Procedure |
Calcium | Black deposits formed when using silver reactions are due to reduction of silver by organic material followed by exposure to strong light | Calcium Stain
Control Slides |
Procedure |
Urates |
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
