@DMF, you could check via a urine 5-HIAA test. Ray told me in an email exchange in February of 2015 that "Whole blood serotonin isn't very informative, because it isn't harmful when it's bound in the platelets, and harmful when it's free in the plasma; urine 5-HIAA (a serotonin metabolite) is an easy test."
