Fetal Cell Stain, Kleihauer-Betke Stain, KB stain, Acid Elution Stain
Used to quantify the size of a fetal-maternal hemorrhage after a positive Fetal Maternal Hemorrhage Screen (FMH) and to determine appropriate Rh Immunoglobulin dosage. This test can also be used to detect and quantify a fetal-maternal hemorrhage at any point in pregnancy regardless of the blood type of the patient and whether or not the blood type of the fetus or infant is known.
