Useful For/Utility
Pretransfusion compatibility testing begins with the type and screen procedure. The recipient’s ABO group and Rh type are determined first; then a screening procedure is used to detect any unexpected non-ABO blood group antibodies that may be present.
If the screening test reveals the presence of an antibody, the specificity of that antibody is determined by an antibody identification panel. Once the specificity of the antibody has been identified, donor units of the appropriate ABO group and Rh type are screened for the corresponding antigen. Units that are negative for that antigen are crossmatched with the recipient to ensure compatibility.
Methodology
Tube Testing/Gel Card Testing
Includes #LAB8004 ABO/Rh for Non-Obstetrics and #8009 Antibody Screen.
Test Algorithm
If two blood types have not been previously performed at Essentia Health, a second ABO/Rh will be reflexed. This is only done once and is at no charge to the patient. Antibody Identification will be reflexed for positive antibody screen testing.
Two red cell components may be cross matched for inpatients type and screen who have a positive antibody screen and subsequent antibody.
Antibody titer will be completed for appropriate prenatal patients
Clinical Information
The ABO system is regarded as the most important blood-group system in transfusion medicine because of severe hemolytic transfusion reactions and, to a lesser degree, hemolytic disease of the newborn.
The Rh blood group system is the secondmost important blood group system, after the ABO blood group system.
An indirect antiglobulin test (IAT) demonstrates in-vitro reactions between red cells and antibodies, and is used in antibody detection, antibody identification. Because of the dire clinical consequences associated with ABO incompatibilities, ABO typing and ABO compatibility testing remain the foundation of pretransfusion testing and an important component of typing before transfusion/transplantation.
Specimen Requirements
Specimen must arrive within 3 days of draw.
Specimen Type: EDTA whole blood
Container/Tube: Pink top (K2EDTA)
Specimen Volume: 6 mL
Collection Instructions: Send specimen in original tube.
Additional Information:
1. Lavender-top (EDTA) tube is acceptable.
2. Instruct patient not to remove Blood Bank armband.
3. Label specimen for Blood Bank, see Transfusion Services in Special Instructions for labeling instructions.
Minimum Volume: Varies with patient condition. 1) For routine non-antibody patients, 2 mL of K2 EDTA whole blood. 2) In certain circumstances, additional blood may be requested to complete testing. If the patient has a known antibody, 2-3 6mL K2 EDTA whole blood tubes required.
