Hi, here's my two cents.
The Neuroscience company you used for your tests appears to use
Pharmasan Labs, they have CLIA certification which is good, however, I don't know if they're accredited by anyone with clout. Obviously, this is not an 'FDA' approved test, and no one is claiming it is.
What I mean is, that as a doctor siting in his/her office, this is the first thing they will think when they see this test result. Is it 'legit'? The answer is yes, but then there are so many other variables such as:
Is the method of detection in-house, or used by others? Is the method of detection considered reliable? If not, are there superior ways to measure what you want to look at.
I'd say a key question here is, is looking at the levels of various metabolites in creatine a reliable way to measure neurotransmitter levels in the sample (e.g. blood/urine)? If you can get the answer to this, then I would have much more faith in the result. NB: The result isn't 'wrong', you just have to know if it's reflective of true neurotransmitter levels in your
brain. If you can afford it, a possible thing to do is to re-take the test in a few months. (Doctors generally don't like single shot test results for something they are being asked to act upon, especially if the test method is from a private lab and not in general use).
Your Taurine is high. I am struggling to find any research on this or how it related to CFS to be honest probably as it's very hard to assess levels of it in the brain without some wonderfully expensive brain scan or more invasive method.
The paper below may interest you, although I cannot possibly say if your test is 'reliable' or indeed is looking in the correct area to associate with the research below. I am just showing you some possible links to immunity/neurology because..... CFS seems to involve toxicity of some sort to neurons, making them 'excited'. This could be anything I presume from oxidative stress/autoimmunity or even pathogens.

If i had your test result, I'd see what the doctor says, repeated it if necessary and also take a look at my Melatonin levels (probably low in CFS),and also at glutamine/glutamate amino acids with a
24hr urine test.
In CFS I would expect the glutamine/glutamate results to be abnormal. Other CFS patients have found this also. What it means, I cannot say for certain. It's just generally interesting I find, to discover consistent abnormalities.
I hope you get some favorable response from your doctor, but also try and be realistic how they will respond, especially if they are not CFS specialists or experienced in understand the relevance of amino acid readings.
