That's called 'trace testing'. You take one swab and run it round all the inside house surfaces. There is no point in setting levels because there is no control on the size of the surface being swabbed. Then if you get a 'trace' you have no idea which room or surface it came from and then you have to do swabs from each surface at 100cm2 to find out if there is really a problem and what the levels are. This is much more expensive.
So doing trace testing (which is what this thread started about) is probably pointless because it is hit and miss and all it will do is cause concern. The problem as I understand it is hazardous residue from Clan labs not meth users?
Wait until 'testers' start looking at used cars!
