The following symptom list with the rates of symptoms find in ME/CFS according to studies may be useful to you
http://wwcoco.com/cfids/bernesx.html eg 86% of us have low blood pressure (many of the rest of us have dysregulated BP with it possibly swinging both ways).
So consider.. do you have what is considered low BP?
................
Rombergs Test (I think its around 70% of ME patients (Im talking of the classical ME patient group rather then general CFS) are postive on the Rombergs test. (you could do this one at home if you have someone to catch you).

....
The ME abnormal finding on MRI scans is "elevated numbers of puntuate lesions, particulary in the frontal lobes and subcortical areas" that quote comes from the canadian consensus document "A clinical case definition and guidelines for Medical Practioners
When looking for findings which are often found in ME you arent looking for just abnormal findings but rather "specific" abnormal findings in which have been related to ME. (I have no idea of what the one they found on your scan is or if its related to what I just quoted above).
...........
As another said.. Hypercoagulability may show up in ME eg flow cytrometry, fibrinogen, thrombin/anti thrombin complexes etc. My abnormal hypercoagulability showed up on an APTT test which a hospital did as part of the hospital standard blood work stuff.. (it had never been on any of my standard doctors blood tests).
My hypercoagulability also showed up on a coagulation studies test which my CFS specialist got done.
.....
ME Autonotmic issues which very commonly show up on tests, most/nearly all ME patients have issues here.. eg POTS (postural orthostatic tachycardia syndrome or NMH (sudden hypotension which happens on standing). (may be seen by doing poor mans testing at home with BP/heart monitor or by a proper tilt table test).
............
food or chemical sensitivities developing.. is another fairly strong sign I think that it is probably ME. (I dont think these commonly start appearing in other illnesses). This issues thou may develop later in the illness.
.............
Another finding which is a common ME one I have is a low but still within normal range white cell count (some may go out of normal range low). Very low normal, can be indicative of LONG TERM chronic infection and some ME specialists will on seeing this will treat eg antivirals etc, after seeing this. (mine only just stays in the normal range, its on the border at times).
I think that can be high/high normal in some who havent had ME/CFS long term.
As another said NK cell levels and FUNCTION is often not good in ME.
........
The abnormal EEG finding in ME is "elevated EEG activity in theta and beta frequencies and increased intracerebral electrial sorces in left frontal region delta and beta frequencies in eyes closed condition may be identified. Reduced sources in right hemisphere (beta) may be noted during verbal cognitive processing" quote from the canadian consensus defination document.
(I had that abnormality on testing).
............
It may be noted that the person has also FM on testing the fibro trigger points. That condition commonly coexists.
...............
The canadian consensus document also mentions cortisol "24 hr urine free cortisol". Mine is abnormal on test with that (yet my morning cortisol blood test is fine).

Virology
............................
low body temperature or the opposite low grade fevers are common in ME
....
I myself thou they arent mentioned in the canadian consensus doc say also other common things in ME found are
- abnormal glucose (hypoglycemia).. ive had this show up on blood tests a couple of times and some ME specialists talk quite a bit about that
- low free testosterone (as Ive noticed so many of us at this site have had abnormal findings in that area so have come to think this may be a common ME finding).
- iron studies (low ferritin.. that is to do with iron storage). Interestingly thou my ferritin is low, my normal iron test is normal.. my CFS specialist says he often sees low ferritin in his CFS patients and associates this with CFS.
- Vitamin D (most patients have a deficiency).
- I cant remember what they are called.. but many ME patients loose the moons on their fingernails (that lighter part at the bottom of the nail. There was a ME/CFS specialist who once mentioned this and this is true for me.. only my thumb nails now show their moons. I assume this one would be found more in those who have had ME for quite a while. Maybe that happens in other chronic illnesses too?).
For more test abnormalities commonly found in ME .. check out the canadian consensus document
http://sacfs.asn.au/download/International Consensus Criteria.pdf (sorry i cant tell you what page its on as I have the overview document of it at home). In the overview document.. right at the end before the references, there is a whole page of tests titled "Tests for abnormalities in ME/CFS"
