Newborn Jaundice Testing: Diagnosis & Care
Understanding Newborn Jaundice
Newborn Jaundice Testing: Diagnosis & Care Jaundice in newborns makes their skin and eyes look yellow. This happens when there’s too much bilirubin, a substance made when old red blood cells break down. About 60% of full-term babies and 80% of preterm babies get jaundice. It’s important to catch it early to help them.
What is Newborn Jaundice?
Newborn jaundice makes an infant’s skin and the white part of their eyes look yellow. This is because they have too much bilirubin. Babies are born with livers that can’t handle bilirubin well yet. So, they need tests to check for bilirubin levels early.

ACIBADEM Health Point: The Future of Healthcare
We believe that everyone deserves access to quality healthcare, which is why we have established multiple branches in strategic locations. Whether you're in need of routine check-ups, specialized treatments, or emergency care, ACIBADEM Health Point is here for you.Causes of Jaundice in Newborns
There are a few reasons why newborns get jaundice:
- Physiological Jaundice: This is the most common type. It happens because newborns have livers that are still getting used to working right.
- Premature Birth: Babies born too soon often get jaundice because their livers aren’t fully developed yet.
- Hemolysis: When red blood cells break down too fast, bilirubin levels go up. This means babies need tests to check their bilirubin levels.
- Infection: Some infections can make bilirubin levels go up. Catching jaundice early is key to stopping it from getting worse.
- Genetic Disorders: Some babies are born with genes that make it hard for their livers to process bilirubin. This can mean they stay jaundiced for a longer time.
Knowing what causes jaundice helps doctors catch it early and treat it. This keeps babies healthier.
Cause | Description | Impact |
---|---|---|
Physiological Jaundice | Common and normal increase in bilirubin | Usually resolves without treatment |
Premature Birth | Immature liver | Higher risk of jaundice |
Hemolysis | Rapid red blood cell breakdown | High bilirubin levels |
Infection | Elevates bilirubin | Requires medical attention |
Genetic Disorders | Inherited conditions affecting bilirubin | Prolonged jaundice |
Signs and Symptoms of Jaundice in Infants
It’s very important to spot jaundice in babies early. Look for signs that are easy to see or notice in their behavior. This helps in treating jaundice quickly.

Babies with jaundice often look yellow. This yellow color shows up on their skin and in their eyes first. It moves down their body over time.
Doctors check for this yellow color when they check for jaundice. They use it to see how bad it is.
Behavioral Changes
Jaundice can also change how babies act. They might not want to eat as much. They could sleep a lot and be hard to wake up.
They might also seem very limp or floppy. These are signs that they might have jaundice. It means they need to see a doctor.
Importance of Testing for Jaundice in Newborns
Testing for jaundice in newborns is very important. It helps catch jaundice early. This is key to stop serious problems like kernicterus, which can harm the brain for life.
Also, newborn jaundice screening finds other health problems. These problems can be serious and need quick action. So, checking often helps keep newborns safe and healthy.
Methods of Newborn Jaundice Screening
It’s very important to check for jaundice in newborns early. We use two main ways to do this: looking at the baby and testing bilirubin levels. These help us find and treat jaundice in babies.
Visual Inspection
Healthcare workers look at the baby’s skin and eyes for yellow color. This is a sign of jaundice. They do this under natural light to be sure.
Even though looking is helpful, it’s not as good as lab tests.
Bilirubin Level Testing
Testing bilirubin levels in babies is a better way to find jaundice. There are two tests: Transcutaneous Bilirubinometry (TcB) and Total Serum Bilirubin (TSB).
Testing Method | Description | Accuracy |
---|---|---|
Transcutaneous Bilirubinometry (TcB) | Non-invasive method using a device to measure bilirubin levels through the skin. | Moderately Accurate |
Total Serum Bilirubin (TSB) | A blood test that measures the exact level of bilirubin in the bloodstream. | Highly Accurate |
Using both methods helps us check for jaundice in babies well. This means we can help them get the right care fast.
