What feature describes Bilirubin Crystals?

Bilirubin crystals are characterized by their yellow to amber color, which is a key feature that can help differentiate them from other types of crystals that may be observed in urine. The presence of bilirubin in the urine often indicates some form of liver dysfunction or biliary obstruction, and the amber color signifies the buildup of bilirubin, a breakdown product of hemoglobin from red blood cells. This coloration assists veterinary professionals in diagnosing potential underlying health issues.

While other options may describe different types of crystals or characteristics associated with them, the amber color is directly tied to bilirubin, making it the most accurate descriptor for bilirubin crystals.
