Answer:
Unconjugated bilirubin is a type of bilirubin that is not water-soluble and is bound to a protein called albumin in the blood . Increased levels of unconjugated bilirubin in the serum can indicate a variety of conditions, including hemolytic anemia, Gilbert’s syndrome, and Crigler-Najjar syndrome . Gilbert’s syndrome is a mild condition where the liver does not process bilirubin properly due to abnormality of the responsible liver enzyme . Crigler-Najjar syndrome is a rare genetic disorder that causes high levels of unconjugated bilirubin in the blood, leading to jaundice and other complications . If you are experiencing new, severe, or persistent symptoms, it is recommended that you contact a health care provider .
