Pizza is a common fast food category in the United States, with chains such as Papa John's, Domino's Pizza, Sbarro and Pizza Hut. Menus are more limited and standardized than in traditional pizzerias, and pizza delivery, often with a time commitment, is offered.
Leucine crystals in Urine. 1  Leucine crystals are abnormal in urine.  Appearance: yellow-brown spheroids with concentric rings around the outer edge and radial striations in the center.
Amorphous crystals. Amorphous crystals are frequently seen in urine from various species. This is a generic and quite non-specific term and just indicates small crystals that are not identifiable as to source. Some could represent fragmentation of larger crystals. The pH of the urine can be a guide as to the likely nature of the amorphous crystals (e.g. amorphous phosphates are more likely in alkaline urine in small animal patients). The main issue with amorphous crystals is that they mimic bacterial cocci (and even undergo brownian movement in urine).
