Evidence has been presented to show that:
1. The average vitamin E level in plasma or serum at birth is .23 mg./100 cc. with wide variations in both term and premature infants regardless of birth weight.
2. The average level of vitamin E in cord blood is equal to the average level of the infant's blood taken within the first 24 hours, although in any one case they may vary as much as 50% to 75%.
3. The vitamin E level in term infants appears to be higher after five days, averaging .36 mg./100 cc.
4. The vitamin E level in premature infants does not increase for two months. Between three and six months of age it increased to an average of .50 mg./100 cc.
