title: A further investigation of the relationship between serum diamine oxidase (DAO) and gestational age.
abstract: A standard error of one to two weeks must be accepted if the duration of pregnancy is calculated from serum diamine oxidase (DAO) concentrations. After the 16th week of pregnancy, the enzyme concentration is too variable to be used for calculations of gestational age.
