Yes the levels are fine. U may keep monitoring for bilirubin via a transcutaneous machine, if u ever think that jaundice is increasing. At 45 days sometimes due to breast milk , this can happen. But it is not a big concern at all. I still don’t know why u had done the test, but it’s in normal range, assuming the baby was full term and feeding well, passing urine adequately

It's normal

This is normal for age. But always have a follow up with your pediatrician to see the rising levels and look for normal light yellow coloured urine and yellow green poop. Anytime decreased feeding with increasing yellowish discoloration of eyes/skin should alert you.
