Is their any test for the levels of serotonin, norepinephrine, dopamine&gabba in the brain because a dr on tv said that the test is now available. True?

No. The levels of those chemicals in the brain can only be measured with a spinal tap. Any blood test does not really measure it because the the brain and the body are in separate systems. Also, even if you did have the levels numbers, we really don't know what to do with them. Certain levels don't necessarily indicate how you're doing. Please save your money. .
