HPA Profile: Provides measurement of 6 primary urinary neurotransmitters: Serotonin, GABA, Glutamate, Dopamine, Norepinephrine, Epinephrine. Salivary Adrenal Hormones are also measured: 4 timed Cortisols and 2 DHEAs.

This profile assesses the six neurotransmitters that affect the hypothalamic-pituitary axis (HP) as well as the adrenal hormones cortisol and DHEA. Since the HPA axis initiates an adrenal response, this profile allows the practitioner to assess that response and make therapeutic decisions based on the information. Neurotransmitters are measured from a single urine sample, while cortisol (X4) and DHEA (X2) are measured from four saliva samples, the first taken between 7:00 and 8:00 am and then one every five hours thereafter for the remaining three samples.
