The SCIO can't measure Fluoride but does have Iodine in the matrix. The only way we can get a glimpse at the amount of loose Halogens in the body is by looking at the reaction of a homeopathic remedy called Halogens in the matrix.
Keep in mind I have been taking Lugol's since Feb 6th mostly +150mg now down to 50mg due to the massive heavy metal detox I am still dealing with (getting better).
Anyhow this item was pretty reactive during the first few weeks of Lugol's and has been pretty much NON reactive since then. But now its back up and starting to climb...
Two choices, we are getting more by having it sprayed on our food/air or my body found some more and is detoxing.
