ABO Group Test (Blood Typing)
The ABO Group test determines a person's ABO blood type and Rh factor from a blood sample. Quest describes this information as used in identifying candidates for Rh immune globulin and in assessing the risk of hemolytic disease of the newborn.
About this test
Blood typing sorts a sample by ABO group and Rh factor, the two classifications Quest lists as relevant to transfusion and pregnancy-related decisions. Quest analyzes a 5 mL whole blood sample, collected in an EDTA (pink-top) tube, using immune agglutination methodology to determine both results.
The test reports a single result: ABO group and Rh status. Quest describes this information as relevant to identifying who may be a candidate for Rh immune globulin and to assessing the risk of hemolytic disease of the newborn, both of which a clinician interprets in the context of a person's pregnancy or transfusion history.
