Test ID: ABTIH    
Antibody Titer, Erythrocytes

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: 7 mL

Collection Instructions: Spin down and separate plasma from cells. Send both tubes.


Specimen Type: Serum

Container/Tube: Red top

Specimen Volume: 10 mL

Collection Instructions: Spin down and separate serum from clot. Send both tubes.

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.
