What Is Asbestos Point Count Analysis?

Asbestos Point Count Analysis is an advanced laboratory method used to quantify the percentage of asbestos fibers in a bulk sample. Unlike standard PLM (Polarized Light Microscopy), which often reports results as “positive” or “negative,” point count analysis provides exact fiber concentrations, typically expressed as a percentage.
 
This type of analysis is required when:
A previous asbestos test result is below or near the 1% regulatory threshold
You need to determine whether a material is legally considered asbestos-containing under CDPHE or EPA regulations
Clearance documentation must be supported by quantitative data

I spoke with Vanessa - they were honest, transparent with me which I really appreciate. I had some questions about lead testing and they were straight shooters with me. Definitely recommend them and will use their business in the future.

Why Does 1% Matter?

In Colorado and across the U.S., building materials are legally classified as asbestos-containing material (ACM) if they contain 1% or more asbestos by weight. If a material tests positive but falls near this cutoff, a Point Count Analysis provides the clarity needed to:

  • Avoid unnecessary abatement
  • Confirm or deny ACM classification
  • Secure permits or clearance for demolition or renovation
  • Reduce liability and delays

When Do You Need Point Count Testing?

After a PLM result shows “trace asbestos” or “<1%”

When regulatory agencies request further confirmation

Before removal or disturbance of suspect materials near the legal threshold

For clearance testing on abated or cleaned materials

To contest or confirm findings from another lab

Typical materials that often require point count analysis:

  • Floor tile mastic (black glue)
  • Sheet vinyl or vinyl backings
  • Drywall joint compound
  • Stucco or wall plasters
  • Roofing sealants, caulking, or tar

How Point Count Analysis Works

  1. Sample Collection
  2. Our certified inspectors collect suspect material samples under CDPHE and EPA protocols. These may come from flooring, ceilings, insulation, or other potential ACMs.
  3. Lab Analysis
  4. Samples are submitted to an NVLAP-accredited laboratory for point count testing using PLM with 400-point or 1,000-point counting methods, per EPA 600/R-93/116.
  5. Results Reporting
  6. Your results are delivered in a detailed report showing:
  • Exact asbestos percentage
  • Type of asbestos fibers (Chrysotile, Amosite, etc.)
  • Interpretation against CDPHE/EPA thresholds
  • Recommendations for next steps

Typical turnaround is 5–7 business days, with expedited testing available.


Is Point Count Required by Law?

Point count analysis is not always required, but is often requested or accepted by CDPHE when:

  • You wish to verify “<1%” results
  • You need to avoid costly abatement for non-ACM material
  • You are seeking official clearance for demolition or disposal

In Colorado, CDPHE Regulation 8, Part B recognizes point count analysis as a valid quantitative method when performed by an approved lab. This makes it a valuable tool for compliance and dispute resolution.

Point Count vs. PLM: What’s the Difference?

Test TypeDetectionResult FormatUse Case
PLM (Basic)Down to ~1%Positive / Negative / TraceGeneral screening
Point Count (Quantitative PLM)Below 1%Exact % of asbestosRegulatory compliance & dispute resolution

If your PLM result says “trace” or “<1%,” a Point Count may save your project thousands in unnecessary abatement.

Frequently Asked Questions

What does “trace asbestos” mean?

It means the lab detected fibers but couldn’t determine the percentage with standard PLM. A point count test is needed for clarity.

Can I use point count to prove material is non-ACM?

Yes — if the result is <1%, it may be exempt from certain abatement requirements under CDPHE and EPA rules.

Is point count analysis recognized by the state of Colorado?

Yes. CDPHE Regulation 8 allows point count data from accredited labs to determine ACM status in borderline cases.

How much does it cost?

Point count testing is more expensive than standard PLM due to the time-intensive process. However, it’s often less costly than full abatement.
