Abstract

Animals were accustomed to our venipuncture procedures and often extended a leg from the cage without struggling for sample collection. Blood collection in a transport box resulted in elevated GH and cortisol values. The present data suggest that such responses may complicate interpretation of GH and cortisol measurements derived from samples collected by venipuncture.
