The birth of a baby is a joyful occasion, but it’s also a time when parents must remain vigilant about their newborn’s health. Among the many medical tests a baby undergoes after birth, the bilirubin blood test is one of the most critical. This test helps detect jaundice, a common condition in newborns caused by high bilirubin levels.
In this blog, we’ll look into the normal bilirubin level in newborns, the bilirubin levels chart, and how understanding the normal range of bilirubin in newborns is vital for their health. At Dr. B. Lal Lab, we provide precise diagnostics to ensure the best start for your baby’s life.
Bilirubin is a yellow pigment produced during the natural breakdown of red blood cells. The liver processes this pigment, which is then excreted through the stool.
In newborns, however, the liver is often still maturing and may not efficiently process bilirubin. This can result in higher bilirubin levels, leading to jaundice, characterized by yellowing of the skin and eyes. While mild jaundice is common and usually harmless, severe cases require immediate medical attention.
The bilirubin blood test measures the amount of bilirubin in a baby’s blood to identify jaundice and assess its severity. Early detection is crucial because untreated high bilirubin levels can lead to complications like kernicterus, a rare but serious form of brain damage.
The normal bilirubin level in newborns varies based on their age in hours or days. Typically, the levels are:
These ranges represent the upper limits of normal bilirubin levels.
The normal range of bilirubin in newborns can vary slightly depending on the method of measurement and the baby’s specific health condition. In general:
A bilirubin levels chart is an essential tool used by healthcare professionals to assess and manage jaundice.
The American Academy of Pediatrics uses a jaundice level chart to assess whether a newborn needs treatment, based on the baby's serum bilirubin level and age.
| 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.

Q1: What is bilirubin?
A: Bilirubin is a yellow pigment that is produced when red blood cells break down. It’s normally processed by the liver and excreted in stool.
Q2: Why is a bilirubin test important for newborns?
A: A bilirubin test is important for newborns to check for jaundice, a condition caused by high levels of bilirubin in the blood. Untreated jaundice can lead to serious health problems.
Q3: How is a bilirubin test performed?
A: A bilirubin test can be performed through a blood test or using a non-invasive device called a transcutaneous bilirubinometer.
Q4: Can I get a bilirubin test at Dr. B. Lal Lab?
A: Yes, Dr. B. Lal Lab offers bilirubin testing for newborns. They have state-of-the-art facilities and experienced professionals to ensure accurate and timely results.
