This test aims to identify moulds that are growing on specific objects / materials. By collecting swab samples, the service will be able to find out the types of moulds to genus level. After the service, you will receive a test report and our recommendations (related services and products) based on the results.

Common Types of Moulds in Homes

  • Aspergillus: a common fungus that can be found in soil and on damp hay, grain and fruit. It is a known aero-allergen, and it is the most common cause of respiratory disease in man.
  • Cladosporium: a common fungus usually associates with plants, wood products, and leather goods. The spores are easily made airborne and as such are a common cause of respiratory problems and allergic reactions.
  • Penicllium: a known and documented aero-allergen. It is commonly found in soil, and it grows readily on fruits, breads, cheeses, and other foods. An opportunistic pathogen, it produces mycotoxins that are toxic to humans.
  • Phoma: a fungus that grows readily on most paper products, such as magazines and books. It grows on some paints and green plants. Phoma is widespread in nature and frequently produces a skin rash or other reactions in mould-sensitive individuals.

Mould & Allergy

Moulds reproduce by tiny spores that can be present on both surfaces and in the air, they live in moist places like bathrooms, kitchens or air conditioners. Moulds remains allergenic and toxigenic to our health even when dead.

As tiny mould spores become airborne, they can trigger or aggravate asthma symptoms and cause allergic reactions, such as nasal congestion, runny nose, sneezing and irritated eyes in people who have mould allergies. Identifying the particular mould species found at home is crucial for you to locate and eliminate the source of mould growth.

Where should I test?

Samples will be taken from up to 5 items / surfaces, suggested testing locations include…

  • Ceilings & walls
  • Cabinets & wardrobes
  • Countertop basins & wash-bowls
  • Air-conditioners (cooling fins / air ducts)
  • Dehumidifiers

Testing equipment

We adopt Mould Swabs™ to perform mould identification. Moist swabs will be used to take samples from any surfaces. The samples will then be sent to Canada Laboratory which has been accredited to ISO 17025 international standard by the Canadian Association for Laboratory Accreditation (CALA) for identification.
