Bilirubin is a yellow compound. It forms when red blood cells break down. This process happens in the liver. Bilirubin travels in the blood. The body usually gets rid of bilirubin through stool. Newborns can have high bilirubin levels. This condition is called jaundice.
Why is Bilirubin Important?
Bilirubin is a waste product. High levels of bilirubin are dangerous. They can lead to brain damage. This condition is known as kernicterus. Monitoring bilirubin is crucial for newborn health.
Types of Bilirubin
Bilirubin has two main forms:
Unconjugated (indirect) bilirubin.
Conjugated (direct) bilirubin.
Unconjugated bilirubin is fat-soluble. It is not water-soluble. The liver converts it into a water-soluble form. This process makes it easier to excrete. Conjugated bilirubin is water-soluble. It is excreted in bile and leaves the body through stool.
How is Bilirubin Measured?
A blood test measures bilirubin levels. This test is called a bilirubin test. The blood sample is taken from the baby’s heel. The blood is then analyzed in a lab. Results show the total bilirubin level. They also show the levels of unconjugated and conjugated bilirubin.
Causes of High Bilirubin Levels in Newborns
There are several reasons for high bilirubin levels:
Physiological Jaundice: Most common. It appears two to four days after birth. It is usually mild and goes away on its own.
Breastfeeding Jaundice: Caused by dehydration or low calorie intake.
Breast Milk Jaundice: Substances in breast milk can cause bilirubin levels to rise.
Hemolytic Disease: Blood type incompatibility between mother and baby.
Internal Bleeding: Bruising during birth can cause high bilirubin levels.
Liver Problems: The liver might not process bilirubin properly.
Infections: Infections can increase bilirubin levels.
Symptoms of High Bilirubin Levels
Jaundice is the main symptom. The baby’s skin and eyes turn yellow. Other symptoms include:
Poor feeding
Lethargy
High-pitched crying
Dark urine
Pale stools
Diagnosis of High Bilirubin Levels
A physical exam checks for jaundice. Blood tests confirm the bilirubin level. The tests measure total, direct, and indirect bilirubin. A transcutaneous bilirubinometer can also be used. This device measures bilirubin through the skin.

Treatment of High Bilirubin Levels
Treatment depends on the bilirubin level and the baby’s age. Options include:
Phototherapy: The baby is placed under special lights. Light helps break down bilirubin.
Exchange Transfusion: This is for severe cases. The baby’s blood is replaced with donor blood.
Intravenous Immunoglobulin (IVIg): Used if jaundice is due to blood group incompatibility.
Enhanced Nutrition: More frequent feedings help reduce bilirubin levels.
Prevention of High Bilirubin Levels
Breastfeed frequently. This helps the baby pass stool more often. Stool helps remove bilirubin. Monitor the baby’s feeding and output. Ensure the baby is gaining weight.
Complications of High Bilirubin Levels
High bilirubin levels can cause serious complications:
Acute Bilirubin Encephalopathy: Early stage of brain damage. Symptoms include lethargy, high-pitched crying, and poor feeding.
Kernicterus: Severe form of brain damage. It can lead to hearing loss, cerebral palsy, and intellectual disabilities.
When to Seek Medical Attention
Seek medical help if the baby shows signs of jaundice. Watch for yellowing of the skin and eyes. Monitor the baby’s feeding and behavior. If the baby is very sleepy or not feeding well, see a doctor.
Conclusion
Bilirubin is a byproduct of red blood cell breakdown. High levels can be dangerous for newborns. Monitoring and managing bilirubin levels is crucial. Early detection and treatment prevent complications. Parents should be aware of jaundice symptoms. Regular check-ups ensure the baby’s health and well-being.
FAQs
What is a Normal Bilirubin Level in a Newborn?
The normal bilirubin level for a newborn can vary depending on their age and the method of measurement. Generally, the following guidelines are used:
At birth: Total bilirubin levels are typically less than 6 mg/dL (milligrams per deciliter).
1-2 days after birth: Bilirubin levels can rise, with a normal range being up to 12-15 mg/dL.
After 2-3 days: Levels might peak and then begin to decline. By the end of the first week, levels should generally fall below 12-15 mg/dL.
These values are general estimates and can vary based on factors such as prematurity and overall health. Always consult a healthcare provider for specific guidance related to an individual newborn.
What Does a Bilirubin Test Mean for Newborns?
A bilirubin test measures the amount of bilirubin in the blood. Bilirubin is a byproduct of the normal breakdown of red blood cells. In newborns, this test is used to evaluate:
Jaundice: A common condition in newborns where the skin and eyes turn yellow due to high bilirubin levels.
Liver Function: High bilirubin can indicate liver dysfunction or other issues.
Hemolytic Conditions: Conditions where red blood cells are broken down too quickly, such as Rh or ABO incompatibility.
The test usually measures:
Total Bilirubin: The sum of unconjugated (indirect) and conjugated (direct) bilirubin.
Direct (Conjugated) Bilirubin: The water-soluble form that the liver processes.
Indirect (Unconjugated) Bilirubin: The fat-soluble form that is converted by the liver.
What If Total Bilirubin is High in Newborns?
High total bilirubin levels can indicate various conditions. The implications depend on the level of bilirubin and the baby’s age:
Physiological Jaundice: Most common and usually benign. It often resolves on its own as the baby’s liver matures.
Breastfeeding Jaundice: Caused by inadequate feeding. It usually improves with more frequent feedings.
Breast Milk Jaundice: Caused by substances in breast milk. This type can persist for several weeks but is usually harmless.
Hemolytic Disease: Conditions like Rh or ABO incompatibility can cause high bilirubin. Treatment may be needed to prevent serious complications.
Liver Disorders: Conditions affecting the liver’s ability to process bilirubin can lead to high levels. Further diagnostic testing and treatment might be required.
Treatment is determined based on the cause, the bilirubin level, and the baby’s overall condition.
How Do You Clear Bilirubin in a Newborn?
Clearing high bilirubin levels involves several strategies:
Phototherapy: This is the most common treatment. The baby is placed under special blue lights that help break down bilirubin in the skin. This process helps the body excrete the substance more effectively.
Exchange Transfusion: For severe cases, this procedure involves replacing some of the baby’s blood with donor blood. It helps reduce bilirubin levels quickly.
Intravenous Immunoglobulin (IVIg): If the high bilirubin is due to blood group incompatibility, IVIg may help reduce bilirubin levels and improve the baby’s condition.
Enhanced Nutrition: Frequent breastfeeding helps ensure the baby gets enough fluids and calories, which promotes bowel movements. This helps eliminate bilirubin through stool.
Monitoring and Follow-Up: Regular monitoring of bilirubin levels is essential. In some cases, bilirubin levels may return to normal with proper feeding and hydration.
It’s important to consult healthcare providers for the best course of action based on the baby’s specific condition and bilirubin levels.
