An unhealthy bilirubin level is generally considered to be above 1.2 mg/dL in adults and above 1.0 mg/dL in children aged 15 days to 18 years. However, levels significantly above these values indicate a more serious issue. Levels exceeding 2.5 mg/dL in adults are often associated with jaundice. In newborns, extremely high bilirubin levels (over 25 mg/dL) can lead to severe complications like cerebral palsy or deafness.
Understanding Bilirubin Levels
Bilirubin is a yellowish pigment produced during the breakdown of red blood cells. Normal levels are generally kept low. Elevated levels signal potential problems within the liver, blood, or other systems.
Healthy Ranges:
- Adults: Typically 0.2 to 1.2 mg/dL
- Children (15 days - 18 years): Less than 1.0 mg/dL
Unhealthy/Elevated Ranges:
- Adults: Above 1.2 mg/dL, with levels above 2.5 mg/dL often indicating jaundice and a need for further investigation.
- Children (15 days - 18 years): Above 1.0 mg/dL. High levels in newborns require immediate medical attention.
- Newborns (extreme): Above 25 mg/dL can cause serious neurological damage.
Causes of Elevated Bilirubin
High bilirubin can stem from various conditions, including:
- Liver disease: Cirrhosis, hepatitis, etc.
- Gallbladder problems: Blockages, stones
- Blood disorders: Anemia, sickle cell disease
- Genetic conditions: Gilbert's syndrome, Crigler-Najjar syndrome
- Certain medications: Some drugs can affect bilirubin metabolism.
