Mold Testing: Modern Strategies (Part 3)

Part 3: Choosing the Right Mold Sampling Method – A Decision Tree

When it comes to choosing the right mold sampling method, it’s crucial to consider various factors, including the purpose of the assessment, budget, and the specific concerns of the environment. To help you make an informed decision, here’s a decision tree for selecting the appropriate mold sampling method:

1. Determine the Purpose:

  • Are you conducting routine mold inspections or responding to a specific concern?

2. If Routine Inspection:

  • Consider direct sampling (swab, tape, or bulk) for cost-effective, surface-level assessments.
  • Air sampling is optional but may provide a broader perspective.

3. If Responding to a Specific Concern:

  • Air sampling can help assess airborne mold spore levels and potential health risks.
  • ERMI testing is a good option if you suspect water damage or are looking for a more comprehensive assessment.
  • HERTSMI-2 testing is advisable if you have specific concerns about mycotoxins and health risks.

4. Evaluate Budget:

  • Consider your budget when selecting the method. Direct and basic air sampling methods are generally more budget-friendly, while ERMI and HERTSMI-2 testing can be more expensive.

5. Seek Professional Guidance:

  • If in doubt, consult with a mold professional who can assess your specific situation and recommend the most suitable sampling method.

In this three-part series, we’ve explored the evolution of mold sampling methods, from traditional techniques to advanced approaches. Each method comes with its unique set of benefits and deficiencies, making it essential to choose the right one based on your specific circumstances.
