What I found interesting, that they emphasize so much a paraneoplastic situation as a typical indication for these autoantibody tests. This makes a lot of sense: when the body fights some cancer, it must develop means to destroy cancerous tissue. So here it is not implausible that autoantibodies arise and studies have shown exactly that. Unfortunately for me, I just realized that I have some worrysome results in this regard: my fasting amino acid profiles in blood are almost identical to the gastric (GC) and colorectal cancer (CRC) profiles in
this study, see Fig 2 (the image below. blue colour means deficiency, red excess). I eat fully enough protein. Have no malabsorption or other digestive issues. Have eaten 87.8g protein that day, which is more than fully enough. Had the amino acid profile in the next morning, fasting. There is no normal explanation for deficiencies.

In sum:
- Cancer is a reason for neuronal autoantibodies. (I have high alpha1 adrenergic receptor AB. NMDAr AB is a possibility. A neurologist recently diagnosed autoimmune polyneuropathy in me)
- Amino acid profiles are an ingenious and scientific way for an early diagnosis of cancer, when one can still do sthg and when other means of diagnosis do not yet show much.
I hope for you that in case you take the test, you wont have anything resembling the pictured situations... I discovered all this today, after last week doctors looked baffled at my lacking amino acids that did absolutely not fit my abundant protein intake... Certainly, they did have no clue how that is possible...
Thanks to
@Shawn for pointing me to the Mayo panel!! Without that hint, I would not have found the starting point for all this. Could be that you saved my life... further tests will show...
