The Wisconsin State Laboratory of Hygiene (WSLH)/Wisconsin Occupational Health Laboratory (WOHL) offers a wide range of microbiological testing related to indoor air quality for health agencies, government agencies, industrial hygienists and private citizens.

The Bioaerosol Unit analyzes for bacteria and fungi from air, bulk and wipe samples; Legionella from water samples; bacteria, fungi and Mycobacterium in cutting fluids. We also perform endotoxin testing. We provide sampling equipment, media, wipes and cassettes to our customers.

To guarantee quality results, a complete Quality Control and Quality Assurance program is maintained. We participate in the EMPAT proficiency testing for environmental isolates. The Bioaerosols laboratory is fully accredited by the American Industrial Hygiene Association (AIHA).
