If you paid contractors to decontaminate your house you should request evidence they actually did but more than likely, they made contamination worse.I very much doubt you had the mould spores removed, and I…Read more

Urine tests are the norm but not much use. WE offer them but only if requested by medical practioner helping the client
Blood tests are far better and more useful.

Real Time Labs and Great Plains offer Urine tests at relatively low cost but again be warned of usefulness.

Always ventilate. You can have 99% humidity in the Antarctic and its dry as a bone , whereas 30% humidity in death valley Arizona is like a sauna .

Neuroquant is a measurement of brain volume in different areas.

They always come back with something. The real issues are inflammagens and they can be minute but often associated with mould and bacteria
Be very careful about Mycotoxin testing a negative doesn’t mean anything and if its positive it still means…Read more

I would look for inflammagens and particulates. Fragrances and VOCS are more likely to affect those suffering with MCS.

Few DHs have filters and they are certainly not HEPA.

The simple answer is if your looking for decontamination the answer is NO. But before the solicitors contact me just ask this question. What is decontamination?

It may be sufficient decontamination for some people but not others and your response may be unique to you. One of the best ways of knowing if decontamination will work is to assess whether the proposal is to remove contamination or simply look like its gone away.

The answer is of course because you have excess moisture in the air causing condensation and or your trying to prevent relative humidity going over 70% (, because you mistakenly you may believe that’s a trigger point for mould growth. The reality is 99% humidity in the Antarctic is bone dry while…Read more
