There is someone I have been corresponding with after posting about my brother in law on Facebook. She told me to dismiss out of hand anything people on this forum said. She said there wouldn't be many online groups who understand mould toxicity. She said to me that she suffered from mould illness for years and no-one believed her. She contacted a private clinic in the States, and it cost her eighteen hundred pounds. She said there is now a clinic that tests for micotoxins in the urine in London so it's a lot cheaper. It's called a micotoxin panel test. Turns out she was right all along. I'm just telling you all this, because I have two conflicting parties saying two different things to me. Thanks. ( She said they gave her binders like charcoal or chorella to take, in order to remove the toxic mould. And it worked.)
