The delivery of a child marks an instance of immense joy, yet it is important to be on the lookout for any possible risks that might endanger the health of your newborn baby. Bilirubin blood test forms one of the most essential medical tests to help diagnose possible cases of jaundice – a condition associated with excess production of bilirubin in babies.
This article will seek to highlight what the bilirubin normal range in a newborn is, as well as the bilirubin level chart to show the importance of knowing the normal range of bilirubin in newborn. We, at Dr. B. Lal lab, offer accurate diagnosis services to give your baby the best start to his/her life.
The yellow pigment known as bilirubin is formed when red blood cells break down. It is processed in the liver and eliminated from the body via feces.
But in the case of infants, their livers have yet to fully develop and might be unable to process bilirubin effectively. This leads to increased bilirubin levels, causing jaundice, wherein the baby's skin and eyes turn yellow. Mild cases of jaundice are normal, but severe cases need medical intervention.
The bilirubin test involves determining the bilirubin levels in the blood of a baby to detect the presence of jaundice and determine its severity. It is important that jaundice be detected early since failure to do so can result in serious conditions such as kernicterus.
The normal bilirubin level in newborn varies based on their age in hours or days. Typically, the levels are:
These ranges represent the upper limits of normal bilirubin levels.
The new born baby bilirubin normal range can vary slightly depending on the method of measurement and the baby’s specific health condition. In general:
A bilirubin level chart is an important tool for physicians who want to determine and treat jaundice cases.
According to the American Academy of Pediatrics, a jaundice level chart can be used to determine whether a baby requires treatment using the serum bilirubin levels and age of the infant
| Total serum bilirubin (TSB) level | Age of newborn |
| Above 10 milligrams | Less than 24 hours old |
| Above 15 milligrams | 24 to 48 hours old |
| Above 18 milligrams | 49 to 72 hours old |
| Above 20 milligrams | Older than 72 hours |
The specific thresholds for treatment, such as phototherapy or exchange transfusion, depend on the baby’s age, weight, and overall health.

Several factors can contribute to elevated bilirubin levels, including:
1. Physiological Jaundice: Common in the first week of life due to the immature liver.
2. Breastfeeding Jaundice: Caused by inadequate feeding or dehydration in the first few days.
3. Blood Group Incompatibility: Hemolysis due to Rh or ABO incompatibility between the baby and the mother.
4. Prematurity: Premature babies are at higher risk due to underdeveloped livers.
5. Infections: Certain infections can impair liver function and increase bilirubin levels.
6. G6PD Deficiency: A genetic condition affecting red blood cell breakdown.
Parents should watch for the following signs of jaundice:
If you notice these symptoms, consult your healthcare provider immediately.
Treatment depends on the bilirubin level, the baby’s age, and the underlying cause:
The bilirubin test can be done through:
A small sample of blood is taken from the baby’s heel.
A non-invasive device placed on the baby’s skin to measure bilirubin levels.
Our state-of-the-art diagnostic facilities ensure accurate and reliable bilirubin level testing for newborns.
We use cutting-edge methods for precise bilirubin measurement.
Our team ensures you understand the results and guides you through the next steps.
Quick turnarounds and easy scheduling prioritize your baby’s health and your peace of mind.
While not all cases of jaundice are preventable, some measures can reduce the risk:
Feed your baby at least 8–12 times a day to promote bilirubin excretion.
Keep an eye out for yellowing skin or changes in feeding patterns.
Routine visits to the pediatrician ensure early detection and management of jaundice.
