The normal range for bilirubin varies slightly between laboratories, but generally falls between 0.2 to 1.2 mg/dL.
Here's a more detailed breakdown:
Bilirubin Levels: A Closer Look
Bilirubin is a yellow pigment found in bile, a fluid made by the liver. Bilirubin testing helps to assess liver function and diagnose certain conditions.
Normal Bilirubin Ranges
| Type of Bilirubin | Normal Range (mg/dL) | Notes |
|---|---|---|
| Total Bilirubin | 0.2 - 1.2 | For adults, this is the overall bilirubin level. |
| Total Bilirubin (Children Under 18) | Around 1.0 | Expected for those younger than 18. |
| Direct Bilirubin | 0.3 | This refers to conjugated bilirubin, often associated with liver and bile duct issues. |
Key Points to Remember:
- Laboratory Variation: Bilirubin ranges can vary slightly between different laboratories, so it's best to interpret results with your doctor's guidance.
- Age Considerations: Bilirubin levels in children under 18 are typically lower than adults, with 1 mg/dL often being considered the upper limit.
- Direct vs. Total: Direct bilirubin, which is also known as conjugated bilirubin, has a specific normal range (around 0.3 mg/dL), and it can be helpful to distinguish it from the total bilirubin level.
- Interpretation is Key: Elevated bilirubin levels can indicate underlying issues such as liver disease, bile duct obstruction, or hemolytic anemia.
Practical Insights:
- A blood test is used to measure bilirubin levels.
- High bilirubin can cause jaundice, characterized by yellowing of the skin and eyes.
- It is crucial to consult with a healthcare professional for proper diagnosis and treatment.
