Neonatal hyperbilirubinemia or neonatal jaundice is a cause of concern for the first seven days in a baby. It’s development is observed in around 8 - 11% of neonates. Neonatal hyperbilirubinemia denotes a high level of bilirubin that can be toxic for the development of the central nervous system. About 60% of the cases of high bilirubin levels in the first seven days in babies are benign and get okay without any intervention. About 5 - 10% of cases of hyperbilirubinemia in babies require the use of phototherapy for its treatment. This article explores neonatal jaundice, normal range of bilirubin in babies, and the difference between physiological and pathological jaundice.
Normal Range of Bilirubin in Newborn Babies
The normal range of bilirubin in newborn babies is approximately 0.3 mg/dl to 1.0 mg/dL within the first 24 hours of birth. The level of bilirubin which is referred to as critical for the baby and when phototherapy is given for treatment is:
- 25 - 48 hours old: total serum bilirubin level above 15 mg/dL
- 49 - 72 hours old: total serum bilirubin level above 18 mg/dL
- > 72 hours old: total serum bilirubin level above 20 mg/dL
Physiological Jaundice vs Pathological Jaundice
Physiological jaundice:
It is the most common type of neonatal hyperbilirubinemia without any serious consequences. The bilirubin in physiological jaundice is generally in unconjugated form and it’s levels in the serum are less than 15 mg/dL. Physiological jaundice appears 24 - 72 hours after the birth. The levels of bilirubin in this condition are at their peak on the 4th or 5th day after birth and finally disappear when the baby is 10 - 14 days old.
Pathological Jaundice:
When the bilirubin levels in a newborn baby exceed a level such that intervention is required is known as pathological jaundice. In this, the levels of serum bilirubin go beyond 5 mg/dL/day within 24 hours of birth.
Takeaway
Neonatal jaundice is an extremely common condition appearing in the first seven days of life. This requires careful monitoring of the baby for the first week. In mild cases, it gets treated on its own, and in severe cases, phototherapy can effectively treat jaundice. Now that you know well about neonatal hyperbilirubinemia, you can better monitor your baby in the first few days of their life.
Frequently Asked Questions (FAQs)
-
How can I reduce the bilirubin level of my baby?
The bilirubin levels in the first few days of your baby’s life is a very critical parameter. In the case of hyperbilirubinemia, phototherapy, exchange transfusion, intravenous immunoglobulin, and enhanced nutrition can help in reducing the bilirubin levels.
-
Can bilirubin level rise back after phototherapy?
Yes, the bilirubin levels can rise back after phototherapy in some rare cases. In such a situation, follow-up and other treatment options are also considered for the baby.
-
Is phototherapy a safe treatment option for hyperbilirubinemia?
Yes, phototherapy is a very safe and effective treatment option for hyperbilirubinemia as it does not contain any rays that can harm your baby. The treatment is most effective when the maximum skin of the baby is exposed to the light.
-
Is 19 mg/dL considered as a high bilirubin level in newborns?
When the total serum bilirubin level rises by more than 5 mg/dL/day or if the level is above 17 mg/dL during the first 24 hours after the birth, the baby is known to suffer from hyperbilirubinemia.

A bilirubin level of 18.95 in a 4-day-old baby is high, and weight loss from 2.7 kg to 2.5 kg is concerning. Ensure frequent feeding, expose her to mild sunlight, and monitor for symptoms like yellowing of the skin. It's important to consult a pediatrician immediately for appropriate treatment, such as phototherapy.

My baby's age is 13 days and her bilurubin is 11.68. Can you please suggest me what should I do. She born in 38 weeks by C-section and her weight is 2.8kg. Please reply ASAP.
Myhealth Team
Nov 15, 2024 at 6:14 AM.
A bilirubin level of 11.68 in a 13-day-old baby is slightly elevated, but it's important to monitor her closely. Since your baby was born by C-section, it’s common for some jaundice to occur. However, it’s crucial to consult your pediatrician for advice on whether treatment is needed, as bilirubin levels can vary. Your doctor may recommend measures like increased feeding to help reduce bilirubin or, in some cases, phototherapy.

It's normal to worry about your baby's jaundice. Your blood type (O+) and your baby's (A+) usually aren't a concern for jaundice. A bilirubin level of 15 mg/dL indicates treatment is needed, and phototherapy is a common and effective approach. Ensure your baby feeds well, as this helps lower bilirubin levels. If you have concerns about blood type compatibility, discuss them with your pediatrician. You're doing well by seeking help, so continue to follow your healthcare provider's advice.

A bilirubin level of 18 in a 7-day-old baby is relatively high and may require immediate attention. Phototherapy is often recommended for elevated bilirubin levels to prevent complications like kernicterus. It’s crucial to consult your pediatrician right away for an accurate assessment and appropriate treatment. They will determine the necessity and urgency of phototherapy based on your baby’s overall health and bilirubin levels.

Newborns often have mild jaundice, and a bilirubin level of 10.4 mg/dL at 6 days old isn’t uncommon. Since the direct bilirubin is only 0.5 mg/dL, it’s generally not a major concern. Just keep monitoring and follow up with your pediatrician to ensure levels normalize.

28 days newborn TSB how many
Myhealth Team
Sep 30, 2024 at 8:38 AM.
For a 28-day-old newborn, total serum bilirubin (TSB) levels are typically considered normal if they are below 12-15 mg/dL for breastfed babies and 10-12 mg/dL for formula-fed infants. Levels higher than these thresholds could indicate jaundice and might require further evaluation and monitoring.
If you have specific concerns or if the bilirubin levels are elevated, it's always best to consult with a pediatrician for personalized guidance and care.

A total bilirubin level of 13.8 mg/dL in a 90-hour-old newborn is elevated but not immediately dangerous. Close monitoring is essential, as levels can increase. Your pediatrician may recommend phototherapy if necessary. Ensure your baby is feeding well, as this can help lower bilirubin. Consult your doctor for personalized advice.

It sounds like your baby experienced neonatal jaundice, which is common in newborns due to the breakdown of red blood cells and the liver's immaturity in processing bilirubin. It's positive that the bilirubin levels decreased after the blood transfusion. However, the subsequent increase in bilirubin is concerning and warrants further evaluation by a healthcare provider. There could be various reasons for the fluctuation in bilirubin levels, such as an underlying medical condition, breastfeeding issues, or ineffective treatment. It's crucial to consult with a pediatrician or neonatologist for a comprehensive assessment. They may recommend additional tests, treatment adjustments, or monitoring to ensure your baby's health and manage the jaundice effectively.

How can we detect Jaundice after 7 days when we are at home. Any symptoms
Myhealth Team
Jun 7, 2023 at 8:17 AM.
Hi Chaitu, Thankyou for your comment. Jaundice can be detected at home by observing certain symptoms. Look for yellowing of the skin and eyes, dark urine, pale stools, fatigue, and loss of appetite. If you notice these signs, it's important to consult a healthcare professional for proper evaluation and diagnosis.
