Interpreting neurotransmitter test results:

Here is Dr. Amy on interpreting neurotransmitter test results:

Neurotransmitters function in your brain and body in ways that define your personality and your physical abilities. Low serotonin has been implicated in OCD, perseverative behavior, depression, anxiety, and GI dysfunction. Dopamine is critical for executive function, attention, focus, goal motivated behavior, and mood. Higher norepinephrine relative to epinephrine appears to be a factor in ADD/ADHD.
I use several tests to get a complete sense of neurotransmitter (NT) formation, balance, and breakdown.  The level of starting materials for serotonin and dopamine, ie, tryptophan, phenylalanine, and tyrosine, are found on a UAA. From these levels, I may be able to draw some conclusions about the availability of BH4 in your body, which is needed for the conversion of tryptophan to serotonin, phenylalanine to tyrosine, and tyrosine to dopamine. Dopamine then goes on to become norepinephrine and epinephrine.
Then, I look at the information given on neurotransmitter testing, ie, the level of the NT found in the sample.
Finally, I look at the level of breakdown product(s) from the NT, whether it is serotonin, dopamine, epinephrine, or norepinephrine. The rate of NT breakdown is a major factor in the final level of NT present in your body. Breakdown information is on the MAP test.
So, in order to assess NT status and performance in your body, first look at a UAA to see what the level of the starting material is for the particular NT. From the UAA, you may also be able to draw preliminary conclusions about your BH4 levels. Then, look at a NT test to see the reported NT level. And, finally, look at a MAP test to give you a measurement of NT breakdown product(s). You can draw your conclusions from the integration of these three pieces of data.
This method of evaluating neurotransmitter status gives you a more complete picture of the activity of neurotransmitters in your body, rather than looking at neurotransmitter levels alone.

So excellent!  I literally learn something on every single call and I get clarification on things that have been lingering on my mind…
You are giving people a huge gift by empowering them…It’s about helping the patient become their own healer by taking them to a higher level of consciousness…
Thank you so much Dr. Mullan.  Thank you so, so much for everything you do.
Wow!  I have to tell you, this was such an uplifting call.  It’s so nice to hear good news especially about a child.  Anxiety, OCD and a host of other mental/psychiatric symptoms have been a huge hurdle for me.  So to hear this story of all those awful symptoms totally going away is such a bright light for me!!!!

This is brilliant.  I hope a lot of people not doing methylation work will see this.  I wish I’d seen this before I started doing daily injections of B12 and folic acid and ended up in a crisis. Maybe had I known to have the genetic methylation stuff going, the IV therapies I did that really helped would not have been so traumatic…
