In Reply : α-Fetoprotein Normal Values

We would like to thank Caglar et al for providing further information about normal values of α-fetoprotein in neonates and infants. Although the number of serum α-fetoprotein values in the premature neonate is still limited, the table referred to by them further illustrates that normal values in neonates and infants are different from adult normals. The values vary with both gestational age and postnatal age of the infants. Physicians who interpret α-fetoprotein values in neonates and infants need to keep this information in mind.
