They passed no test. FDA doesn't support the CTLM. This touted FDA export certification is meaningless. It means the CTLM isn't harmful.
Put it this way, I could take a lounge chair, build a wooden A frame above where your head would lay, and dangle a flashlight from the A-frame. I could call this a jmurfk brain scanner, and I could get FDA export certification for it, lol.