How Bilirubin Testing in Newborns is Conducted
Bilirubin testing in newborns is key to spot and treat neonatal jaundice. It uses two main tests: a skin test and blood analysis. Newborn Jaundice Testing: Diagnosis & Care
Transcutaneous Bilirubinometer
A transcutaneous bilirubinometer is a device that checks bilirubin levels through the skin. It looks at the skin’s color to figure out bilirubin levels. This test is quick, easy, and gives fast results. It helps decide if more tests are needed. Newborn Jaundice Testing: Diagnosis & Care
Blood Sample Analysis
For accurate bilirubin levels, blood tests are done. A tiny blood sample is taken from the baby’s heel. This method is more detailed but takes longer and is a bit more painful. Newborn Jaundice Testing: Diagnosis & Care
Method | Type | Pros | Cons |
---|---|---|---|
Transcutaneous Bilirubinometer | Non-invasive | Quick, painless, immediate results | Less precise |
Blood Sample Analysis | Invasive | Highly accurate, detailed results | Painful, longer processing time |
Interpreting Results of Newborn Jaundice Evaluation
When checking for newborn jaundice, doctors look at many things. They consider the baby’s age, risk factors, and bilirubin levels. They use charts to see if the jaundice is normal or if the baby needs help. Newborn Jaundice Testing: Diagnosis & Care
Doctors compare the baby’s bilirubin levels to charts based on the baby’s age. These charts show how serious the jaundice is and if it’s getting worse: Newborn Jaundice Testing: Diagnosis & Care
Age of Infant (in hours) | Normal Bilirubin Range (mg/dL) | Intervention Threshold (mg/dL) |
---|---|---|
0-24 | 2-6 | 15 |
25-48 | 4-8 | 18 |
49-72 | 6-10 | 20 |
More than 72 | 8-12 | 25 |
Doctors also think about risk factors like being born too early. Babies at risk might need more checks and help sooner. By looking at all these things, doctors can make the best plan for the baby’s health. Newborn Jaundice Testing: Diagnosis & Care
Risk Factors for Developing Jaundice in Newborns
Knowing the risk factors of newborn jaundice helps with early detection and treatment. Some things make a baby more likely to get jaundice. Spotting these early can help catch jaundice in babies quickly.
Prematurity
Premature babies face a big risk of jaundice. Their livers aren’t fully grown, so they can’t handle bilirubin well. This means they might have more bilirubin in their blood, making jaundice more likely.
Blood Type Incompatibility
Blood type issues are also a big concern. If the baby’s blood type doesn’t match the mom’s, the baby’s immune system might attack its own red blood cells. This makes more bilirubin, so it’s important to watch for jaundice closely.
Treatment Options for Jaundice in Newborns
Jaundice is common in newborns and can be treated. Parents and caregivers need to know how to treat it. This helps keep the baby healthy.
Phototherapy
Phototherapy is the top way to treat newborn jaundice. It uses special light to break down bilirubin in the baby’s skin. This helps get rid of bilirubin from the body.
The baby lies under the light, wearing only a diaper. Their eyes are covered to keep them safe. Phototherapy works well and can help in just a few days.
Exchange Transfusion
If phototherapy doesn’t work, an exchange transfusion might be needed. This is for babies with very high bilirubin levels. It replaces the baby’s blood with donor blood to lower bilirubin fast.
This method is more serious but very important. It keeps the baby safe and stops serious problems from high bilirubin.
Home Care Tips
At home, make sure the baby stays hydrated and well-fed. Feeding often helps move bilirubin out of the body. Watch the baby’s skin color and how they act.
Talk often with doctors to make sure the jaundice is being treated right.
Monitoring and Follow-Up Care
Keeping an eye on newborn jaundice after leaving the hospital is key. After starting treatment, it’s important to watch bilirubin levels closely. Doctors suggest regular check-ups to see how the baby is doing and catch any new jaundice signs early.
For babies sent home early, watching for jaundice is extra important. These babies might get very sick from jaundice because bilirubin levels can go up later. If this happens, they might need to go back to the hospital or see their doctor again for tests.
Parents should watch their babies closely and ask for help if things get worse or if they see new signs. Steps like phototherapy or even blood transfusions might be needed. Keeping a close eye on the baby makes sure they get the right care fast. This helps parents feel secure and makes sure the baby gets the best care for jaundice.
