Self-measurement of neonatal jaundice is not recommended. For suspected neonatal jaundice, it is recommended to go to the hospital for laboratory tests and other definitive diagnosis in order to avoid delaying the condition. Neonatal jaundice can be seen in transient elevation of bilirubin level at birth, hemolysis, diseases, infections, etc., and may present with symptoms such as yellowing of the skin and sclera, anorexia, and unexplained crying and irritability, etc. The manifestation of the above mentioned symptoms varies from one newborn to another, and self-assessment may result in omission of diagnosis and misdiagnosis, so self-assessment is not recommended. The diagnosis of neonatal jaundice mainly relies on measures such as serum bilirubin, liver function and fecal examination. If the diagnosis of neonatal jaundice is confirmed, depending on the type of neonatal jaundice and the degree of the disease, targeted treatment should be carried out according to the doctor’s instructions, including treatment by light therapy and plasma exchange. If you suspect neonatal jaundice, it is recommended that you visit a hospital promptly to avoid delaying treatment.
