[Concentrations of IgM and IgA in the umbilical cord blood of 400 newborn infants: possible significance and correlations with prenatal infections (preliminary note)].
IgM and IgA dosed in cord sera of 400 infants. IgM are present in all samples; 16.25% of them show levels 25 mg/100 cm3. IgA are present in 5.75%, but only 2.25% show levels 6 mg/100 cm3. Our controls have confirmed they depend on maternal blood contamination. Correlations between IgM and IgA levels and perinatal infections are considered. Further studies are required to determine the presumptive nature of infectious agents.
