Fast, Dependable Results when it Matters the Most
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

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
- Sample Collection
- Our certified inspectors collect suspect material samples under CDPHE and EPA protocols. These may come from flooring, ceilings, insulation, or other potential ACMs.
- Lab Analysis
- 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.
- Results Reporting
- 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 Type | Detection | Result Format | Use Case |
| PLM (Basic) | Down to ~1% | Positive / Negative / Trace | General screening |
| Point Count (Quantitative PLM) | Below 1% | Exact % of asbestos | Regulatory 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
It means the lab detected fibers but couldn’t determine the percentage with standard PLM. A point count test is needed for clarity.
Yes — if the result is <1%, it may be exempt from certain abatement requirements under CDPHE and EPA rules.
Yes. CDPHE Regulation 8 allows point count data from accredited labs to determine ACM status in borderline cases.
Point count testing is more expensive than standard PLM due to the time-intensive process. However, it’s often less costly than full abatement.
