A red blood cell antibody screen looks for antibodies in the liquid part of your blood that could react with red blood cells. It is used before blood transfusion and during pregnancy.

Yes. Antibody levels can fall until a later screen no longer detects them. Tell the care team about previous antibodies or show any antibody record you have. Earlier findings can still affect the choice of donor blood.
No. The antibody screen is an indirect test that looks for antibodies in the blood's liquid part. A direct Coombs test checks for antibodies already attached to red blood cells. The tests answer different questions.
