My baby is 7 weeks old and still having jaundice 110. The Doctor at the polyclinic referred us back to KK to do a liver blood test. Should I be worried?

Nope. It's actually not an uncommon thing. My son was asked to go and test for jaundice every 2-3 days and subsequent for liver every week. It pained my heart to see him cry everytime he was pricked. But after a while, I stopped going back to KKH for the liver test as it's just to check the enzyme level. He's peeing and pooping fine, so I didn't see what's the reason to draw his blood so often. I only scheduled his blood test after 3 weeks and his results were good enough to be discharged :)
