Cross Section of a wall
Testing construction materials for asbestos is a crucial step in ensuring safety during renovations. At LCS Laboratory Inc., we frequently receive questions about asbestos testing in materials like drywall and plaster. Below, we address a common inquiry about submitting layered samples for analysis, ensuring you understand the process and options available.
FAQ: How Should I Submit a Multi-Layered Sample for Asbestos Testing?
Question:
I’m planning some home renovations that involve removing existing drywall or plaster. I’d like to test these materials for asbestos. I noticed your form asks for the “Number of layers to analyze,” but my sample contains three layers, and I’m not entirely sure what they all are (possibly sheetrock, plaster, etc.). How should I fill out the form if I’m uncertain about the layers? Also, is a ziplock bag an acceptable way to submit the sample?
Answer:
Thank you for reaching out with this excellent question. Based on your sample description and image, there are three distinct layers (excluding paper) in the material. Here’s how you can proceed:
Testing Individual Layers:
If you’d like to know the asbestos content in each layer separately, we will split the sample into its individual layers and analyze them independently. Each layer will be reported with its own set of results. For this type of analysis, you’ll need to list all layers you want tested in the “Layers” column of the submission form (e.g., Sheetrock, Plaster, Unknown Layer). The cost will reflect the analysis of three individual layers, as they will be treated as separate samples.
Testing the Entire Sample as a Whole:
If you’re only interested in whether asbestos is present in the entire piece of drywall/plaster, leave the “Layers” column blank on the form. In this case, we will test the sample as a single unit, and the cost will be for one sample analysis.
Sample Submission:
Yes, a ziplock bag is an acceptable way to submit your sample. Please ensure the sample is securely sealed and clearly labelled to avoid contamination during transport.

I have the same walls in my house. Are you saying if I pay for one sample and send a wall sample with 3 layers you will test it all as one sample then I will know my walls are either positive or negative for asbestos but if positive I won’t know which layer has asbestos?

Yes this is correct. Let say we find 5% of Chrysotile in your wall. Now you know that there is asbestos there, but you do not know is it in drywall or plaster.
