It was not a lab and the results came back at under 5% or .05 in each room.  

I am used to analyzing micro organisms in the lab at the far rear of a building.

I like labs (the breed) and spend a lot of time in the lab ... and I can't resist a pun ... which is why I picked the "bird dog" avatar.kat

One had a 50 lb lab, the other a 60 lb German Shepherd.

If you make it hard you not only irritate them, you increase the likelihood of damage.Does this mean you should make it easy for them to operate a meth lab?

Was there a meth lab?

That same day, after eating a snagged apple from a friend's lunch tray and a sample piece of bread from the bakery next to my university, I headed over to the computer lab and put an ad on Craigslist to become a house-sitter/pet sitter.

Now stopping to help the disabled guy in a wreck a couple miles from my house and finding out that the other car abandoned when we called the cops had a meth lab stashed in the trunk means you can't only be worried about war zone neighborhoods.

It is a Lab but no matter the breed, my insurance does not discriminate (neither do I). 

friend of mine is doing this in portlandia.. look at the big developments I think in the netherlands or other parts of Europe they are away ahead of usAlthough my buddy is more of a philanthropist with this particular endeavor he even donated a fully functional one to the collage... although he hopes to some day turn that around and make them viable financing for himself as well.. but i bet he has spent 250k or more on this so far.. all for science / construction lab at the collage
