ABID2 - Specimen: Antibody Identification, Erythrocytes

Test Catalog

Test Name

Test ID: ABID2    
Antibody Identification, Erythrocytes

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

The following tests may also be ordered and performed as part of antibody identification: special red cell antigen typing, antibody elution, antibody absorption, direct Coombs, and monospecific direct Coombs. These additional tests will determine or confirm antibody specificity and allo- vs. autoantibody.

Specimen Type Describes the specimen type needed for testing


Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Include report of diagnosis and history of transfusions and pregnancy. If some antibody panel work has been done, include copies of the work.


Specimen must arrive within 72 hours of draw.


Blood and serum are required.


Specimen Type: Whole blood

Container/Tube: Lavender top (EDTA)

Specimen Volume: 18 mL

Specimen Minimum Volume: 6 mL

Collection Instructions: Send specimen in original tube.


Specimen Type: Serum

Container/Tube: Red top

Specimen Volume: 10 mL

Collection Instructions: Spin down and separate serum from clot.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

Blood: 6 mL

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected








Serum gel tube


Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
