What This Helps Measure
Free screening for mold/CIRS - reduced contrast sensitivity
Which theories this can evaluate
This measurement is most useful when your pattern already suggests why it belongs in the workup.
What It Does Not Prove
One biomarker rarely settles the full question on its own. It is most useful when the pattern already suggests why it matters.

VCS Test (Visual Contrast Sensitivity) Decision Map
Preparation, interpretation, and clinician next step for VCS Test (Visual Contrast Sensitivity).
Visual Guide
How To Prepare
- •Find a quiet room with consistent lighting.
- •If you wear glasses, take them off unless specifically instructed otherwise.
- •Avoid alcohol for 24 hours before testing.
How To Use This Test Well
Step 1
Book correctly
Request VCS Test (Visual Contrast Sensitivity) with required timing/prep (fasting and time-of-day when relevant).
Step 2
Capture the result exactly
Save numerical value, units, lab reference interval, and collection time.
Step 3
Interpret with pattern context
Compare results against symptom timing and related markers before changing plan.
What To Watch For
- →VCS can fail from many causes beyond mold: concussion, Lyme, certain medications, normal aging.
- →Online versions vary in quality and standardization.
- →One failure is suggestive but not diagnostic on its own.
Result Context
normal
Within lab range; compare with your target context (Pass/Fail).
Result may be acceptable but still needs symptom correlation and trend review.
borderline
Near thresholds or inconsistent with symptoms.
Consider repeat testing, timing factors, and related markers before conclusions.
abnormal
Outside expected range or clearly discordant with baseline.
Use clinician-guided follow-up and structured differential workup.
What To Do Next
- •If VCS fails, look for environmental correlation first (does it track with specific locations?).
- •Consider a formal vision exam to rule out other causes before pursuing CIRS workup.
