Blood Plasma Analysis
The blood plasma test that discovered my histidine and histamine problem was done by Monroe Medical Research Laboratory* at the request of the nutritionist who is a chiropractor and has the medical authority. The actual blood was drawn at a walk in blood lab who obtained the special test tubes required for the test as per Monroe's instructions. The test required a 24 hour fast (not eating) and avoiding all chemicals including: soap, toothpaste, and deodorant. It profiled my neurotransmitter and various amino-acids levels. The specific test was called a "Depression Platelet Profile". I never found out why it was called that. Some significant chemicals profiled, and their function are listed in the table below. Based on the symptoms I described previously, you can probably guess if my levels of each were high or low.

* Monroe Labs has closed. The same test can be done by: Vitamin Diagnostics ELN Laboratories in New Jersey.
Chemical Profile
Function
Epinephrine (Adrenaline) Part of the mechanism that provides energy to muscles, helps regulate heart and breathing rate. Excess levels cause nervous energy and panic attacks. Low levels cause lack of energy, exhaustion and memory problems.
Normetanephrine (Adrenaline) Part of the mechanism that provides energy to muscles, helps regulate heart and breathing rate. Excess levels cause nervous energy and panic attacks. Low levels cause lack of energy, exhaustion and memory problems.
Histamine Neurotransmitter involved in biological processes like allergy and injury to increase blood flow to the cells. Counteracted by adrenaline. High levels cause Meniere's like symptoms, focus problems.
Dopamine The brains natural antidepressant. Low levels cause bad moods and depression.
Norpinephrine Aids the brains ability to make logical decisions and solve logical problems.
Glutamine Helps you determine where your body parts are in time and space. Low levels lead to clumsiness and poor balance.
Arginine Instrumental in building muscle tissue. Low levels can lead to muscle tears, reduced strength, slowed muscle healing and growth.
Serine Calmative agent. Reduces adrenaline spikes. High levels allow histamine to rise. Low levels allows adrenaline spikes and possible panic attacks.
Phosphoethanolamine Genetic material that aids in the creation of ATP or energy. Low levels cause low energy levels.
Methionine Helps produce insulin which controls blood sugar. Helps in the production of muscle and connective tissue. Helps to reduce histamine levels.
Cystine Instrumental in hair, skin and connective tissue growth.
Histidine Becomes histamine. High levels increase histamine.
