Jaundice of 8.5 is normal for most people, but is high in newborns just one day old. The range of jaundice can be detected by instruments as well as blood tests. Adults are tested for jaundice, usually by blood draw. The reference range for total bilirubin concentration is 1.7-21mg/dL, so 8.5mg/dL is not high and is normal. Newborns due to the inconvenience of blood sampling, jaundice through the instrument to measure the frontal, facial jaundice index to determine jaundice, normal jaundice in normal full-term newborns normal value is not more than 12.9mg/dL, so the total bilirubin of 8.5mg/dL belongs to the normal. However, the total bilirubin of the first day of life of newborns does not exceed 7mg/dL, if it is 8.5mg/dL is considered abnormal, need to pay close attention to monitor the range of total bilirubin, and subsequently, if it continues to rise, it needs to be treated. Jaundice of 8.5 in adults is normal and does not require treatment; if jaundice of 8.5 in newborns it is recommended that prompt medical attention be sought.
