Test Code LAB8009 Antibody Screen

Additional Codes

Test Name in Epic EPIC Test Code Mnemonic
Antibody Screen LAB8009 ABSC

 

Test Alias

ABSC, antibody, screen, Type and Screen, type and screen

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.

Methodology

Gel Card Testing

Test Algorithm

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.                                                                             

Two red cell components may be cross matched for inpatient type and screens who have a positive antibody screen and subsequent antibody.

Clinical Information

An indirect antiglobulin test (IAT) demonstrates in-vitro reactions between red cells and antibodies, and is used in antibody detection, antibody identification.

Specimen Requirements

Specimen must arrive within 3 days of draw.

 

EDTA whole blood are required.

 

Specimen Type: Whole blood

Container/Tube: Pink top (K2EDTA)-Lavender top (EDTA) is also acceptable.

Specimen Volume: 6 mL of K2EDTA whole blood

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.

Collection Instructions: Send specimen in original tube.

Additional Information: Label specimen appropriately (K2EDTA) and for Blood Bank (see Transfusion Services in Special Instructions).
