... The ratio of these two catecholamines differs considerably among species: in humans, cats and chickens, roughly 80, 60 and 30% of the catecholamine output is epinephrine. Following release into blood, these hormones bind adrenergic receptors on target cells, where they induce essentially the same ef ...

Appendix — Tests of Endocrine Function and Normal Values
... A combined provocation test is used to test for adequate excretion of GH, TSH, LH and FSH. Basal levels of GH are of no value because of the pulsatile nature of secretion. Likewise, exercise and sleep are both very poor stimuli for GH secretion and should not be used. IGF-1 and IGFBP-3 levels, if in ...
