The iron is conserved for reuse, whereas carbon monoxide is excreted through the lungs and can be measured in the patient's breath to quantify bilirubin production. Neonatal physiologic jaundice results from the accelerated destruction of fetal erythrocytes, the excessive production of bilirubin from this process, and the low hepatic excretory capacity due to the low concentrations of ligandin.

Tin-mesoporphyrin inhibits heme oxygenase However, some deconjugation occurs in the proximal small intestine through the action of B-glucuronidases located in the brush border. The liver normally absorbs and processes bilirubin, but in the newborn there are not enough enzymes present yet for the liver to absorb and metabolize the bilirubin. Hemolytic anemia does not increase entry into, nor alter rate of clearance of bilirubin from rat brain. Neonatal Jaundice first becomes visible in the face and forehead.
