DD is 2 days old. Has no visible symptoms of jaundice, at the hospital this morning they did a standard screening which came up high enough to warrant the need to blood test & check Bilirubin levels as he may need phototherapy. I'm so confused how he has no symptoms yet requires the blood test indicating he's a scoring quite high on the screening they do? I'm emotional as my first was in ICU & appreciate it's not the same thing but it's still going back in to hospital if it's needed.
