Methodology
Profile Information: | |
Type and Rh | Antibody Screen |
Method Name:
Tube Testing and Gel System
This test is performed to determine the patient’s blood group (ABO) and Rh type, as well as to detect the presence of irregular antibodies in the patient’s plasma or serum. If the antibody screen is positive, ABID “Antibody Identification", is performed (at an additional charge).
Note:
- If antibody screen is positive and specimen is intended for possible transfusion, 2 compatible packed red blood cells will be crossmatched (and charged).
- If crossmatched red blood cells are required, order RCLR, “Red Blood Cell Components.”
- See “Blood Banking (Transfusion Medicine)—Blood Transfusion Policies and Standard Practices” in Special Instructions for additional information.
