1. What is Bilirubin Unit Conversion?

Bilirubin unit conversion involves transforming bilirubin concentration values between millimoles per liter (mmol/L) and milligrams per deciliter (mg/dL). This conversion is essential for medical professionals working with laboratory results from different measurement systems.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

\[ \text{mg/dL} = \frac{\text{mmol/L} \times 584.66}{10} \]

Where:

\( \text{mmol/L} \) — Bilirubin concentration in millimoles per liter
\( 584.66 \) — Molecular weight of bilirubin (g/mol)
\( 10 \) — Conversion factor for deciliters

Explanation: The formula accounts for the molecular weight of bilirubin and converts between the different concentration units used in medical laboratories.

3. Importance of Bilirubin Measurement

Details: Bilirubin measurement is crucial for diagnosing and monitoring liver diseases, bile duct obstructions, hemolytic disorders, and neonatal jaundice. Accurate unit conversion ensures proper interpretation of test results across different laboratory standards.

4. Using the Calculator

Tips: Enter bilirubin concentration in mmol/L. The value must be a valid number (≥0). The calculator will automatically convert to mg/dL using the standard conversion formula.

5. Frequently Asked Questions (FAQ)

Q1: Why is 584.66 used in the conversion?
A: 584.66 represents the molecular weight of bilirubin in grams per mole, which is necessary for converting between molar concentration (mmol/L) and mass concentration (mg/dL).

Q2: What are normal bilirubin levels?
A: Normal total bilirubin levels are typically 0.1-1.0 mg/dL (1.7-17.1 μmol/L). Values above this range may indicate liver dysfunction or other medical conditions.

Q3: When is bilirubin testing performed?
A: Bilirubin testing is performed when liver disease, bile duct obstruction, or hemolytic anemia is suspected, and for monitoring neonatal jaundice.

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

Q5: How accurate is this conversion?
A: The conversion is mathematically precise based on bilirubin's molecular weight. However, laboratory methods may have slight variations in measurement accuracy.
