The disease porphyria has been questioned in blue urination color. Porphyria is a combination of eight or more disorders that have various symptoms, they all share one symptom-they create the accumulation of porphyrins inside of the body. The word porphyria comes from the Greek word porphyrus meaning purple. You’re urine can actually turn purple with this disorder. The hue or tinge can be anywhere from red or purple in color. However, usually not blue. For some, the difference between red or purple and blue may be difficult to ascertain.
