Clinical Utilities
Used to determine the volume of fetal-to-maternal hemorrhage, for purposes of recommending an increased dose of RhIG.
Recommended standard of practice is to administer RhIG within 72 hours of the fetomaternal bleed for optimal protective effects. The effectiveness of RhIG decreases after 72 hours post exposure but may still be clinically warranted.
This assay has been validated up to 4 days post collection.
Rh Immune globulin (RhIG, anti-D antibody) binds to fetal D-positive red blood cells, preventing development of the maternal immune response. RhIG can be given after delivery. The volume of FMH determines the dose of RhIG to be administered.
