Newborn Jaundice Monitor
Select your baby's birth time to start monitoring jaundice levels
What is Transcutaneous Bilirubin (TcB)?
TcB is a non-invasive method of measuring bilirubin levels through the skin, primarily used for rapid screening of newborn jaundice.
Why monitor jaundice?
Newborn jaundice is common, but severe hyperbilirubinemia can cause neurotoxicity. Timely monitoring helps with early detection and treatment.

What is newborn jaundice?
Newborn jaundice is a common condition in newborns caused by elevated bilirubin levels in the blood, which makes the skin and whites of the eyes appear yellow. Most newborns develop jaundice 2-3 days after birth, and it typically resolves naturally within 1-2 weeks.
What does TcB mean?
TcB stands for Transcutaneous Bilirubin, which is a non-invasive method of measuring bilirubin levels through the skin. Compared to blood tests, TcB measurement is faster, painless, and suitable for initial screening of newborn jaundice.
When does newborn jaundice need treatment?
Treatment for newborn jaundice depends on the baby's age, bilirubin levels, and risk factors. Generally, when bilirubin levels exceed the phototherapy threshold for the corresponding age, phototherapy treatment should be considered. Treatment decisions should always be made by healthcare professionals based on clinical assessment.
How to monitor newborn jaundice?
Monitor newborn jaundice by observing changes in your baby's skin color, regularly measuring TcB values, or checking serum bilirubin levels. Observe in natural light, paying special attention to the face, chest, and abdomen. If jaundice worsens rapidly or persists too long, seek medical attention promptly.
What are normal bilirubin levels for a 1-day-old baby?
For a 1-day-old baby (24 hours of life), TcB values should ideally be within the safe range. Specific normal values depend on the baby's individual circumstances and measurement timing. Professional hour-of-life bilirubin nomograms should be used for accurate assessment.
How long does it take for jaundice to resolve?
Physiological jaundice in full-term newborns typically appears 2-3 days after birth, peaks on days 4-6, then gradually decreases, with most cases resolving completely within 2 weeks. Premature infants may have jaundice lasting longer, up to 3-4 weeks.
What is pathological jaundice?
Pathological jaundice occurs when jaundice appears too early (within 24 hours of birth), is too severe (exceeding normal ranges for age), lasts too long (over 2 weeks in full-term babies, over 3-4 weeks in premature babies), or reappears after resolution. This requires immediate medical attention.
What are the risks of newborn jaundice?
Mild physiological jaundice is harmless to babies, but severe hyperbilirubinemia can cause bilirubin encephalopathy, affecting neurological development. Therefore, timely monitoring and appropriate treatment are crucial.
Is phototherapy safe for treating newborn jaundice?
Phototherapy is the standard treatment for newborn jaundice and has been proven safe and effective through decades of clinical use. Phototherapy uses specific wavelengths of light to help convert bilirubin into water-soluble substances, thereby reducing bilirubin levels in the blood.
How to prevent newborn jaundice?
While physiological jaundice cannot be completely prevented, risks can be reduced by: 1) Starting breastfeeding early, 2) Ensuring adequate feeding frequency, 3) Regular prenatal care, 4) Avoiding prolonged labor. Most importantly, regular monitoring and timely medical consultation are essential.
When should I seek immediate medical attention?
Seek immediate medical attention if: 1) Jaundice appears within 24 hours of birth, 2) Jaundice worsens rapidly, 3) Baby shows lethargy, poor feeding, or fever, 4) TcB values exceed the danger threshold on monitoring charts, 5) Jaundice persists beyond expected duration.
What is the difference between TcB and TSB?
TcB (Transcutaneous Bilirubin) is a non-invasive screening method measured through the skin, while TSB (Total Serum Bilirubin) is an accurate method measured through blood testing. TcB is primarily used for screening, and when TcB values are elevated, further TSB testing is needed to determine accurate bilirubin levels and guide treatment.
This tool is for educational and reference purposes only and cannot replace professional medical advice, diagnosis, or treatment. Transcutaneous bilirubin (TcB) measurement is only a rapid screening tool, and clinical decisions should be based on serum bilirubin (TSB) levels. If you have any medical questions or concerns, please consult a qualified healthcare professional. In case of emergency, please contact your doctor or emergency department immediately.
