Question

If the total bilirubin is 3.1 mg/dL and the conjugated bilirubin is 2.0 mg/dl, the unconjugated bilirubin is:

a. 0.5 mg/dL
b. 1.1 mg/dL
c. 2.2 mg/dL
d. 5.1 mg/dL

Answer 1

The unconjugated bilirubin level is calculated by subtracting the conjugated bilirubin level from the total bilirubin level, yielding 1.1 mg/dL.Therefore, the correct answer is b. 1.1 mg/dL.

Step-by-step explanation:

To determine the unconjugated bilirubin level when the total bilirubin is 3.1 mg/dL and the conjugated bilirubin is 2.0 mg/dL, you would subtract the amount of conjugated bilirubin from the total bilirubin level. The calculation would be 3.1 mg/dL (total bilirubin) - 2.0 mg/dL (conjugated bilirubin) = 1.1 mg/dL (unconjugated bilirubin).

Therefore, the correct answer is b. 1.1 mg/dL.
