Home Allergy & Allergen Testing Services
Indoor allergy and allergen concerns can come from many different sources. RC Duct Cleaning provides laboratory-based environmental testing to help homeowners, businesses, and property managers better understand the particles present inside their property.
01.
Home Allergy Testing
Professional Home Allergy Testing helps evaluate airborne and environmental particles inside houses, apartments, condos, and townhouses. Samples are collected and sent to a laboratory to identify and count materials such as pollen, mold spores, pet-related particles, dust, mites, skin cells, hair, insects, fiberglass, and other particles included in the analysis.
02.
Commercial Allergen Testing
Commercial Allergen Testing helps businesses, offices, apartment buildings, and managed properties better understand airborne and environmental particles found inside the building. Laboratory particle analysis provides documented information about the materials identified in the collected samples.
What Can Allergy & Allergen Testing Identify?
Depending on the sample and laboratory analysis requested, testing can identify and count a variety of airborne and environmental particles found inside residential and commercial properties.
✓ Pollen
✓ Mold Spores
✓ Pet Hair & Dander-Related Material
✓ Household Dust & Particles
✓ Mites & Mite-Related Material
✓ Human Skin Cells
✓ Human Hair
✓ Insect Material
✓ Fiberglass Particles
✓ Soot or Ash, When Applicable
✓ Other Particles Identified During Laboratory Analysis
These are also consistent with the types of biological and particulate contaminants EPA discusses in indoor environments; EPA specifically notes pollen, mold spores, pet dander, dust-mite material, pest-related material and human skin cells in indoor dust and air. Instead of guessing what may be circulating inside your property, laboratory particle analysis provides documented information about what was actually found in the collected sample.
Signs You May Want Home Allergy or Allergen Testing
Indoor environmental concerns are not always visible. Testing may be useful when you want a better understanding of the particles present inside your home, office, apartment, or commercial property.
✓ Allergy-like concerns seem more noticeable while indoors
✓ You have pets and are concerned about pet-related particles
✓ Dust returns quickly after cleaning
✓ Seasonal pollen may be entering the property
✓ There has been previous water damage or a mold concern
✓ You recently completed construction or renovation work
✓ You are concerned about fiberglass or airborne fibers
✓ Occupants have concerns about the indoor environment
✓ You recently moved into a home, apartment, or office
✓ You want documented laboratory information about indoor particles

What Affects Allergy & Allergen Testing Pricing?
Testing prices vary depending on the type of laboratory analysis requested, number of samples required, number of areas being evaluated, and the size and type of property. Residential homes and larger commercial properties may require different testing approaches.
Pricing Factors
✓ Number of samples needed. Evaluating several rooms or areas may require additional samples.
✓ Type of laboratory analysis. Different environmental concerns may require different types of particle analysis.
✓ Number of areas being evaluated. Testing one room may require a different approach than evaluating multiple areas.
✓ Residential or commercial property. Larger buildings and managed properties may require additional sampling or planning.
✓ Specialized particle analysis. Additional analysis for specific materials may affect the final price.
✓ Property size and layout. Larger or multi-level properties may require additional evaluation.
Understanding Your Laboratory Results
Your laboratory report provides information about the particles identified in the collected samples and the quantity or relative abundance reported by the laboratory. Depending on the analysis requested, findings may include pollen, mold spores, pet hair or dander-related material, dust, mites, human hair and skin cells, insect material, fiberglass, and other particles.
Important Note:
The laboratory report tells you what was identified in the indoor environmental sample. It does not determine which substances you personally are allergic to or diagnose a medical allergy.
What Happens After You Receive Your Results?
The appropriate next step depends on what the laboratory identifies and the conditions inside the property. Understanding the particles present can help homeowners, businesses, and property managers make more informed decisions about the indoor environment.
Possible Next Steps May Include:
✓ Addressing mold or moisture concerns
✓ Improving filtration or HVAC maintenance
✓ Professional air duct cleaning when appropriate
✓ Addressing excessive pet-related particle accumulation
