Good Laboratory and Microscope Procedures are critical in making sense of environmental test field samples just as good and thorough field investigations produce more useful results than a quick "air test for mold" or "culture test for mold" performed with no building inspection and no client history collection.

Competent, trained, experienced aerobiologists, mycologists, and microbiologists can identify mold or other particle sample contents with good accuracy.

Depending on the experience of the laboratory, it is also possible to interpret the meaning of the sample for the building and its occupants.

Laboratory professionals who have also performed the field inspection can make useful extrapolations from lab results. Hasty work by disinterested parties may be less than accurate or useful for building occupants and owners.

What to do about mold in buildings

HIRE AN EXPERT - Do you need to hire a mold expert, bring in a mold remediator, hire a handyman, or clean up for yourself?

See WHEN TO HIRE A MOLD EXPERT for details about how to decide when hiring a mold expert is justified and appropriate.

See MOLD INSPECTORS & MOLD TESTERS for a list of mold investigators whose work is familiar to us. Other mold investigators and test consultants may also be competent and qualified.

MOLD CLEANUP GUIDE- HOW TO GET RID OF MOLD gives basic advice for a do-it-yourself mold cleanup project.

Detailed guidance about what to do about mold is provided at ACTION GUIDE - WHAT TO DO ABOUT INDOOR MOLD.
