Identification of Crystals

Identification of crystals found in the urine sediment requires knowledge of the urinary pH.

Large crystals are identifiable under low power. High power magnification is required for smaller crystals.

Most crystals can be identified by morphology alone. Urine pH and reagent strip results can provide supporting information. If further examination is necessary birefringence and solubility characteristics should be performed.
