Direct bilirubin in neonates
What is the cause of elevated indirect bilirubin levels?
Causes of increased levels of indirect bilirubin. Increased or elevated levels of indirect form of bilirubin may be caused by increased production of the substance or decreased conjugation. Hyperbilirubinemia is the increased level of bilirubin in body.
What is the normal level of bilirubin in newborn?
Normal values of total bilirubin are from 0.3–1.0 mg/dL. The indirect bilirubin level in the bloodstream is the total bilirubin minus the direct bilirubin levels in the bloodstream. Additionally, normal reference ranges may vary from lab to lab. In a newborn, higher bilirubin is normal due to the stress of birth.
What is normal range of indirect bilirubin?
Normal values of direct bilirubin range from 0 to 0.4 mg/dL. Total bilirubin (direct and indirect) range from about 0.2 to 1.2 mg/dL (some lab values range as high as 1.9 mg/dL). Medical literature sources have minor variations in "normal" levels).
What is the difference between direct and indirect bilirubin?
The key differencebetween the Direct and Indirect bilirubin is that direct bilirubin is the bilirubin that is conjugated with glucuronic acid while the indirect bilirubin is not conjugated to the liver and it attaches to the carrier protein albumin. What is Direct Bilirubin? Direct bilirubin is covalently modified indirect bilirubin.
