then she receives RhoGAM if she has an Rh positive fetus,
but she does not receive it if the infant is negative.
She might have received antibodies as a fetus from her own mother if her mother was Rh positive, so she might already be sensitized before becoming pregnant herself.
Her Rh status must be tested first using indirect Coombs' test.
If she has a miscarriage, elective abortion, ectopic pregnancy or molar pregnancy, then a microdose of immune globulin is used within the first 12 weeks' gestation. So, is she routinely given the RhoGAM after these events, if she is tested and found unsensitized (after first being tested to determine if she is already sensitized)?
