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.

Container/Tube:

Preferred: Lavender top (EDTA)

Acceptable: ACD, heparin

Specimen Volume: 3 mL

Collection Instructions: 

1. Submit fresh specimen.

2. Do not transfer blood to other containers.

Additional Information: Patient's age is required.

Forms:

1. Thalassemia/Hemoglobinopathy Patient Information Sheet (Supply T358) in Special Instructions

2. If not ordering electronically, please submit a Hematopathology/Molecular Oncology Request Form (Supply T241) 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.
