HbF Quantification by Flow Cytometry

Test Description

Quantifying fetal red blood cells in Rh-negative mothers plays a crucial role in assessing the risk of hemolytic disease of the fetus and newborn (HDFN), most often caused by Rh incompatibility. The utility of this test is to determine the dosing for Rh immunoglobulin (RhIg) administration to prevent sensitization and protect future pregnancies. Additionally, this test can quantify fetomaternal hemorrhage in obstetric trauma.
