odd! Have you seen purple urine?

odd! Have you seen purple urine? According to a case report in the New England Journal of Medicine, a French woman was admitted to the hospital due to illness. After 10 days, the urine in her urine changed from a normal yellow to a strange purple. Under normal circumstances, if this happens, the doctor will doubt whether the patient has a urinary tract infection, but the test proves that the woman does not have symptoms such as urinary tract infection. The reason is that this strange purple urine is caused by a chemical reaction in the urine bag. Because the bacteria converts a chemical substance called indole sulfate in the urine into red and blue compounds, two When the colored compounds are mixed together, the urine turns purple. Indophenol sulfate is derived from tryptophan in the diet. This rare condition is called “purple urine bag syndrome”
