The following is the procedure for identifi-
cation of pseudo gout:
The test for pseudo gout is done identically to
the test for gout. However, the color change is
opposite that of Gout. That is, with the handle at
the left extreme, aligned crystals are blue and
perpendicular crystals are yellow, and vice
versa with the level at the right side (Fig. 69).
