Both forms are water soluble, aqueous fixatives should be avoided
Absolute ethanol is the fixative of choice
Gout – monosodium urate crystals appear yellow when their long axes are aligned parallel to a red compensator filter
Pseudogout -calcium pyrophosphate crystals, appear blue when their long axes are aligned parallel to a red compensator filter
