Jaundice Newborn Diagnosis and Evaluation
How Is Newborn Jaundice Evaluated and Monitored at Liv Hospital?
The diagnostic process for jaundice in newborns is a critical safety net in neonatal care. Because bilirubin levels can change rapidly in the first 100 hours of life, the evaluation must be both precise and frequent. The goal of diagnosis is threefold: to determine the exact concentration of bilirubin in the blood, to track the rate at which that level is rising, and to identify the underlying cause of the jaundice.
At Liv Hospital, every newborn undergoes a standardized bilirubin screening protocol before discharge. We utilize a combination of clinical visual assessments, non-invasive technology, and precise laboratory analysis to ensure that no baby is at risk for complications.
Visual Clinical Assessment (The Kramer Scale)
Before any machines are used, clinicians perform a visual check. Jaundice usually progresses from the head downward. Doctors use the Kramer Scale to estimate the bilirubin level based on how far down the body the yellowing has reached.
While helpful, visual assessment alone is not sufficient for a definitive diagnosis, especially in infants with darker skin tones or those under artificial lights.
Transcutaneous Bilirubinometry (TcB)
This is a modern, non-invasive screening tool. A device called a bilimeter is placed gently against the baby’s forehead or chest. It uses light waves to measure the intensity of the yellow pigment in the skin tissue.
Total Serum Bilirubin (TSB) Test
The TSB is the “gold standard” for diagnosis. A small amount of blood is taken via a heel prick to measure the exact amount of bilirubin in the plasma.
The Nomogram Analysis (Hour-Specific Risk)
A bilirubin level of 10 mg/dL might be normal for a 3-day-old baby but dangerously high for a 12-hour-old baby.
Blood Type and Rh Factor Screening
If a baby develops jaundice within the first 24 hours, doctors immediately check the blood types of both mother and baby.
Direct Antiglobulin Test (Coombs Test)
This specific blood test checks if the baby’s red blood cells have been coated with maternal antibodies.
A “Positive Coombs” test indicates that the red blood cells are being targeted for destruction, which explains a rapid rise in bilirubin.
Complete Blood Count (CBC) and Reticulocyte Count
Peripheral Blood Smear
A laboratory technician looks at the baby’s blood cells under a microscope. This can identify abnormally shaped cells (like in Spherocytosis) that break down more easily than healthy cells, leading to Jaundice Newborn.
G6PD Enzyme Screening
In some ethnic groups, a deficiency of the G6PD enzyme is common.
This enzyme protects red blood cells; without it, the cells can rupture easily when the baby is stressed by certain triggers, leading to a sudden and severe spike in bilirubin.
Liver Function and Bile Duct Evaluation
If the “Direct” (conjugated) bilirubin is high, the focus shifts to the liver and gallbladder.
How Does Liv Hospital Ensure Accurate Diagnosis of Newborn Jaundice?
At Liv Hospital, diagnostic precision is central to neonatal safety. Our NICU and nursery use advanced transcutaneous bilirubinometers for non-invasive monitoring.
When blood testing is needed, rapid laboratory results allow immediate treatment decisions.
Following American Academy of Pediatrics guidelines, every newborn jaundice case is assessed with the highest clinical standards.

Bilirubin levels can rise or rebound quickly. Regular testing ensures they do not reach levels that could harm the brain.
There is no single normal value. It depends on the baby’s age in hours and whether they are premature.
It is a reliable screening tool, but if levels approach the treatment threshold, a blood test is required for accuracy.
Yes. Premature infants have less mature livers and are treated at lower bilirubin levels.
Not always. Risk increases if there was blood type incompatibility or a genetic condition like G6PD deficiency.
