Surface Cleanliness Test

Evaluates and verifies the cleanliness of any surface (e.g. walls & ceilings, kitchen cabinets, air conditioners and dehumidifiers) by finding out how active the microorganisms activities are on the tested area.

IAQ and PM2.5 Test

Determines the level of a list of common IAQ parameters in indoors. For example, PM2.5, carbon dioxide (CO2), carbon monoxide (CO), nitrogen dioxide (NO2), formaldehyde (HCHO) and volatile organic compounds (TVOC) etc.

Formaldehyde & VOCs Test

Determines the level of HCHO (formaldehyde) and TVOC (Total Volatile Organic Compound) in indoor air and furnishings

House Dust Mite Test

Determines the level of contamination of house dust mites on home textiles (e.g. mattresses, sofas & carpets etc.)

Mould Identification (Surface) Test

Identifies the types of moulds by taming samples of indoor surfaces where mould growth is suspected.

Mould Identification (Air) Test

To find out whether there are airborne moulds spores in the air and identify the mould to genus level by collecting air samples at indoor environment where mould growth is suspected.

Bacteria Identification Test

Identifies the types of bacteria by taming samples on indoor surfaces where the growth of particular microorganism(s) is suspected.

Allergy Blood Test

IgE Test is the ONLY Acceptable Diagnostic Test for Allergic patients, according to the latest guidelines of The Hong Kong Institute of Allergy concerning “in-vitro” allergy tests.

Our service is ideal for people who suffer from asthma or allergies

There is no better defense against environmental allergens than a tailor-made service plan from Johnson Group. We provide the fastest services to locate allergens like dust mites, moulds, bacteria, fungi, particulate matter, formaldehyde (HCHO) & Volatile Organic Compounds (VOC) etc. which have been medically proven to trigger a whole host of allergic reactions like asthma, bronchitis, eczema, sneeze, itchy skin and other health issues.

While it is true that you will not find a surface without bacteria on it, the majority of bacteria that you’ll find are common, non-dangerous species. Studies have shown that of the bacteria found in indoor are: Micrococcus, Staphylococcus, Bacillus, and Pseudomonas.

Mould contamination is one of the major factors in the indoor air quality. Damp environments support the growth of moulds. Many buildings have water leaky or poor ventilation problems and thus favours the mould growth. Children and allergy sufferers are at high risk of health problems from mould exposure.

Allergy is a hypersensitivity disorder of the immune system. Most common environmental allergies occur to airborne allergens, such as dust mite, pollen, pet dander, mould spore, particulate matter or formaldehyde (VOC). Some individuals may respond to allergens which activate the production of IgE, leading to type I hypersensitivity. This will result in sniffling, sneezing, coughing, or itching or even an extreme inflammatory response.
Some main signs of allergy are itchiness, sneezing, inflamed or infected eczema, watering/reddening eyes, runny nose and clogging in the lungs. Allergens are tiny and light perfect for taking wing in the ducts and open air of spaces around your house. Indoor allergens like formaldehyde, dust mite, mould, particles or even volatile chemicals from conventional cleaners can accumulate in your air conditioners, curtains, mattresses, sofas and carpets . Allergens produced by house dust mites are among the most common triggers of asthma. Therefore, deep clean your home regularly is essential.
Immunoglobulin E, or IgE, is a kind of antibody that plays an important role in the development of allergic asthma. Increased levels of IgE may result when you are exposed to allergens, such as dust mite, pollen, pet dander, mould spore, particulate matter or formaldehyde. Your body releases IgE, which then binds with several types of cells like basophils, lymphocytes & mast cells. This can then stimulate your immune system, cause your airways to become narrow and inflamed, and make your asthma symptoms worse.
