Test ID: CAGG    
Cold Agglutinin Titer, Serum

Specimen Type Describes the specimen type needed for testing

Serum Red

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.

Container/Tube: Red top

Specimen Volume: 4 mL

Collection Instructions:

1. Use a warm pack to keep specimen at 37 degrees C prior to and after collecting.

2. Allow specimen to clot at 37 degrees C.

3. Centrifuge at 37 degrees C and separate serum from red cells immediately after blood clots.

4. Do not refrigerate prior to separation of serum from red cells.

Forms: If not ordering electronically, complete, print, and send a Benign Hematology Test Request Form (T755) with the specimen (

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.
