Did you know? VCS is the most sensitive indicator of effects from many toxins either because the visual system is highly susceptible to neurotoxins or because even small deficits in VCS can be measured.

System Requirements
In addition to having a live Internet Connection, this site requires the following:
Display/Video Card:
To properly view the VCS Exam, your video card must support at least 8-bit color. To check if your video card supports 8-bit color:
1. Right Click on the desktop
2. Choose Properties.
3. Choose the Settings tab.
4. Under Colors:
a.) If you only see 256 color then you will need to try taking the VCS Exam on a another computer with more colors.
b.) If you see 16-bit or greater, select it and follow the instructions.
SSL Enabled Browser:
In order to purchase exams online and view sensitive data, your browser must be able to maintain a secure connection. Most versions of Internet Explorer and Netscape have this ability.

We highly recommend using Internet Explorer 5.x or later for optimal display.
 
Macromedia Flash Player:
To complete the VCS Exam online, you must have the Macromedia Flash Player correctly installed. Most computers ship with this player already installed. If you are unsure, the VCS Exam page will automatically detect whether or not this component is installed. If it is not, you will be prompted to download the player from Macromedia, Inc. This component is freely distributed and requires very little disk space.

Prior to launching a new version of this website in June, 2002, the earlier version had been online for about a year and a half. Over 3,600 registered users had taken the preliminary and VCS tests. About half of the test results were positive for potential chronic, neurotoxin-induced illness. We do not know exactly how many of those used our treatment protocol with their local physician, or the outcome for all that did. We do know, however, that many used the protocol with success, and that many others were successfully treated by Dr. Shoemaker or another physician.
