Obstetric Panel. An obstetric panel is a group of blood tests done to check the health of a woman before and during early pregnancy. The results of these tests can help find certain problems during the pregnancy. They can also help guide any treatment needed for a woman during pregnancy or for a baby immediately after birth. Blood type, antibody screening, and a complete blood count (CBC) are all part of an obstetric panel.
The ABO Blood Group System. There are four major blood groups determined by the presence or absence of two antigens â A and B â on the surface of red blood cells: 1  Group A â has only the A antigen on red cells (and B antibody in the plasma).2  Group B â has only the B antigen on red cells (and A antibody in the plasma).n addition to the A and B antigens, there is a third antigen called the Rh factor, which can be either present (+) or absent (â). In general, Rh negative blood is given to Rh-negative patients, and Rh positive blood or Rh negative blood may be given to Rh positive patients.
