Normal Values for Neonatal Jaundice (Baby Jaundice)

Neonatal jaundice is a common condition that affects newborns. It is caused by a buildup of bilirubin, a yellow pigment that is produced when red blood cells break down. Normal values for neonatal jaundice vary depending on the age of the baby and the method used to measure bilirubin levels.

Measuring Bilirubin Levels

Bilirubin levels can be measured in two ways:

Transcutaneous bilirubin (TcB): This is a non-invasive test that measures bilirubin levels through the skin using a light probe.

Total serum bilirubin (TSB): This is a blood test that measures the total amount of bilirubin in the blood.

Normal TcB Values

Normal TcB values for newborns vary depending on their age:

Birth to 24 hours: Less than 2 mg/dL

24-48 hours: Less than 5 mg/dL

48-72 hours: Less than 8 mg/dL

3-4 days: Less than 10 mg/dL

5-7 days: Less than 8 mg/dL

Normal TSB Values

Normal TSB values for newborns also vary depending on their age:

Birth to 24 hours: Less than 5 mg/dL

24-72 hours: Less than 13 mg/dL

3-5 days: Less than 17 mg/dL

6-7 days: Less than 15 mg/dL

When to Be Concerned

Bilirubin levels that are higher than normal may indicate an underlying medical condition, such as:

Physiological jaundice: This is the most common type of jaundice in newborns and is caused by the normal breakdown of red blood cells. It typically resolves within 1-2 weeks.

Breast milk jaundice: This type of jaundice is caused by substances in breast milk that can inhibit the liver's ability to remove bilirubin. It usually develops within 2-3 weeks of starting breastfeeding and can last for several months.

Liver disease: Jaundice that develops in the first 24 hours of life or persists for more than 2 weeks may indicate liver disease.

Hemolytic disease: This is a condition in which the baby's red blood cells are destroyed by the mother's antibodies. It can cause severe jaundice and other complications.

Treatment for Neonatal Jaundice

Most cases of neonatal jaundice do not require treatment. However, if bilirubin levels become too high, treatment may be necessary to prevent complications such as kernicterus, a serious condition that can cause brain damage.

Treatment options for neonatal jaundice include:

Phototherapy: This involves exposing the baby to a special light that helps break down bilirubin.

Exchange transfusion: In severe cases, an exchange transfusion may be necessary to replace the baby's blood with blood from a donor.

Prevention of Neonatal Jaundice

There is no sure way to prevent neonatal jaundice, but some measures may help reduce the risk, such as:

Early and frequent breastfeeding: Breastfeeding helps stimulate the baby's liver and remove bilirubin from the body.

Avoiding dehydration: Dehydration can increase bilirubin levels. Make sure your baby is getting enough fluids, especially if they are breastfed.

Monitoring bilirubin levels: If your baby has risk factors for jaundice, your doctor may recommend regular bilirubin testing.
