1. What Is Bilirubin?

Bilirubin is a yellow pigment produced during the normal breakdown of red blood cells. It is processed by the liver and excreted in bile. Elevated levels may indicate liver dysfunction or hemolytic disorders.

2. How Does The Conversion Work?

The conversion uses the formula:

Where:

• \( \mu mol/L \) — Bilirubin concentration in micromoles per liter
• \( 0.58466 \) — Molecular weight conversion factor (g/mmol)
• \( / 10 \) — Conversion from mg/L to mg/dL

Explanation: This formula converts bilirubin values from the SI unit (μmol/L) to the conventional unit (mg/dL) commonly used in clinical practice.

3. Importance Of Bilirubin Measurement

Details: Bilirubin measurement is crucial for diagnosing and monitoring liver diseases such as hepatitis, cirrhosis, and biliary obstruction, as well as hemolytic conditions like jaundice.

4. Using The Calculator

Tips: Enter bilirubin value in μmol/L. The value must be a positive number. The calculator will automatically convert it to mg/dL with two decimal places precision.

5. Frequently Asked Questions (FAQ)

Q1: Why convert bilirubin from μmol/L to mg/dL?
A: Different countries and laboratories use different units. Conversion allows comparison of results and facilitates international medical communication.

Q2: What are normal bilirubin values?
A: Normal total bilirubin is typically 0.2-1.2 mg/dL (3.4-20.5 μmol/L). Values above this range may indicate liver disease or hemolysis.

Q3: When should bilirubin be measured?
A: Bilirubin testing is indicated when patients show signs of jaundice (yellow skin/eyes), dark urine, or when monitoring known liver conditions.

Q4: Are there different types of bilirubin?
A: Yes, bilirubin exists as unconjugated (indirect) and conjugated (direct) forms. The conversion applies to total bilirubin measurement.

Q5: How accurate is this conversion?
A: The conversion uses the precise molecular weight of bilirubin (584.66 g/mol) and provides clinically accurate results for medical purposes.
