Laboratory studies may include the following:

  • Qualitative urine pregnancy test, to confirm pregnancy

  • Complete blood count with differential

  • Blood type and Rh factor: Blood type must be documented for every pregnant patient with vaginal bleeding. If Rh-negative, administer RhoGAM to prevent hemolytic disease of the newborn in this pregnancy and subsequent pregnancies.

  • Hemoglobin and hematocrit: These studies establish baseline and detect hemorrhagic anemia.

  • Factor XIII and fibrinogen, if indicated per history
