There are two main values of jaundice conversion control table, one is 1mg/dl = 17.1umol/L and 390umol/L = 22.8mg/dl. Physiological jaundice, jaundice appears 2-5 days after birth and is generally in good condition, resolves within 14 days in full-term infants and 3-4 weeks in preterm infants. Serum bilirubin level is <205umol/L, i.e. 12mg/dl in term infants and <257umol/L, i.e. 15mg/dl in preterm infants. pathological jaundice, appears too early, serum bilirubin appears within 24 hours of birth, >205umol/L, i.e. 12mg/dl in term infants and >257umol/L, i.e. 15mg/dl in preterm infants. /dl, jaundice lasting too long, full-term infants > 2 weeks, preterm infants > 4 weeks, jaundice receding and reappearing, serum conjugated bilirubin > 25umol/L or 1.5mg/dl, if consistent with pathological jaundice, it is best to go to the hospital for medical treatment.
