Hour-Specific Bilirubin Nomogram in Infants With ABO Incompatibility and Direct Coombs-Positive Results

Hour-specific bilirubin nomogram in infants with ABO incompatibility and direct Coombs-positive results.

OBJECTIVE To determine the usefulness of the hour-specific Bhutani et al bilirubin nomogram when applied to infants with Coombs-positive test results. DESIGN Retrospective chart review. SETTING Term nursery and neonatal intensive care unit of a university-affiliated hospital. PATIENTS All infants with A+ or B+ blood type born in our center from September 1, 2006, through August 31, 2008, ...

Correlation of cord bilirubin levels with hyperbilirubinaemia in ABO incompatibility.

We studied 91 offspring of ABO incompatible preganacies and 30 controls resulting from O--O pregnancies to test whether cord bilirubin levels could be used to predict the severity of hyperbilirubinaemia in ABO incompatibility. Blood group, direct Coombs's test, and serum bilirubin estimations were carried out on cord blood, and bilirubin estimations at 12, 24, 36, and 48 hours of life.

ABO Hemolytic Disease Leading to Hyperbilirubinemia in Term Newborns: Value of Immunohematological Tests

Introduction ABO hemolytic disease of the newborn is most common cause of neonatal jaundice; previous studies have shown a poor correlation between serologic tests and clinical course in affected infants. The aim of this study was to identify the value of direct and indirect Coombs’ immunohematological tests, to identify the incidence of hemolytic disease in newborns (ABO-HDN). Methods : This  ...

Positive direct Coombs test induced by phenylhydrazine.

Anemia with positive direct Coombs' test induced by trypan blue.

as evidence of autoimmune phenomena. The experimental production of positive antiglobulin tests by drugs and chemical agents, however, has suggested that nonimmunologic mechanisms may also be responsible for protein coating of erythrocytes.2’3 During attempts to produce tumors of the reticuloendothelial system in rats by injection of trypan blue, an anemia, chacacterized by increased ervthrocyt...
