Can EDC sample for antigens; dust mites; viruses; and Legionella?
Sampling and interpretation of antigen (cat, dog, mouse, cockroach proteins) and dust mite concentrations is available and sampling is affordable. Environmental sampling for viruses is not recommended. Air sampling for Legionella is not recommended, only water sampling. Legionella is addressed elsewhere. Does bacteria play a role in indoor air quality? Bacteria in the indoor environment are common but certain types and concentrations can be problematic. Bacteria is primarily sampled from suspected source reservoirs (i.e. humidifiers, condensate pans) or air sampling. Isolation of bacteria by laboratory culture remains the primary method of environmental sample analysis (i.e. direct microscopy is not used, in contrast to fungal spore analysis). Endotoxin (from bacterial cell walls) sampling and analysis is a promising science. Bacteria in the environment seldom form discrete visible evidence other than slime, biofilm, or foam, typically found in standing water. Fruity, sour, or putrid o
