Molds thrive in warm, damp, and humid conditions, and exposure to mold-rich environments may result in a variety of health effects ranging from mild to severe depending on an individual’s sensitivity or underlying allergy to mold.

Given their ubiquitous presence, testing should be considered in anyone with signs and/or symptoms of mold exposure – or an environmental history for a known current or past exposure to mold.

Individuals at highest risk for health problems when exposed to mold include those with:

• Underlying immune system dysfunction (history of atopy, immune suppression, or immunodeficiency)
• Underlying chronic lung disease
• Infants, young children, and the elderly
• Workers employed in jobs that result in high and ongoing levels of exposure (farm/dairy workers, lumber/wood workers, winemakers).
