Visual contrast sensitivity test or a VCS Test

What is a VCS Test?

Visual Contrast Sensitivity (VCS) testing for mold toxicity, also known as the "VCS Test," is a specific type of visual assessment used as a screening tool for individuals who may have been exposed to mold or mycotoxins. Mycotoxins are toxic substances produced by certain molds, and exposure to them can have various health effects, including neurological symptoms.

It is believed that mycotoxins attack mitochondria in the body, the eyes containing the highest levels of mitochondria in the body. A visual contrast test can help determine if further testing is needed based on your eyes' ability to differentiate contrast in images.

The VCS test is based on the work of Dr. Ritchie Shoemaker, who developed a protocol to evaluate patients with suspected mold exposure. The test involves viewing a series of patterns on a computer screen and identifying whether a given pattern is tilted to the left or right. The patterns are designed to test the ability to perceive contrast and spatial orientation.

What Do VCS Test Results Mean?

The underlying principle of the VCS test is that exposure to mold and mycotoxins can cause a dysfunction in the innate immune response, leading to a chronic inflammatory response syndrome (CIRS). This syndrome can affect various body systems, including the visual system, resulting in reduced contrast sensitivity and other visual disturbances.

The VCS test is not a diagnostic tool for mold toxicity or CIRS. Instead, it is used as part of a comprehensive evaluation that includes a thorough medical history, physical examination, and laboratory tests. A positive VCS test result, combined with other clinical findings, may suggest the need for further investigation for HLA variant and begin treatment for CIRS.

The VCS Test Process

The Visual Contrast Sensitivity Test involves a series of tasks designed to evaluate a person's ability to distinguish between varying degrees of contrast. The test typically requires the participant to view a series of images or patterns, each with a specific level of contrast, and identify the differences. The test is conducted in our office on a computer with special software. It involves a detailed questionnaire and a contrast vision test. Your results are then analyzed and discussed with you to help you determine if you need further testing.

Visual contrast sensitivity test symptoms

Do You Need a VCS Test?

If you suspect that you have been exposed to mold or mycotoxins and are experiencing CIRS symptoms such as chronic fatigue, headaches, or cognitive difficulties, it is essential to consult with one of our mold and CIRS specialists in diagnosing and treating mold-related illnesses. We can help determine whether the VCS test or other diagnostic tests are appropriate for your situation and then develop a personalized treatment plan for you to begin healing your mind and body.


What is Visual Contrast Sensitivity (VCS) Testing?

VCS testing is a non-invasive, computer-based test that evaluates your ability to see subtle changes in contrast. It's designed to assess how well your visual system detects differences in light and dark.

How does VCS testing relate to mold exposure?

Exposure to mold and mycotoxins (toxic substances produced by molds) can potentially affect the visual system, leading to reduced contrast sensitivity. VCS testing is used as part of an evaluation for individuals who suspect they may have been exposed to mold and are experiencing symptoms that could be related to mold toxicity.

What symptoms might indicate the need for VCS testing?

Symptoms of mold toxicity can vary widely but may include chronic fatigue, headaches, memory and concentration problems, and respiratory issues. If you have these symptoms and suspect mold exposure, VCS testing might be recommended.

How is the VCS test conducted?

The test is performed in our office on a computer with a special program that analyses your responses. You'll be asked to answer a detailed questionnaire as well as view a series of patterns on your screen and respond to questions about their orientation. Your responses will be used to evaluate your visual contrast sensitivity.

What can the results of VCS testing indicate?

A positive VCS test result, combined with other clinical findings, may suggest the possibility of mold exposure and the need for further investigation and treatment. However, it's important to note that VCS testing alone is not a definitive diagnostic tool for mold toxicity.

How do I know if VCS testing is right for me?

If you suspect mold exposure and are experiencing symptoms that could be related to mold toxicity, it's important to consult with a healthcare professional who specializes in environmental medicine or mold-related illnesses. They can help determine if VCS testing or other diagnostic tests are appropriate for your situation.

What should I do if I test positive on a VCS test?

If you test positive on a VCS test and suspect mold exposure, it's important to follow up with our Mold and CIRS specialiasts who can provide further evaluation and treatment recommendations. They may recommend additional tests or treatments based on your individual circumstances.
