Jaundice management may involve treating infectious causes and stopping medication that could be contributing. Among newborns, depending on age and prematurity, a bilirubin greater than 4–21 mg/dL (68-360 µmol/L) may be treated with phototherapy or exchanged transfusion. The itchiness may be helped by draining the gallbladder or ursodeoxycholic acid. The word "jaundice" is from the French "jaunisse", meaning "yellow disease". The main sign of jaundice is a yellowish discoloration of the white area of the eye and the skin. Urine is dark in colour. Slight increases in serum bilirubin are best detected by examining the sclerae, which have a particular affinity
Neonatal jaundice peaking in the sixth to 14th days of life. This late-onset jaundice may develop in up to one third of healthy breastfed infants. Most infants develop visible jaundice due to elevation of unconjugated bilirubin concentration during their first week. This is called physiological jaundice. This pattern of hyperbilirubinemia has been classified into two functionally distinct periods. Mechanism involved in physiological jaundice are mainly: Diagnosis is often by measuring the serum bilirubin level in the blood. In those who are born after 35 weeks and are more than a day old transcutaneous bilirubinometer may also be used. The use of an
