What are the normal bilirubin levels in newborns? Common bilirubin levels in infant newborns: 1 day after birth: direct 0.2, indirect 3.5 mg/dl, total is 3.7 2 days: direct 0.3, indirect 5.0, and total is 5.3 1 week to 10 days after birth: indirect 13.0, direct 1.0, and total bilirubin 14.0 mg/dl.
What could be causing elevated direct bilirubin levels?
The most common causes of increased conjugated bilirubin levels are related to liver problems. Hepatitis: Damage to liver cells caused by inflammation can increase direct bilirubin levels. cirrhosis of the liver: Diseases such as alcoholism or certain viruses can cause liver cells to replace scar tissue; severe cirrhosis causes jaundice.
How to calculate indirect bilirubin?
- Without an accelerator (alcohol), mainly conjugated bilirubin is measured (direct reaction).
- Accelerator permits unconjugated bilirubin to react as well, providing total bilirubin.
- Indirect bilirubin is calculated as follows: Indirect bilirubin = Total bilirubin – direct bilirubin.
What is the normal range of unconjugated bilirubin?
Unconjugated (indirect) bilirubin: The normal reference range for unconjugated bilirubin level in adults is 0.2-0.8 mg/dL (also expressed as 3.4-12.0 mmol/L) Jaundice is a result of elevated bilirubin level in the blood (also known as hyperbilirubinemia).
