There is well a test, the firts one is small capsules against the skin
, then they check reaction after 2 days, than 4 days, and one on the skin
with a drop of reactant, then they pick and see the reaction. After 2 months, it has decreased already due to the removal of bad food (pork, potatoes, tomatoes, cheese, all thinks that can get old and ferment). According to doctor he expect me to go back to normal life after 12 to 24 months.
