Rh Status and Antibody Screen
What Is Rh Factor???
How does a person get it ??
If you're Rh-negative and you've been pregnant before but didn't get this shot, another routine prenatal blood test will tell you whether you already have the antibodies that attack Rh-positive blood. (You could have them even if you miscarried the baby, or had an abortion)
Antibody Screen Test???
Antibody screening test, as part of pretransfusion compatibility testing (see Miscellaneous), along with the type and crossmatch, prevents transfusion reactions such as hemolysis from occurring.
