Introduction

BioGnost’s Ehrlich aldehyde reagent is used for detecting urobilinogen in urine. Urobilinogen is a chemical compound created by bilirubin reduction. Bilirubin is a pigmented bile constituent comprised of bile acid, phospholipids, bile salt, cholesterol, calcium, inorganic electrolytes, and bilirubin pigments. Most bilirubin (85%) are created from the hemoglobin of worn-out erythrocytes in the reticuloendothelial system.
