Air Quality Mold Testing & Lab Reports

Mold Testing determines indoor air quality in occupant buildings, also before and after Mold Remediation.

Dryfast provides:

Air Quality Testing using “Zefon Air-O-Cell” cassette

This test provides complete report of the indoor air quality, What type of Mold Spores and How many spores in the air you breathe, This Is the most accurate way to test if you have indoor air quality concerns, It tells in detailed report with graphics ether the indoor air is good or with elevated Mold Spore count.

Inspection Data Collection and Analysis:


Microbiological Mold Test – Air samples as well as surface samples with cultured swabs, non-viable biotape lifts and bulk materials will be used as deemed appropriate based on our professional experience. Samples are analyzed by an environmental microbiologist at an AIHA (American Industrial Hygiene Association) accredited environmental laboratory. We will run nonviable air tests called spore traps as they provide a broad spectrum of mold spores. Indoor air samples are analyzed in comparison to an Outdoor Sample. Besides collecting intact mold spores, spore trap testing can also be used to identify hyphal fragments, pollen grains, textile fibers, human skin flakes, and plant hairs that may be airborne. We also offer an expanded particle analysis as an option that provides a more comprehensive breakdown of dust components such as gypsum, insect parts, silica, dander, cellulose synthetics fibers, talc, dust mites, pollen, fiberglass, combustion by-products (soot from furnace, candle or kerosene heater, wood ash).When necessary, we are equipped to draw wall cavity samples when there is reason to suspect mold growth within walls/ceilings.

The Value of Mold Testing


What is the value of mold testing? Too often I have heard that if you see the mold just get rid of it!

This is true to a certain extent however, what if you can smell the mold but can’t see it? There is a strong musty mold odor or some form of dampness. I agree if you see the mold get rid of it and/or have the mold treated, but what about mold that may be hidden or undetected? Mold spores are not visible to the naked eye that are airborne. Just because walls, ceilings, or floors are not moist does not indicate that mold spores are not present. Every building have some forms of mold, we are looking for unusual or excessive mold growth.

The value of mold sampling is Threefold:

The air testing will determine the mold spore elevations present in the room if they are excessive beyond our natural environment.

The air sampling or direct identification will determine the type of mold species such as mycotoxic, pathogenic,or allergenic.

The sampling will determine if the mold is growing actively or is dormant. (Dormant mold is known to be allergenic and can still compromise a building or a persons health)

Our field experience with hundreds of mold inspections and assessments in the past several years there are times when the mold in the building looks worse than what may appear and at other times the room walls and ceiling look clean and innocent only to find that the room has excessive mold in mycotoxic, allergenic in nature. Although there are currently no federal standards or guidelines regarding results of fungal samples and there are no levels which are typical or permissible there is still value, especially in finding and correcting the source of the mold such as a water or moisture problem.

Dryfast provides qualified and certified professionals to provide sampling and protocol in your mold assessment and mold inspection.

Air Quality Mold Test is available :



Same day – if the mold test was done before 11 am.

Next Day – if mold test was done before 1pm.

3 days – This is The standard, all others contact for rush service price.

The Air-O-Cell® is a unique air sampling cassette specifically designed for the rapid collection of a wide range of airborne aerosols including mold spores, pollen, insect parts, skin cell fragments, fibers (e.g. asbestos, fiberglass, cellulose, clothing fibers, etc.) and inorganic particulate e.g. ceramic, fly ash, copy toner, etc.). The Air-O-Cell® collects both viable and non-viable sample specimens, providing a much broader overview of potential allergens contaminants than conventional sampling techniques.

Swab Test

Swabs are an easy way to test suspected areas for contamination such as sewage damage, biohazards like blood, vomit, urine on carpets, concrete or soil or for post mold remediation.

Available : same day, next day or standard 3 days,

Extremely accurate way to test any surface for contamination.

Bad Lab Results are the following:


The two most critical components in mold spore count test results are :

Higher mold spore counts per species of mold inside the home then outside the home.
Different mold spore species present inside the home that are not present outside the home.

Stages of Mold Testing:


1. Air Sampling

When Dryfast is called to investigate an area for Mold, a sample of indoor and outdoor air is often required. This procedure is called Air Sampling. Air Sampling tells what the level of airborn fungi is in the indoor and outdoor environment.

A building with no mold contamination should have about the same amount of fungi present in the air as the surrounding outdoor environment.

moldout testing and inspection
The Air-O-Cell operates upon the principle of inertial impaction. Particulate laden air is accelerated as it is drawn through the cassettes tapered inlet slit and directed towards a small slide containing the collection media, where the particles become impacted, and the air flow continues out the exit orifice. The adhesive nature of the collection media prevents the collected particulate from blurring or being washed off during the laboratory staining process, and eliminates sample loss from vibration during handling and shipment.

2. Tape Swab Test

Using a cotton material swab to wipe the surface to be tested. After touching one to three surfaces in the same location ,the swab is sealed in a container and sent to microbiology laboratory for examination. Swab testing is generally used to detect mold and determine what type of mold are present . This test is not typically designed to identify mold spore count.

3. Tape slide test

Tape slide tests are similar to swab test. a piece of tape placed onto area to be tested, lifted, and placed onto glass microslide.

The tape slide is then sealed and and sent to the microbiology laboratory for examination.
