Specific Aim 1: To determine total serum bilirubin (TSB) and unbound bilirubin (Bf) levels in term and late preterm infants during the first week of life. Specific Aim 2: Measure Bf levels in breast fed and formula fed infants and examine their relationship to unbound fatty acid (FFAu) levels. Specific Aim 3: To demonstrate that phototherapy results in different changes in TSB and Bf.
