By highlighting the presence of fetal red cells in the maternal blood and quantifying their proportion, the Kleihauer test makes it possible to adapt the quantity of anti-D immunoglobulin to be injected to the future mother in the context of the prevention of RhD fetomaternal alloimmunization in RhD negative women.
By partially or fully standardizing the Kleihauer test, the range dedicated to feto-maternal quantification allows laboratories to secure the achievement of staining.
