Thalassemia and Hemoglobinopathy Evaluation
Specimen Type 
Describes the specimen type needed for testing
Whole blood
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.
Forms:
1. Thalassemia/Hemoglobinopathy Information Sheet (Supply T358) in Special Instructions
2. New York Clients-Informed consent is required. Please document on the request form or electronic order that a copy is on file. An Informed Consent for Genetic Testing (Supply T576) is available in Special Instructions.
3. If not ordering electronically, please submit a Hematopathology/Molecular Oncology Request Form (Supply T241) with the specimen.
Patient's age and sex are required. Include recent transfusion information.
Blood and serum are required.
Specimen Type: Whole blood
Container/Tube: Lavender top (EDTA)
Specimen Volume: 15 mL
Collection Instructions: Label specimen as whole blood.
Specimen Type: Serum
Container/Tube: Red top or serum gel
Specimen Volume: 0.6 mL

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.
