LOINC description : Red-green and blue-yellow color blindness are tested using the Neitz Test of Color
Vision, a disposable 1-page test which consists of 1 demonstration and 8 test panels.
In each plate, colored dots of three different sizes and two different saturations
form the outline of a geometrical shape. The shapes, presented as multiple choices,
are a circle, a square, a triangle, a diamond, and nothing. The examinee marks the
option that represents what he or she sees in the grey dot pattern. Because the test
is a precisely calibrated instrument, reproductions of the forms will not yield satisfactory
results. Color copiers cannot adequately reproduce the colors that are necessary for
the test to yield a valid classification. Furthermore, the test is copyrighted and
proprietary and it is therefore impermissible to photocopy test materials for reuse.
