Description

The Kleihauer-Betke (KB) test, Kleihauer-Betke (KB) stain or Kleihauer test, is a blood test used to measure the amount of fetal hemoglobin transferred from a fetus to an Rh-negative mother 's bloodstream. The results of the test are used to determine the required dose of Rh immune globulin (RhIg) to inhibit formation of Rh antibodies in the mother and prevent Rh disease in future Rh-positive children. In this test, hemoglobin is eluted from the mother's red blood cells, whereas the fetal hemoglobin is resistant to this acid elution. When the slides are stained, the maternal cells appear very pale, whereas fetal cells are stained and appear bright pink. Simple comparative counts allow an estimate of whether a significant fetal-maternal hemorrhage occurred. In those with positive tests (25% or more of estimated fetal blood volume lost), follow up testing (at a postpartum check) should be done to rule the possibility of a false positive.
