A different method for allergen sampling is to collect a dust sample directly from an environment. This is done by using a vacuum with a specialized collection device. The collection device connects to the hose of a vacuum and traps the dust in a filter sleeve. This filter sleeve is what is sent to the laboratory to be analyzed.
When the sample arrives at the laboratory it is first sieved and weighed. It's recommends that all dust sample be sieved and weighed.
The purpose of sieving the sample is to remove large fibers that may have been picked up by the vacuum. Once those large fibers are removed, the dust sample is weighed because the results are typically reported per gram of dust which makes the initial weight of the sample critical. The results can also be reported in per square area, although this is rare.
Standard lab results turnarounds within 15 days. Faster turnarounds available at an increased cost.
A drawback of dust sampling is that allergen deep in a carpet may not be getting airborne regularly. A dust sample doesn’t measure current exposure directly. Dust samples are better for a historical view of the allergens in a home.
Group Allergens Testing w/ no survey or mold inspection $275
We get calls to test for allergens in a property for various reasons. It may be that a client of ours is allergic to cats and is purposely moving into an apartment building that has never allowed the occupants to have cats.
Before signing a lease or buying the apartment, our client wants to ensure that there are no cat allergens in the new space.
A dust sample would be best for this case. Another more common example is when an individual is highly sensitive to a certain allergen and wants to know if that particular allergen is present in her home. An indoor air quality sample would be best for this case.
Poor air quality can be caused by many factors. Our air quality testers can test the air in every room in your house and examine circulation patterns.
Poor air quality can be caused by many factors.
Most people who search for indoor air quality testing are experiencing symptoms when spending time in a building, and those symptoms abate when they leave the property. This is often referred to as “sick building syndrome”.
Identifying the causes of building-related symptoms is quite challenging. There are so many varying types of air quality issues that a comprehensive approach is required. Some people use the term “Air Quality Testing” to describe mold sampling or VOC tests.
Collecting Air Sample
Dust mite particles are often found in pillows, mattresses, carpeting and upholstered furniture. They float into the air when anyone vacuums, walks on a carpet or disturbs bedding and they settle once the disturbance is over.
Dust mites. Dust mites – sometimes called bed mites – are the most common cause of allergy from house dust. Dust mites are a common cause of asthma in children.
Dust mites live and multiply easily in warm, humid places. They prefer temperatures at or above 70 degrees Fahrenheit with humidity of 75 to 80 percent. They die when the humidity falls below 50 percent. They are not usually found in dry climates.
Indoor Air Quality Testing Service
For indoor air quality allergen air sampling, the approach we prefer collects an air sample for 5 days. A device is set up so that it continuously runs for that time period. During that time, air passes through the apparatus and allergens are collected on an electrostatically charged plate. This type of sampling is very simple but it requires a sampling time that is longer than dust sampling.
The indoor air quality sample is sent to a laboratory which analyzes the dust found inside of the device. Once it’s analyzed the results tell us the amount of certain allergens per volume of air. Allergens included in the results are weed pollen, tree pollen, grass pollen, mouse, roach, dust mite, cat, and dog. We prefer to collect a sample in the bedroom, but it can also be helpful to test other areas of the home.
