The Visual Contrast Sensitivity (VCS) Test is a great tool in the home health investigator and biohacker’s toolbelt. When I have clients who are experiencing symptoms of biotoxin illness, this is the first test I suggest.
I am usually met with blank stares.
I know it sounds crazy, but your ability to detect contrast is one of the first things impacted when you are exposed to biotoxins (including mold). It’s not a foolproof method, but it does give me a good vantage point in discovering the hidden health threats in my client’s homes.
How Does It Work?
The test works by measuring one of the neurologic functions of vision called contrast. Contrast sensitivity can be affected by exposure to biotoxins (such as mold and bacteria-produced toxins), nutritional deficiencies, VOCs, parasites, and bug and insect stings/bites.
The test involves looking at a series of lined patterns as the contrast is reduced. The challenge is seeing light from dark, and finding the “edges” of the pattern.

Where Can I Take the Test?
The test is FREE, takes about 20 minutes, and can be completed in the comfort of your own (well-lit) home. Take your free test at VCSTest.com.
What if My Results Show Impaired Visual Contrast?
First things first. You need to locate and remove the source of the problem. This will likely involve a mold inspection.
I recommend CAP DNA mold testing in favor of the wildly praised ERMI test. You can find more information about this test, along with my other recommended resources here.
Once your home is free of health hazards, you may want to consider working with a Shoemaker Protocol-certified doctor who can help you treat the symptoms of biotoxin-related illness.
