Abstract
Two procedures for the detection of fetal erythrocytes are described. The first is a screening technic which allows distinction between small and large fetal– maternal hemorrhages. Most cases will have small fetal– maternal hemorrhages and will be protected by the standard dose of 300 μ g. Rh (D) immune globulin (human). In cases of large fetal–maternal hemorrhages, a second quantitative test is recommended. This quantitation will guide the physician in the administration of additional amounts of Rh (D) immune globulin (human).
