous blood cortisol has been found. Alternatively, capillary blood may present a minimally invasive, cost-effective, and practical surrogate for determining cortisol concentration.<\/jats:p><jats:sec sec-type=\"purpose\"><jats:title>Purpose:<\/jats:title><jats:p>The aim of this study was to determine whether cortisol concentrations sampled from capillary blood and saliva accurately reflect those found in venous blood across a large range of concentrations after intense exercise.<\/jats:p><\/jats:sec><jats:sec sec-type=\"methods\"><jats:title>Methods:<\/jats:title><jats:p>Eleven healthy aerobically trained male subjects were recruited.
