Vitamin E serum levels in newborn infants undergoing phototherapy.

The serum vitamin E levels of 11 full-term and 10 premature infants, jaundiced and subjected to phototherapy, were measured and compared wth 9 premature and 10 full-term jaundiced control infants. No differences were observed before or after phototherapy or 1 week after stopping it. The same negative results were noted in the two groups of infants regarding the values of microhematocrit, Hb and reticulocytes.
