👉 The auburn fluid, also known as auburn blood or auburn urine, refers to the reddish-brown color that can appear in certain bodily fluids, particularly urine, when it contains a higher concentration of bilirubin. This pigment is primarily produced by the breakdown of red blood cells in the liver, and when it enters the bloodstream, it can give urine its characteristic auburn hue. This condition is often associated with liver disorders, hemolysis (the premature destruction of red blood cells), or other conditions that increase bilirubin levels. While usually harmless, it can be a sign of underlying health issues and should be evaluated by a healthcare professional.
