|Visual Contrast Sensitivity Test|
This page contains educational material about the Visual Contrast Sensitivity test(VCS). This test is a screening tool to identify possible biotoxin illness.. This information is for educational purposes only. Nothing in this text is intended to serve as medical advice. All medical decisions should be made only with the guidance of your own personal medical authority. I am doing my best to get this data up quickly and correctly. If you find errors in this data, please let me know.
Dr. Ritchie Shoemaker (physician who has done years of mold research) has used the Visual Contrast Sensitivity (VCS) test extensively as a screening tool in his practice. Many other physicians now use it similarly.
This test detects neurotoxicity in the optic nerve pathways. This correlates with the patients biotoxin burden. It can be executed in the physician's office or an easier method is to use an online option that is available at Dr. Shoemakers website: survivingmold.com Physicians can also purchase the in office VCS kit at the Surviving Mold website.
Dr. Shoemaker says 8% of people who have CIRS will have a normal VCS test. Therefore it is not a full proof screening tool. The physician must catch those 8% by their signs, symptoms, their history and the use of additional tests.
Although there are many false negatives, there are less than 1% false positives.
In my opinion this test is a very useful screening tool and easy to use since it can be performed online.
