This is my first post on this forum.

4 yrs. ago I would have told you that Prolab was NOT the lab to use. They were not qualified to analyze anything IMHO.

Today I use them and recommend them. They have the finest laboratory in the United States, their turn around time is fast, prices very reasonable. I like their reports much better than other laboratories and can get them online the next day.

I sometimes buy them off the shelf at Walmart or Home Depot but they are expensive there and you have to pay extra for analysis. I only do this if I accidentally run out of them on the truck. It is best to buy them direct at www.reliablelab.com

The organization I work for gives out the retail kits to homeowners who can't afford them, but they still have to pay extra for analysis.

Their retail kits are everywhere but Prolab's niche is home inspectors. I'm not one normally but I know this much.

Hope it helped.
