A case of green urine in the qualitative analysis of urinary protein caused by elevated urinary copper in a patient with choledochal adenocarcinoma
A middle-aged female with abnormal liver function indicators was admitted to hospital with obstructive jaundice.Urine protein of the patient was positive,and the color turned green during the retest with sulfosalicylic acid,which was relatively rare.According to the laboratory examination and other auxiliary diagnosis of the patient,the cause of the discoloration was found to be obstructive jaundice induced by choledochal adenocarcinoma,which impeded the excretion of copper ions through the bile of the patient.Copper enters the urine through the circulation of the bile,causing an increase in urinary copper.This provides a theoretical basis for the discovery of this phenomenon in clinical tests.
