How to Diagnose Newborn Jaundice?

Question

How can newborn jaundice be detected?

Answer

The diagnosis of newborn jaundice primarily involves the following three methods:

1. Visual observation of the yellowing of the skin, mucous membranes, and sclera.
2. Skin measurement of bilirubin levels (TcB), a non-invasive method.
3. Blood testing for serum bilirubin levels (TBIL), which is the gold standard for diagnosing jaundice. The disappearance of jaundice does not mean a complete resolution but indicates that bilirubin levels have dropped to a safe range. If bilirubin levels exceed the normal standard, treatment is required. Treatment methods mainly include phototherapy, exchange transfusion, and medication. Exchange transfusion is typically used for moderate to severe jaundice where phototherapy is ineffective. Medication treatment is slower and is commonly used for newborns over 2 weeks old.
