What it is

This test finds your ABO blood group: A, B, AB or O. It is done before transfusions or surgery, during pregnancy, and sometimes just so a person knows their blood type.

What the price covers

The price usually covers the ABO grouping only. The blood draw is often billed separately, and the Rh factor (86901) and antibody screen (86850) are separate codes.
