How do you screen for CIRS? 1) You ask the 37 symptoms in 13 groups, known as “cluster symptoms”. 2) You combine this with a Visual Contrast Sensitivity test. These two screenings get you to a 1 in 50 chance you’re wrong about the CIRS diagnosis. 3) Then you follow this with specific confirmatory labs, which we discuss on the podcast.
Once you are confirmed CIRS, you move forward with the CIRS/Shoemaker protocol. Dr. D published a paper on this last summer with all the details and it’s available to anyone online.
Want to hear more? We recorded an entire podcast episode discussing CIRS, genetics, biotin exposure, evidence-based testing, the shoemaker protocol, and more. Comment “CIRS” and I’ll send you a link to the episode.
