Performance of low-dose cosyntropin stimulation test handled via plastic tube

Purpose Studies on 1 μg low-dose test showed that among 1 μg cosyntropin samples pushed through long IV plastic tubing, some adrenocorticotropic hormone dosage was not recovered, and in healthy volunteers it provided subnormal cortisol responses. The aim of the current study is to assess whether there is any loss in adrenocorticotropic hormone 1–24 concentration when pushed through a short plastic tube, and to assess serum and salivary cortisol...
