There is no way to directly test for brain serotonin or dopamine in humans without killing then and dissecting their brains. You can test for metabolite but that doesn't show you actual neurotransmitter levels.
I would look at prolactin then. Very good surrogate to intra cellular dopamine/serotonin levels
