ResumoABSTRACT. Human o‐lactalbumin (α‐LA) has been used as a marker for measuring macromolecular absorption. The serum concentration of human α‐LA after a human milk feed has been studied in 32 healthy very low birthweight infants (VLBW), fed human milk (gestational age 26–32 weeks) and in 56 term, breast‐fed infants, age 3–140 days. At 31 weeks of gestation the serum concentration of human α‐LA was more than 10 times higher (mean value 3000 and median value 2101 μg/1 serum/1 human milk/kg body weight, n = 11) than in the term infants aged 3–30 days (mean value 257 and median value 152, n = 29). The serum concentration of o‐LA decreased with increasing maturity in the VLBW‐infants. At a postconceptional age of 37 weeks the values were similar (mean value 200 and median value 99, n = 8) to those found for term infants during the first month. In the term infants a decreasing absorption of α‐LA was found with increasing postnatal age.
