Bilirubin Conversion Formula:
| From: | To: |
Bilirubin is a yellow pigment formed during the breakdown of red blood cells. It is processed by the liver and excreted in bile. Measuring bilirubin levels helps assess liver function and diagnose conditions like jaundice, hepatitis, or bile duct obstruction.
The conversion from mg/dL to μmol/L uses the formula:
Where:
Explanation: The formula accounts for the molecular weight difference between measurement units, providing accurate conversion between mg/dL and μmol/L for bilirubin.
Details: Bilirubin levels are crucial indicators of liver health and hemolytic processes. Elevated levels may indicate liver disease, bile duct obstruction, or hemolytic anemia, while monitoring helps track treatment effectiveness.
Tips: Enter bilirubin value in mg/dL. The value must be greater than zero. The calculator will automatically convert to μmol/L using the standard conversion formula.
Q1: Why convert bilirubin from mg/dL to μmol/L?
A: Different countries and laboratories use different units. Conversion ensures consistent interpretation of results across various medical settings.
Q2: What are normal bilirubin levels?
A: Normal total bilirubin is typically 0.1-1.2 mg/dL (1.7-20.5 μmol/L). Levels above this range may indicate underlying health issues.
Q3: When should bilirubin be measured?
A: Bilirubin testing is indicated when jaundice is present, when monitoring liver diseases, or as part of routine liver function tests.
Q4: Are there different types of bilirubin?
A: Yes, bilirubin is measured as total, direct (conjugated), and indirect (unconjugated) forms, each providing different clinical information.
Q5: How does bilirubin relate to newborn jaundice?
A: Newborns commonly have elevated bilirubin due to immature liver function. Monitoring levels helps prevent kernicterus, a serious complication.
