Often test kits may not be the answer
for you - it can be more efficient to send pieces of contaminated building
materials directly to our laboratory for isolation and identification.
Such samples are referred to as "bulk samples" in the analytical world.
To send a bulk sample for analysis,
please do the following:
Place the sample in a clean, unused ziplock
bag. Do not mix samples from different locations or of different materials
in the same bag, because you could cross-contaminate material, resulting
in an incorrect analysis.
Place bag with the sample in another ziplock
bag - this double-bagging insures sample integrity during shipping.
Identify information about the sample,
where it came from, some history such as exposed to flooding or other phenomena;
and the date it was collected.
Enclose payment of $100/sample to cover
preparation costs. You will be billed for species identification
later. A sample is considered to be a single type of building material
in its own bag. Example: 3 double-bags each containing separately
labelled wallboard is considered three samples. A large outer
bag containing 4 smaller bags each with a different kind of building material
would be billed as 4 samples.
At the Laboratory, we will aseptically
unbag the specimen and perform several kinds of tests. We will perform
a visual inspection and prepare slides for transmission light microscopy
to look for identifiable molds. We will also culture surfaces on 4 different
kinds of diagnostic growth media to ensure that we can capture living specimens
of molds. After growth of molds on the media, about 1-2 weeks for full
maturity, we will identify the molds.
Ship the sample immediately to our laboratory.
Once we have identified molds on your
bulk sample, we will send you a full report on what we have found. The
report is part of the cost, and includes The report includes information
about known health effects on humans and other organisms, photomicrographs,
worldwide distribution, known growth habitats, as well as detailed physiological,
metabolic and growth parameters.
BULK SAMPLE PRICING
SAMPLE PREPARATION: $100/sample. A
sample is defined as a single kind of building material, such as wallboard,
wood or insulation. If you send us a sample of wood and a sample of wallboard,
the sample preparation fees would be $200. We ask that you send the
preparation fee with the sample.
IDENTIFICATION: We charge $100/species
in aggregate. If you send us 5 samples and we find the same fungus on all
five samples, we charge only $100 for the identification, regardless if
the fungus is found on different kinds of building materials.
