What is the best way to test neurotransmitters levels: Norepinephrine, Epinephrine, Dopamine, Serotonin, Gaba, Histamine, 5Hiaa, Dopac, Taurine, Glycine, PEA, and Glutamate.If the best way is urine, should they all be tested using the 24 hour urine test or a random urine test. If some are better done with random urine which ones?
Thank you
