How to Use Liquid Starch DIY for Mold Testing: The Pros and Cons

When you notice or suspect mold growth in your home, it's natural to feel concerned and want to take action. One popular option for testing for mold is a DIY kit using liquid starch. While this method can provide some information about the presence of mold spores in the air, it's essential to understand its limitations and potential drawbacks.

The Liquid Starch Method: How It Works

A liquid starch DIY test kit involves placing a small amount of liquid starch on a plate or in a container and then sealing it. The starch absorbs moisture from the air, which can attract mold spores. If mold is present, it will grow on the starch, making it visible.

However, this method only detects certain types of mold spores that are closest to the plate and most likely to settle. Many other spores may go undetected, providing an incomplete picture of the situation.

The Limitations of Liquid Starch DIY Testing

While a liquid starch test kit can indicate the presence of mold spores, it's crucial to recognize its limitations:

* The color of the mold growth on the plate is irrelevant and cannot be used to determine the type or toxicity of the mold.

* The volume of growth does not provide any meaningful information about the sample beyond indicating how fast the particular spore grows in that culture plate.

* The test kit may not detect all types of mold spores, leaving you with an incomplete understanding of the situation.

What Does a Positive Test Result Really Mean?

A positive result on a liquid starch test kit indicates that there are mold spores present in the air. However, it does not necessarily mean that the mold is causing symptoms or that it's a problem in your home.

The biggest issue with DIY testing kits is that they cannot provide the answers to your most important questions: Is the mold I have (or suspect) a problem? Where is it located?

Inconsistent Results and Drawbacks

DIY test kits come with several drawbacks, including:

* No accredited lab certification or chain of custody for legal verification

* Inconsistent lab results from location choice

* Expired collection plates

* Uncontrolled shipping/handling

If you're considering using a DIY mold testing kit, it's essential to weigh the pros and cons carefully. While these kits may provide some information, they are limited in their ability to accurately diagnose and identify mold problems.

In conclusion, while liquid starch DIY testing can indicate the presence of mold spores, it is crucial to understand its limitations and potential drawbacks before using this method. If you're concerned about mold growth in your home, consider consulting with a certified mold inspector or industrial hygienist for a more comprehensive and accurate assessment.
