1 The catecholamine blood test measures the amount of the hormones dopamine, norepinephrine, and epinephrine in your body.  Doctors usually order the test to check for adrenal tumors in adults and neuroblastomas in children.
Dopamine does not cross the bloodâbrain barrier, so its synthesis and functions in peripheral areas are to a large degree independent of its synthesis and functions in the brain. A substantial amount of dopamine circulates in the bloodstream, but its functions there are not entirely clear.ost types of reward increase the level of dopamine in the brain, and a variety of addictive drugs increase dopamine neuronal activity. Other brain dopamine systems are involved in motor control and in controlling the release of various hormones.
