Question

How to calculate direct bilirubin from total bilirubin?

Answer 1

Answer:

Total bilirubin = 0.3 to 1.0 mg/dL or 5.1 to 17.0 mmol/L.

Direct bilirubin (conjugated bilirubin) = 0.1 to 0.3 mg/dL or 1.0 to 5.1 mmol/L.

Indirect bilirubin (unconjugated bilirubin) = (total bilirubin minus direct bilirubin level) = 0.2 to 0.7 mg/dL or 3.4 to 11.9 mmol/L.

Answer 2

Answer:

Bilirubin-

It is a pigment that is yellow in color produced when the Red Blood Cells(RBC) get normally broken down.

Explanation:

Normal Values of bilirubin:

• Total bilirubin = 0.3 to 1.0 mg/dL (5.1 to 17.0 mmol/L)
• Direct bilirubin = 0.1 to 0.9 mg/dL (1.0 to 5.1 mmol/L)
• Indirect bilirubin = 0.2 to 0.7 mg/dL (3.4 to 11.9 mmol/L)

To calculate direct bilirubin from total bilirubin

1. Total bilirubin = Direct bilirubin + Indirect bilirubin
2. Direct bilirubin = Total bilirubin - Indirect bilirubin
3. Indirect bilirubin = Total bilirubin - Direct bilirubin
