Test ID: ABSCM    
Antibody Screen, Erythrocytes

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

If the antibody screen is positive, then antibody identification will be performed.

The following tests may also be ordered and performed as part of antibody identification: monospecific direct Coombs, special red cell antigen typing, antibody elution, and antibody absorption.

Specimen Type Describes the specimen type needed for testing

Whole Blood EDTA

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.

Specimen must arrive within 72 hours of draw.

 

Container/Tube: Lavender top (EDTA)

Specimen Volume: Entire specimen

Collection Instructions: Send specimen in original tube.

Forms: If not ordering electronically, complete, print, and send a Benign Hematology Test Request Form (T755) with the specimen (http://www.mayomedicallaboratories.com/it-mmfiles/benign-hematology-test-request-form.pdf)

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.
