I just got home the new marker of the SFC marketed by Kenny De Meirleir, and I did with a friend who is NOT diagnosed with CFS. My friend, however, has had intestinal problems, fatigue and bad health lately, but not months in bed or anything like that, and has no medical diagnosis of CFS, but yes a depression.

I know as I have the SFC since 2005 and I'm on the left in the picture, and my friend is on the right. The first photo is at zero minutes, right when put the urine into the container and the second photo is after 3 minutes as indicated by the instructions of the test. As expected, I gave a strong positive and my urine is darkened, showing an excess of H2S. On my friend, only very slightly and we have no clue whether it is relevant.
