Episode 12: The Power of qPCR Mold Testing – Mold Sampling Series Part 3

When it comes to mold testing and sampling, no test is the end-all, be-all. Each case we face is unique, and the testing and sampling should reflect that.

As your mold consultants, our goal is to always give you the most accurate information to protect your home and health. While basic sampling provides us with vital data, sometimes we just need to dig deeper.

qPCR sampling is a type of testing that results in an overall contamination rating for a space. It uses a unique type of sample collection to evaluate a space at a deep level looking for contamination from a specific set of molds. It can also provide insight into the history of a property to indicate if contamination may have been building up over several years. 

In this episode of a Secret Life of Mold, our host Craig Cooper is once again joined by Mold Inspection Sciences Texas COO, Mike Marshall, and Mold Inspection Sciences COO, Brandon Apple to discuss this “next level” type of testing, which includes:

  • What qPCR testing is and how it works
  • Details about the ERMI scale and its reliability
  • The HERTSMI Scoring System
  • EMMA Testing
  • The importance of industry collaboration

And more!

Although a property may appear without issues, there can often be unseen contaminants that may be impacting your health and wellness. To find the right solution, we need to understand your needs and what’s happening in the environment around you. If you’re ready to dig deep, we’ve got another exciting level of testing to break down for you. Don’t forget to download a copy of our guide for you to take notes or have on hand.

Big Three from Episode #12

  1. qPCR sampling is a type of testing that uses a unique sample collection to evaluate a specific set of molds at the DNA level.
  2. When evaluating a home, it’s essential to look at all contributing factors for comprehensive conclusions, not just the ERMI score system.
  3. qPCR is a vital type of testing not just for environmental contamination but also for treatment programs for those diagnosed with mold illnesses.
