Question

Reference values for Conjugated Bilirubin in serum are typically in the range of:

a) 0.1-0.5 mg/dL
b) 0.6-1.2 mg/dL
c) 1.3-2.0 mg/dL
d) 2.1-3.0 mg/dL

Answer 1

The typical reference values for Conjugated Bilirubin in serum fall between 0.1-0.5 mg/dL. Elevated levels of conjugated bilirubin are often associated with obstructive jaundice, while disorders like Gilbert's syndrome can increase unconjugated bilirubin.

Step-by-step explanation:

The reference values for Conjugated Bilirubin in serum are typically in the range of 0.1-0.5 mg/dL, which corresponds to option a) 0.1-0.5 mg/dL. Bilirubin is a pigment found in bile, a substance produced by the liver. There are two forms of bilirubin: unconjugated (indirect) and conjugated (direct). Increased levels of either form can indicate various health issues. In conditions such as obstructive jaundice, there is an elevation of conjugated bilirubin due to obstruction in the bile ducts. On the other hand, conditions that affect the liver's ability to handle bilirubin, such as hepatic jaundice, Gilbert's syndrome, or Crigler-Najjar syndrome, typically result in raised levels of unconjugated bilirubin in the blood.
