Introduction
Newborns are generally tested for jaundice 2 to 3 days after birth. Jaundice is common in newborns and typically appears within 2 to 3 days after birth, mostly representing physiological jaundice. It is recommended to visit a hospital 2 to 3 days after birth to measure the bilirubin level and, under medical guidance, determine whether the jaundice is physiological or pathological.

Jaundice in newborns is generally tested 2 to 3 days after birth.
Newborns are prone to developing jaundice, which typically appears within 2 to 3 days after birth and is mostly physiological. It is recommended to visit a hospital 2 to 3 days after birth to measure bilirubin levels and, under medical guidance, determine whether the jaundice is physiological or pathological. Physiological jaundice usually peaks around days 4 to 6 and then gradually decreases; the jaundice typically resolves completely within about one week and generally does not require treatment. However, if bilirubin levels are very high, if jaundice persists for a prolonged period, or if it worsens progressively, it may indicate pathological jaundice. In such cases, prompt medical evaluation is advised, and treatment for jaundice should be administered under a doctor's supervision.
For newborns with jaundice, regular exposure to sunlight (ultraviolet light) is recommended, as it can help reduce jaundice. For those with pathological jaundice, monitoring changes in jaundice regularly and understanding the condition can aid in effective treatment.
