One of the resulting parameters from the Color Blind Check app, the PDT score (abbreviated from Protan-Deutan-Tritan) shows probability (out of ten) that the individual has each type of CVD. For example:
- A certain Deutan has a PDT score of [0-10-0].
- A red-green colorblindness that could be either Protan or Deutan could have a PDT score of [5-4-0].
- An indeterminate for of colorblindness could have a PDT score of [3-4-3].
The PDT score communicates uncertainty in the results, which is a major advantage of CBC over other self-administered Colorblind Tests. It does not infer that the individual has multiple forms of CVD.
