Re: does this sound correct?

I don't think you'll get the answers you need from the secretary - ask if you

can see a sample report to know how it comes. $800 sounds too cheap for what we

all need... The only thing that possibly could do what we tend to need (in my

ignorant estimation) is the Omni 3000 and not too many places have one.

yes, and even at this price its too expensive if its not accurate. ---

Is the Omni 3000 available for non professionals to use?

What labs do bulk sampling for mycos now? Was that Texas Tech or is

it P & K? thanks

What types of folks are trained to use the Omni 3000? Who to call?

I've been researching mycotoxin testing and found Mycotoxin Testing

Lab (http://www.mycotoxintestinglab.com/). Swab and bulk samples.

Doesn't appear they do air testing.

Look at the list of mycotoxins they test for. Some of these look like

ones you get growing on grains...is that right? (aflatoxin) Not on

building materials. ??

I asked two local 'experts' from the IAQ list whether they had heard

of this company and they hadn't.

One said air samples of mVOCs are very often false negative, so they

aren't helpful.

Mycotoxin Testing Lab also sells Contents Decon, which supposedly

neutralizes mold byproducts. Anyone heard of this??
