title: [Neonatal jaundice due to anti-D allo-immunization with negative direct Coombs' test].
abstract: The case is reported of a newborn with jaundice due to anti-D Rh iso-immunization, with a negative Coombs' test. The finding of a positive red cell auto-agglutination test, the red cells being treated with bromelin and incubated in their own serum, suggests an immune phenomenon. Free antibody with anti-D specificity reacting with bromelin treated R.B.C.'s was found in the sera of the mother and infant.
