Question
A three-and-a-half-month-old girl baby developed jaundice two days after birth and was found to have an elevated bilirubin index after testing. At two months old, she underwent a skin test, with three values measured at two 4-point-something and one 3-point-something. The doctor said it was basically normal, slightly elevated, but did not explicitly state the normal value range. What should be the normal value for neonatal jaundice skin tests?
Answer
The normal value for neonatal jaundice skin tests is typically less than 10, but specific values may vary slightly depending on the instrument used. For blood tests, the normal bilirubin level in the blood should generally be less than 205umol/l (12mg/dl). For a healthy baby of 30 days, the normal total bilirubin range is 1.7～17.1umol/l (0.1～1.0mg/dl), with direct bilirubin ranging from 0～6.8umol/l (0～0
