Mold Sampling: Chain of Custody Form

[Guest guest]

I'm sending a mold sample to University of Texas Center for Indoor Air

Research. They said I need to fill out, sign and send along a " Chain

of Custody Form " that is on their site, along with sample to be

tested. Does anyone know why a chain of custody form would need to be

signed. Are they afraid I may want it back, or what? Just kidding of

course. Anyway, does this mean if stachy were found, etc., they could

report it to some agency or something. I just wondering. I know for

Home Depot tests, I filled out name, address and where collected but

they didn't have any chain of custody form. I just find it curious.

Anyone know about this?
