The test is free, and takes about 5 minutes to do online, if you are interested. The test has its own baseline; you don't have to comparison to previous scores; you take the test, and it tells you whether or not you may currently be affected by biotoxins.
I actually am very curious about this and will ask you for more info later since I know I won't get a chance to do the test today or tomorrow. Also, do you understand the mechanism for how a vision test would determine how well someone can detox mold?! Lastly, I wear either glasses or contact lenses (since 12 yrs old) and assume I would wear them for the test (otherwise I am blind and will automatically fail it)!
