Relation of reticulocytosis to positive Coombs tests in NZB and other mice.
S EVERAL RECENT REPORTS have incriminated reticulocytes as the cause of “false positive” Coombs tests obtained in spontaneous or experimentally induced anemia.14 As reticulocytosis is frequently associated with the spontaneous Coombs positive hemolytic anemia which develops in NZB mice, and because the positive Coombs test has been used by Holmes and Burnet5T as the main basis for calling the c...
متن کاملABO 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 ...

متن کاملABO Hemolytic Disease Leading to Hyperbilirubinemia in Term Newborns: Value of Immunohematological Tests
Materials and Methods: This two-year retrospective study of 1800 jaundiced term-neonates studied 355 cases due to ABO incompatibility divided into two groups: with and without hemolytic disease. Relation of laboratory parameters and immunohematological tests to severity of disease were studied. We did not analyze the maternal antibody titer or elusion test, and this was a limitation of the stud...
متن کاملPathology consultation on drug-induced hemolytic anemia.
Drug-induced immune hemolytic anemia is considered to be rare but is likely underrecognized. The consulting pathologist plays a critical role in integrating serologic findings with the clinical history, as drug-induced antibodies should be distinguished as either drug-dependent or drug-independent for appropriate clinical management. Drug-dependent antibodies (DDABs) are most commonly associate...
