Thanks for placing your query here.
I can appreciate your concerns.
Light treatment threshold depends upon several factors;
1/-Was the baby born premature or full term ?
2/-How many days old ,since birth ?
3/-Is the baby of average weight?
4/-blood groups of mother & baby?
5/-Is direct coomb test positive ?
In general if the baby is otherwise well & over 1 week old, light therapy
is needed at or beyond
Hope I have answered your query.
If you have any further questions I will be happy to help.
Wish your baby a good health.
