You know I'm talking about the test for iodine deficiency where you put some liquid iodine on skin and see what happens... if the stain stays there for long your body doesnt need iodine and vice versa. Anyone done this test? I put some iodine on my skin 8 hours ago and now its almost totally vanished so it seems I'm deficient (according to the hair test my iodine is low too). Any experiences with this test?
