What is dangerous bilirubin level in newborns?
The point at which a bilirubin level is dangerous changes with a baby’s age. A level of 7 m/dL at 5 hours old is very concerning, but a level of 16 m/dL may be fine for a baby who is 4 days old. If a baby’s bilirubin level is high, then blood tests are performed. 6
How does phototherapy treat jaundice?
– Phototherapy works through the process of photo-oxidation. – Photo-oxidation adds oxygen to bilirubin, making it easier to dissolve in water. – The liver can then easily break down the oxygen-bound bilirubin and remove them from the blood. – Once bilirubin is removed, it can easily pass through the urine.
