What else is in your sample?

Mold is only part of what can collect on a surface. The Other Allergens Add-On broadens the laboratory review of the same samples so you can explore other identifiable particles and debris, alongside mold findings.

Depending on what is present and identifiable, a broader particle review can describe materials such as pollen, fibers, skin cells, insect fragments, and other debris. Not every particle is an allergen, and the report only describes material identified in the samples submitted.

Why look beyond mold?

Musty smells, past leaks, unusual spots, accumulating dust, or concerns about health issues may prompt a closer look at your surroundings. Mold exposure can cause allergy symptoms and irritation, and can worsen asthma in susceptible people. Some other indoor allergens can also trigger allergy or asthma symptoms. Finding out more about a collected sample can add context to questions about your home.

A surface sample does not measure what you breathe, identify every allergen, or establish a safe or unsafe exposure level. It cannot diagnose a health condition or determine whether your home caused symptoms. Discuss health concerns with a qualified healthcare professional.

One collection, a broader look

  1. Choose your 1-, 2-, or 4-room package.
  2. Select Other Allergens before checkout. It applies to every sample at $48 per sample: $48, $96, or $192 respectively.
  3. Follow the same collection instructions and keep each sample separately labeled. No extra sample is required for the add-on.

FAQ

Your mold testing questions, answered

Which package should I choose?

How do I collect and submit my samples?

Follow the tape-lift collection instructions provided with your order. Label each sample and enter its room, surface, collector, date, and time using your secure order link. Download the Sample Details Sheet and include it with your labeled samples.

When will I receive my results and shipping label?

Your prepaid expedited shipping label is emailed separately. Laboratory results are available within 48 hours of sample receipt. Shipping transit time is separate from laboratory turnaround.

What can a sample report tell me?

The report describes the samples you submit. It does not establish conditions throughout an entire home, diagnose a health condition, or replace an on-site assessment. If you need a report for a specific third-party purpose, confirm its requirements before ordering.

What does a surface mold sample tell me?

Laboratory analysis describes the mold findings in the surface sample you submit. Record the exact room and surface so the findings can be matched to that location. Sampling several rooms adds context across the areas you choose; it does not assess every part of your home.

What if the mold test I’m looking for isn’t listed?

Contact us with details about the test you need or what you want to find out. If you know the test name or collection method, include it, along with the number of locations you would like to sample. We can suggest an appropriate test, its cost, and lead time before you order.
