Hemolytic jaundice - excessive breakdown of red blood cells leads to a corresponding increase in conjugated bilirubin excreted by the liver, converted to urobilinogen in the intestines, and more urobilinogen being reabsorbed in the intestines which gets excreted in the urine.
It's the bilirubin found in an urinalysis.
Urobilinogen refers to the presence of bilirubin in the urine. Bilirubin is an enzyme that comes from the liver, and if it shows up in urine, that typically means that a person has a serious illness. The illness could be anything from gallstones to anemia, since bilirubin in the urine could be caused by many different things.
Bilirubin is the pigment that makes feces brown."Failure of the liver cells to excrete bile, or obstruction of the bile ducts, can cause an increased amount of bilirubin in the body fluids and thus lead to obstructive or regurgitation jaundice.Another type of jaundice results from excessive destruction of erythrocytes (hemolytic or retention jaundice). The more rapid the destruction of red blood cells and the degradation of hemoglobin, the greater the amount of bilirubin in the body fluids.Most bilirubin is excreted in the feces. A small amount is excreted in the urine as urobilinogen."answers.com
jaundice the normal serum bilirubin level is 0.5 to 1.5mg%. jaundice occurs when the bilirubin level exceeds 2mg%. the increased blood level of bilirubin is called hyperbilirubinemia. excess bilirubin from blood diffuses into the tissues, skin and mucous membrane, colouring them yellow. this condition caused by overflow of bilirubin is called jaundice.
Urobilinogen
Urobilinogen: Urobilinogen is normally present in urine at concentrations up to 1.0mg/dl. A result of 2.0mg/dl represents the transition zone from normal to abnormal and the patient and or urine specimen should be evaluated further for hemolytic and hepatic disease. Evaluation of both the bilirubin and urobilinogen results helps in the differential diagnosis of jaundice, as well as other liver and biliary disorders.
Newborn jaundice is caused when there are high bilirubin levels in the blood.
bilirubin
Yellow jaundice is not a disease but rather a sign that can occur in many different diseases. Jaundice is the yellowish staining of the skin and sclerae (the whites of the eyes) that is caused by high levels in blood of the chemical bilirubin. The color of the skin and sclerae vary depending on the level of bilirubin. When the bilirubin level is mildly elevated, they are yellowish. When the bilirubin level is high, they tend to be brown. White jaundice: old term for chlorosis
Check the bilirubin level.
Jaundice and carotenemia are the most common causes of yellow skin. Jaundice is accumulation of bilirubin which is a bile pigment and carotenemia is the accumulation of carotene; the precursor of vitamin A.
